Using contracted assets to undertake non‐contracted services as a way to improve cost efficiency under negotiated or tendered bus contracts Hensher, David A. Public transit (bus) operators in many jurisdictions throughout the world currently deliver regular public transport (RPT) services under a negotiated contract, typically between five and 10 years, with re-negotiation commonly assumed. In the last 20 years, however there has been a move to competitively tendered service supply or a dialogue as a pre-phase to considering competitive tendering (CT). Despite the growing interest in CT in the belief (almost ideological in many situations) that CT will deliver value for taxpayers money in contrast to negotiated contracts, accumulating evidence suggests that negotiated performance-based contracts associated with a well designed and effective actionable benchmarking program with high quality incumbent service providers, can provide as good if not better value for money to government and society. Much of the evidence is now well documented in the literature; however there is one feature of the contracting environment that has not been given sufficient consideration, namely the complementary role that non-contracted services such as charter activity can play in improving the cost efficiency of contracted services. This paper investigates this phenomenon in the context of Sydney (Australia) bus service provision, aligned to the literature on output-based incentives, and shows that operators who participate in greater non-contracted services, while also delivering contracted services, have higher cost efficiency (in terms of cost per contracted in-service kilometres). While this can be explained in part by the quality of such operators, who are often more entrepreneurial and better managers, the evidence suggests that if operators can be encouraged (or allowed) to use contract assets to gain supplementary revenue (without incurring the same unit rate of costs per kilometre), then the negotiated (or tendered) prices are likely to be lower than they would otherwise be. Making this opportunity explicit is equivalent to adding an element of increased incentive compatibility.

Speeding in urban environments: Are the time savings worth the risk? Ellison, Adrian B.; Greaves, Stephen Perceived time savings by travelling faster is often cited as a motivation for drivers’ speeding behaviour. These time savings, however, come at a cost of significant road injuries and fatalities. While it is known that drivers tend to overestimate the time savings attributable to speeding there is little empirical evidence on how much time drivers genuinely save during day-to-day urban driving and how this relates to speeding-related crashes. The current paper reports on a study to address the lack of empirical evidence on this issue using naturalistic driving data collected from 106 drivers over a period of five weeks. The results show that the average driver saves 26 seconds per day or two minutes per week by speeding. More importantly, the cost of these time savings is one fatality for every 18,947 hours saved by the population on 100 km/h roads and one injury for every 1,407 hours saved on the same roads. Full speed compliance – and consequently a dramatic reduction in the road toll – could be achieved through almost imperceptible increases in travel time by each driver.

Travel behaviour in the context of parcel pickups Collins, Andrew The last decade has seen a rapid growth in business to consumer parcel deliveries, driven to a large extent by a corresponding growth in online shopping. However, the ‘last mile’ of parcel distribution, which involves the final physical transfer of goods to the customer, is particularly problematic for many customers. Failed deliveries are common, notwithstanding some market moves to extend delivery hours and narrow delivery windows. An alternative that has become increasingly prevalent is the collection/delivery point (CDP). Parcels are delivered to a CDP of the customers’ choosing, and then picked up at the customers’ convenience. This study investigates travel behaviour in the context of choice between conventional delivery and CDPs. A stated choice survey is employed to test the impact of alternative delivery and CDP offerings. An error components logit model is estimated which handles the joint choice of delivery verses pickup, and pickup location, travel mode, trip chaining, and trip scheduling. The results reveal complex interactions between the various choices, with key differences across the choices in the influence of the attributes of the choice alternatives, the characteristics of the households that constitute the decision makers, and the nature of the parcel being delivered. This study shows that as last mile delivery and pickup services evolve, the changing quality of these services will have an impact on shopping travel behaviour.

A resilient and sustainable supply chain: Is it affordable? Fahimnia, Behnam; Jabbarzadeh, Armin Developing environmentally and socially sustainable supply chains has become an integral part of corporate strategy for virtually every industry. However, little is understood about the broader impacts of sustainability practices on the capacity of the supply chain to tolerate disruptions. This article aims to investigate the sustainability-resilience relationship at the strategic supply chain design level using a multi-objective optimization model and an empirical case study. The proposed model utilizes a sustainability performance scoring method and a novel programming approach to perform a dynamic sustainability tradeoff analysis and design a “resiliently green” supply chain.

Power and the illusion of control: Do individual’s correctly anticipate how much influence they have within a household choice? Beck, Matthew J.; Rose, John M. Choices of groups remain one of the lesser studied behaviours in the choice literature. This continues to be an oversight as many choices are made at a household or even social level. In particular, studies that seek to further our understanding of the role of individual influence in group choices remain uncommon. This paper presents the first steps of research into an even less researched area of group choice; the level of influence that individuals think they have over a group choice. In the context of motor vehicle choice among household dyads, we find that individuals mostly perceive influence to be equally shared across vehicle attributes, with the primary user of the motor vehicle, on average, perceiving themselves to be more influential than their partner. While the primary user may perceive them self to be more influential this is mismatched with what is uncovered by modelling group powers. Influence of the primary agent is limited to the type of fuel the vehicle uses. We find that perceptions of influence are predominantly a function of attitudes about vehicle emissions and the age of the individual. Overall we provide new evidence into the ability of people to assess their own influence in a negotiation process, the influence of another and the sources of discrepancy that may exist, thus adding richer insights to the contextual understanding of group decisions.

Random regret minimisation and random utility maximisation in the presence of preference heterogeneity: An empirical contrast Hensher, David A.; Greene, William H.; Ho, Chinh Random regret minimisation (RRM) interpretations of discrete choices are growing in popularity as a complementary modelling paradigm to random utility maximisation (RUM). While behaviourally very appealing in the sense of accommodating the regret of not choosing the ‘best’ alternative, studies to date suggest that the differences in willingness to pay estimates, choice elasticities and choice probabilities compared to RUM are small. However, the evidence is largely based on a simple multinomial logit form of the RRM model. In this paper we revisit this behavioural contrast and move beyond the multinomial logit model to incorporate random parameters, revealing the presence of preference heterogeneity. The important contribution of this paper is to see if the extension of RRM-MNL to RRM-mixed logit in passenger mode choice widens the behavioural differences between RUM and RRM. The current paper has identified a statistically richer improvement in fit of mixed logit compared to multinomial logit under RRM (and RUM) but found small differences overall between the empirical outputs of RUM and RRM, with no basis of an improved model fit between these two non-nested model forms. The inclusion of both model forms should continue to inform the likely range of behavioural outputs as we investigate a broader range of process heuristics designed to capture real world behavioural response.

A lossless spatial aggregation procedure for a class of capacity constrained traffic assignment models incorporating point queues Raadsen, Mark P.H.; Bliemer, Michiel C.J.; Bell, Michael G.H. In this paper two novel spatial aggregation procedures are proposed. A network aggregation procedure based on a travel time delay decomposition method and a zonal aggregation procedure based on a path redistribution scheme. The effectiveness of these procedures lies in the fact that they, unlike existing aggregation methods, exploit available information regarding the application context and the characteristics of the adopted traffic assignment procedure. The context considered involves all applications that require path and inter-zonal travel times as output. A typical example of such applications are quick-scan methods, which have become increasing popular in recent years. The proposed procedures are compatible with a class of traffic assignment procedures incorporating (residual) point queues. Furthermore, one can choose to combine network aggregation with zonal aggregation to increase the effectiveness of the procedure. Results are demonstrated via theoretical examples as well as a large-scale case study. In the case study it is shown that network loading times can be reduced to as little as 4% of the original situation without suffering any information loss.

A simplified and practical alternative way to recognise the role of household characteristics in determining an individual’s preferences: the case of automobile choice Hensher, David A.; Ho, Chinh; Beck, Matthew J. It is common practice in choice modelling to include the socioeconomic characteristics of other members of a household in the utility expressions associated with the preferences of a particular individual. By including household descriptors, the analyst is assuming that other household members can influence the choices made by the household as if the preference weights (or marginal utilities) are reflective of equal influence of all members of a household. In reality it is likely that there is a power relationship that underlies the contribution of the individual whose preferences are being studied and the contribution of other household members, typically proxied by a number of socioeconomic descriptors. In this paper we condition the individual and the household explanatory variables on an additional parameter that represents the influence or power that each agent has in the revelation of the preferences of a sampled individual. Using a data set of the stated choice of automobile fuel type (petrol, diesel, hybrid), we estimate a nonlinear model to identify the strength of the power relationship, and find that the power contribution of the household members to the individuals choice vary across alternatives. The model with the power relationship is found to be a statistical improvement and delivers substantially different elasticities than the traditional model with household characteristics.

Detecting dominancy and accounting for scale differences when using stated choice data to estimate logit models Bliemer, Michiel C.J.; Rose, John M.; Chorus, Casper G. Stated choice surveys have been used for several decades to estimate preferences of agents using choice models, and are widely applied in the transportation domain. Typically orthogonal or efficient experimental designs underlie such surveys. These experimental designs may suffer from choice tasks containing a dominant alternative, which we show is problematic because it affects scale and therefore may bias parameter estimates. We propose a new measure based on minimum regret to calculate dominancy and automatically detect such choice tasks in an experimental design. This measure is then used to define a new experimental design type that ensures tradeoffs within the design. Finally, we propose a new regret-scaled multinomial logit model that takes the level of dominancy within a choice task into account. Results using simulated and empirical data show that the presence of dominant alternatives can bias model estimates, but that making scale a function of a smooth approximation of normalised minimum regret can properly account for scale differences without the need to remove choice tasks with dominant alternatives from the dataset.

Frequency‐based transit assignment revisited Bell, Michael G. H.; Bliemer, Michiel; Raadsen, Mark This working paper reformulates the Spiess and Florian frequency-based transit assignment method in matrix algebra revealing a new solution method. It is shown that the number of destination-specific passenger wait times at stops is equal to the number of flow conservation constraints (Proposition 1). The frequency-based transit assignment is found by matrix manipulation and when there are line capacity constraints the equilibrium effective frequencies are obtained iteratively. The existence of equilibrium effective frequencies is proven (Proposition 2). It is shown that a wider range of fare schemes, for example flat fares, can be modeled by the use of legs in the network representation. Numerical examples are presented and solved by R code.

Working while travelling: what are implications for the value of travel time savings in the economic appraisal of transport projects? Wang, Baojin; Hensher, David In the current practice of the economic appraisal of transport projects, the value of travel time savings (VTTS) for business trips is derived from the Cost Saving Approach (CSA) whereby travel time savings were valued at the Marginal Product of Labour (MPL), defined as the average wages plus on costs. This approach has been adopted nationally by Austroads and Transport for NSW, and internationally by UK and other European countries. It assumes that business travellers do not undertake any productive activities while travelling and that all travel time savings will be used for business and not leisure. Supported by portable computing devices, there is a view that an increasing proportion of business travellers and commuters work while travelling. On the other hand, a significant proportion of business travel time savings has been used for leisure instead of work. This paper uses the Hensher Equation developed in the 1970s to obtain an alternative valuation of contemporary business travel time savings by introducing two productivity foregone corrections for (1) the productive use of travel time, and (2) unproductive use of business travel time savings. The purpose of this paper is to translate recent research on the valuation of business travel time savings into practical tools for incorporation in economic appraisal methods.

Spatial variations of the effects of bus rapid transit on residential property values Mulley, Corinne; Ma, Liang; Clifton, Geoffrey; Yen, Barbara; Burke, Matthew Public transport investment is normally targeted at increasing accessibility which land rent theory identifies will increase land values. There is clear interest in how much land values increase to establish whether there is sufficient uplift to capture to help pay or contribute to investment plans. Identifying uplift for residential land has been well studied in the context of new light rail systems and bus rapid transit (BRT) systems in developing countries but there is little evidence for BRT in developed countries. This paper has two objectives. First, to examine long term impact of BRT in a developed world context in Brisbane, Australia as studies in Sydney, Australia, suggest little uplift in comparison to developing world contexts but this maybe from its isolated suburban location in contrast to the extended BRT network in Brisbane. Second, to consider the spatial distribution of uplift which is an essential pre-requisite to understanding the distributional impact if uplift is used to contribute to infrastructure provision. Spatial modelling is used to examine the accessibility impacts of the BRT and this is followed by Geographical Weighted Regression, used to examine the spatial distribution of accessibility. The results show there is greater uplift in Brisbane, as compared to Sydney, Australia which is likely due to the greater network coverage of BRT in Brisbane and a relative lack of rail based competition.

The challenge of obtaining ground truth for GPS processing Stopher, Peter; Shen, Li; Liu, Wen; Ahmed, Asif The increasing use of GPS as a substitute or complement to conventional travel surveys has brought with it an increasing need for a reliable source of ground truth, i.e., information on the actual travel in which each respondent engaged, including the mode and purpose of such travel. Over the past decade or so, the main source that has been used for providing ground truth is the prompted recall survey. As the survey task has become less of a challenge, it has become evident that the prompted recall survey is subject to many of the same shortcomings as most selfadministered surveys, with reporting error, misunderstanding of what constitutes a trip, etc. In this paper, we review some of the common problems encountered in prompted recall surveys, especially those undertaken at some period of time after the GPS survey was undertaken, and using self-report methods. Following this, the paper describes a recent experiment in using life-logging cameras to record a person’s travel, together with GPS, thereby providing a new source of ground truth data that is not subject to processing issues of the GPS data, nor to self-report or other issues with prompted recall data.

Using complex network theory to model supply chain network resilience: a review of current literature Perera, Supun; Bell, Michael G.H. Traditionally, supply networks are modelled as multi-agent systems, in order to represent explicit communications between various entities involved. However, due to the increasingly complex and interconnected nature of the global supply networks, a recent trend of research work has focussed on modelling supply networks as complex adaptive systems. This approach has enabled researchers to investigate various topological properties which give rise to resilience characteristics in a given supply network. This paper presents a critical review of the published research work on this field. Key insights provided by this paper include; (1) the importance of defining the concepts of ‘resilience’ and ‘disruptions’ as measurable variables; (2) the limitations of existing network models to realistically represent supply networks; (3) potential improvements to the currently used growth mechanisms, which rely on node ‘degree’ to derive attachment probability instead of the more realistic and relevant node ‘fitness’; (4) importance of incorporating operational aspects, such as flows, costs, and capacities of connections between the nodes as well as topological aspects; and (5) derivation of a new set of resilience metrics capturing operational as well as topological aspects. Finally, a conceptual approach incorporating the above improvements to the existing supply network modelling approach is presented.

The influence of key determinants on consumers’ choice in tourism destination Lok, Peter; Cheng, Vincent; Rhodes, Jo This study aims at developing a model that explains the effect of different stimuli types (ST) (i.e. online reviews and advertising) on a tourist’s intention to visit (ITV) a new destination. Two separate studies were conducted to establish and validate the model that consists of stimulus mediators (SM): destination trust (DT) and interest (DI). 113 surveys were obtained in study 1 which focused on the effect of the different stimuli types. Study 2 used the Elaboration Likelihood Model (ELM) to explore how advertising could persuade consumers to make purchasing decisions and how tourists could be persuaded to visit attraction sites. 146 surveys were obtained in study 2. Structured equation model (SEM) technique was adopted in the data analysis. The result of the first study showed that advertising has a stronger effect than positive online reviews. The second study showed that peripheral route of elaborate likelihood model has a stronger effect than central route in the context of tourism. That is, peripheral route that could generate a strong spontaneous impact by providing a vivid portrait of what a tourist would experience through an image cue.

Collecting longitudinal data from freight operators: survey design and implementation Ellison, Richard B.; Greaves, Stephen P.; Hensher, David A. Freight transport research has generally been limited by a lack of data of the breadth and quality available for passenger transport, particularly in terms of behavioural data. Although there are a number of reasons for this lack of data, the challenges of collecting freight data including the expense, participant burden and confidentiality issues are amongst the most significant. Although some improvements in technology and survey design have allowed for the collection of more behavioural freight data more improvements would be beneficial. This paper discusses the survey design and implementation of a survey intended to collect longitudinal behavioural data on the responses of freight transport firms to the introduction of environmental policies. The design of the survey is centred around a hypothetical scenario where respondents are asked how they would complete a given freight task within common constraints including time windows and delivery requirements. One of the key components of the survey design is a dynamic component that is intended to simulate the changing business environment to which firms are required to adapt. This paper also looks at the participant burden involved in completing the survey and compares how this differs depending on how respondents completed the survey.

Air safety & security: Traveller perceptions post the Malaysian Air disasters Beck, Matthew J.; Rose, John M.; Merkert, Rico Air transport is of substantial importance to economies, societies and freedom as it connects businesses and individuals with the world. However, two recent Malaysia Airlines incidents have resulted in even more security measures at airports and have anecdotally changed the security and safety perceptions of the traveling (or no longer traveling) public. Our study investigates for the first time attitudes towards air travel, safety and security and determines empirically if travellers are willing to experience even more invasive security measures in light of these tragedies. Our results suggest that there is a latent demand for air services despite the recent of the Malaysian Airline tragedies. Out of our proposed measures the presence of visible uniformed police creates the greatest feeling of security and it is seen as important to better communicate what security operations do and why it is effective in threat minimisation. We find willingness to pay for avoiding additional incidents both in terms of money and time but respondents are also willing to pay more to speed up the security process. Our results also suggest there is no desire to accept security processes that invade privacy considerably more what is currently practiced. We conclude that with respect to air travel the magnitude of trade-of between personal freedoms for improved security is limited. Travellers appear willing to accept risks, or perceive them as isolated and limited to airlines with inferior safety records and/or destinations with inferior security records.

Emission charge and liner shipping network configuration ‐ an economic investigation of the Asia‐Europe route Dai, Wayne Lei; Fu, Xiaowen; Yip, Tsz Leung; Hu, Hao; Wang, Kun This paper models shipping lines’ operational costs and CO2 emissions under alternative geographic network configurations when an emission charge is imposed on operations from Asia to Europe. Our modeling results suggest that shipping firms’ network configuration is influenced by emission charge, fuel price, port loading and unloading cost, and demand pattern of cargo transport across different markets. Total emission will be reduced by an EU emission charge scheme. However, if the charge is above a threshold, carriers will reconfigure shipping networks to minimize their costs including emission charge payments. This will offset part of the emission reduction achieved by the emission scheme. As a result, a higher charge does not always lead to a higher emission reduction. In addition, the performance of major ports along the Asia-Europe routes will be influenced in different ways, leading to conflicting views from regional governments. These findings reveal possible market distortions associated with regional emission systems, and highlight the complex effects of international environmental policies when market dynamics are considered.

Greening demand chains in urban passenger transport: Emissions saving from complex trip chains Ho, Chinh; Hensher, David A. It is well known that a significant amount to passenger trip activity involves multiple modes, destinations and trip purposes. For example, with multi-worker households, we observe a car commuter taking a child to a child care centre en route to work and also dropping their partner off at another location such as a railway station. This example is one of many trip chain configurations that represent the complexity of travel activity, and which have important implications on how we represent travel demand in transport planning models. What is not well understood is the impact that trip chaining has on greening the demand chain. We are unaware of any studies that have investigated the greening of passenger demand chains associated with the complexity of trip chains. This chapter uses the Sydney Household Travel Survey and an econometric model to identify the impact that the changing nature of trip chains has on CO2 emission. Results suggest that trip chains were stable in Sydney over a period of 15-year from 1997/87 to 2011/12. Emissions saving from chaining multiple activities into a single chain were found to vary between 5% to 19% depending on whether the mode of travel is car, bus, or train.

Logistics challenges for China: drivers of the logistics industry growth, and bottlenecks constraining development Hensher, David A.; Zhang, Zeyan; Rose, John M. In the last two decades, the Chinese economy has witnessed extraordinary growth. China is not only the world’s manufacturing centre and major market, but also an engine for the world’s economic growth. Within this context, China’s transport and logistics industry, as the lifeblood of its economic growth, is attracting increasing attention from industry practitioners and researchers. Given the importance of this sector, understanding industry developments and likely trends over the next few years is a valuable exercise, highlighting the key factors driving such growth, as well as the bottlenecks challenging the transport and logistics industry. This paper reviews the current status of the Chinese transport and logistics industry, analyses industry trends and potential factors driving the industry’s ongoing development including the challenges obstructing growth. China’s extraordinary economic growth, particularly the emerging e-commerce market in China, exposes a number of weaknesses that the Chinese logistics industry is currently not well prepared to adapt to.

Airport capacity choice under airport-airline vertical arrangements Xiao, Yibin; Fu, Xiaowen; Zhang, Anming This study investigates the effects of airport-airline vertical arrangements on airport capacity choices under demand uncertainty. A multi-stage game is analyzed, in which competing airlines contribute to capacity investments and at the same time share airport revenues. Our analytical results suggest that for a profit-maximizing airport, such a vertical arrangement leads to higher capacity although its profit may not be higher. For a welfare-maximizing airport, such an arrangement has no effect on capacity or welfare. Capital cost savings brought by airport-airline cooperation, if any, always leads to higher capacity, higher profit for a profit-maximizing airport, and higher welfare in the case of a welfare-maximizing airport. Numerical simulations reveal that win-win outcomes may be achieved for an airport and its airlines without government intervention.

The Impact of Bus Rapid Transit on Housing Price and Accessibility Changes in Sydney: a Repeat Sales Approach Mulley, Corinne; Tsai, Chi-Hong New public transport infrastructure is expected to improve the accessibility for local residents, and thus contribute to the land value uplift. The contribution that a bus rapid transit (BRT) system can make to land value uplift is less certain than for rail based systems with the literature mostly containing bus-based examples from developing countries with extensive BRT networks. This paper considers a BRT system named the “Liverpool-Parramatta Transitway” (LPT) was implemented in the South-West of Sydney in 2003 to improve public transport accessibility in the local area. A repeat sales model is constructed to investigate the impact of the LPT on residential housing prices and accessibility changes using repeat sales data from before and after the opening of the LPT. This identified little price difference between properties close to LPT stations and outside of the area that could be considered as affected by the LPT service coverage. This outcome is at variance with the theoretical underpinning of land value uplift and other empirical evidence relating to the LPT. Hedonic models using the same repeat sales data investigate the study area in more detail, stratifying the sample by housing type and by comparing separate before and after models. These research outcomes identify the extent to which the BRT system has an impact on local housing prices through accessibility improvements to the study area and provide a deeper understanding as to how the quantification of land value uplift from BRT represents one element of the wider economic benefits of a BRT system.

The challenges and opportunities of in-depth analysis of multi-day and multi-year data Moutou, Claudine; Longden, Thomas; Stopher, Peter; Liu, Wen The paper uses a unique multi-day multi-wave panel dataset of households and their travel to conduct new in-depth analysis on the influence of life change events and travel behaviour, specifically in relation to the travel time stability of individuals that participated in five or more waves. The popularity of mobile devices offer greater low-cost opportunities for collecting detailed travel data records may increase opportunities to analyse how life change events and travel behaviour. This paper discusses issues for designing pragmatic research designs that are robust to be expanded to become longitudinal, or combined with other datasets.
