Capacity constrained stochastic static traffic assignment with residual point queues incorporating a proper node model
Bliemer, Michiel C.J.; Raadsen, Mark P.H.; Smits, Erik‐Sander; Zhou, Bojian; Bell, Michael G.H.Published 2014-03-01Static traffic assignment models are still widely applied for strategic transport planning purposes in spite of the fact that such models produce implausible traffic flows that exceed link capacities and predict incorrect ...Open AccessWorking Paper -
Continuous-time general link transmission model with simplified fanning, Part I: Theory and link model formulation
Bliemer, Michiel C .J.; Raadsen, Mark P.H.Published 2017-03-01The kinematic wave theory is widely used to simulate traffic flows on road segments. Link transmission models are methods to find a solution to the kinematic wave model, however, their computational efficiency heavily ...Open AccessWorking Paper -
Continuous-time general link transmission model with simplified fanning, Part II: Event-based algorithm for networks
Raadsen, Mark P.H.; Bliemer, Michiel C.J.Published 2017-03-01In this paper a novel solution algorithm is proposed for solving general first order dynamic network loading (DNL) problems in general transport networks. This solution algorithm supports any smooth non-linear two regime ...Open AccessWorking Paper -
An efficient event‐based algorithm for solving first order dynamic network loading problems
Raadsen, Mark P.H.; Bliemer, Michiel C.J.; Bell, Michael G.H.Published 2014-05-01In this paper we will present a novel solution algorithm for the Generalised Link Transmission Model (G-LTM). It will utilise a truly event based approach supporting the generation of exact results, unlike its time discretised ...Open AccessWorking Paper -
Extended Macroscopic Node Model for Multilane Traffic
Gong, Xiaolin; Bliemer, Michiel C.J.; Raadsen, Mark P.H.Published 2024-02-05In a macroscopic assignment model, traffic flows are distributed onto the network by means of a network loading model. The network loading propagates flows along links via a link model and through junctions or intersections ...Open AccessWorking Paper -
General solution scheme for the Static Link Transmission Model
Raadsen, Mark P.H.; Bliemer, Michiel C.J.Published 2018-11-01Until the present day most static traffic assignment models are neither capacity constrained nor storage constrained. Recent studies have resulted in novel approaches that consider capacity constraints and sometimes storage ...Open AccessWorking Paper -
Incorporation of Endogenous Exit Capacities in Node Models with Various Movement Exit Speeds
Gong, Xiaolin; Raadsen, Mark P.H.; Bliemer, Michiel C.J.Published 2024-07-18In macroscopic traffic assignment, the node model is fundamental for accurately capturing traffic dynamics at junctions and intersections, which are often the primary sources of travel delays in urban networks. The ...Open AccessWorking Paper -
Incorporation of non-persistent delays at signalised intersections in the link transmission model
Bliemer, Michiel C.J.; Gong, Xiaolin; Raadsen, Mark P.H.Published 2024-07-17In macroscopic dynamic traffic assignment, traffic flows are allocated to a transport network by means of a dynamic network loading model, with travel time being a primary output. Dynamic network loading not only determines ...Open AccessWorking Paper -
Introducing pattern graph rewriting in novel spatial aggregation procedures for a class of traffic assignment models
Raadsen, Mark P.H.; Bliemer, Michiel C.J.; Bell, Michael G.H.Published 2016-12-01In this study two novel spatial aggregation methods are presented compatible with a class of traffic assignment models. Both methods are formalized using a category theoretical approach. While this type of formalization ...Open AccessWorking Paper -
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.Published 2015-11-01In 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. ...Open AccessWorking Paper -
A review of (dis)aggregation and decomposition methods in traffic assignment
Raadsen, Mark P.H.; Bliemer, Michiel C.J.; Bell, Michael G.H.Published 2019-04-01In this study we provide a comprehensive review of the existing literature on (dis)aggregation and decomposition methods in traffic assignment. The study takes on two different perspectives. First, we explore existing ...Open AccessWorking Paper -
Steady-state link travel time methods: formulation, derivation, and classification
Raadsen, Mark P.H.; Bliemer, Michiel C. J.Published 2018-08-01Travel times are one of the most important outputs of transport planning models and this is unlikely to change in the future. It is therefore paramount that the methods that underpin the construction of travel times are ...Open AccessWorking Paper -
A Systematic Review of Node Models for Macroscopic Network Loading of Traffic Flows
Gong, Xiaolin; Raadsen, Mark P.H.; Bliemer, Michiel C.J.Published 2024-07-17Node models in macroscopic network loading procedures are used to distribute competing flows arising at motorway ramps, junctions, and intersections, influencing congestion and queuing delays. Despite decades of research ...Open AccessWorking Paper -
A unified framework for traffic assignment: deriving static and quasi‐dynamic models consistent with general first order dynamic traffic assignment models
Bliemer, Michiel C.J.; Raadsen, Mark P.H.; Brederode, Luuk; Bell, Michael G.H.; Wismans, Luc J.J.Published 2014-04-01This paper presents a theoretical framework to derive static, quasi-dynamic, and semi-dynamic traffic assignment models from a general first order dynamic traffic assignment model. By explicit derivation from a dynamic ...Open AccessWorking Paper
