|Abstract:||The taxi, as a supplier of urban passenger transport, is often sidelined in travel demand studies, yet its role in the overall transport task is far from marginal. Taxis are the most intensively used automobile transportation and consequently have a very high exposure rate in respect of potential accident. Very little empirical research has been undertaken into the risks associated with using a taxi. Drivers of taxis are usually assumed to be experienced drivers with a safety history appropriate for the responsibility of transporting the public. Yet this is not always the case. To provide some understanding of the exposure to risk which passengers place themselves in when hiring a taxi, we explore the safety record of drivers over time. Of particular interest is the frequency of accidents over a given time period, and in particular the elapsed time between a taxi drivers initial accident and subsequent accidents. To what extent is the duration between accidents a positive or negative function of experience, personal attributes, temporary impairment, fatigue etc? A set of proportional hazards models are developed to explain the time interval (duration) between traffic accidents of taxi drivers in Amman, Jordan. Three econometric models are developed to predict the duration between the date when a taxi driver begins to drive and the date when the first, second, and third accidents occur respectively. Estimation results show that driving-related capabilities, socioeconomic characteristics, and temporary impairments significantly influence the duration between traffic accidents. The duration to the first traffic accident is lower than the duration between the first|
