Identifying crash propensity using specific traffic speed conditions.
INTRODUCTION In spite of recent advances in traffic surveillance technology and ever-growing concern over traffic safety, there have been very few research efforts establishing links between real-time traffic flow parameters and crash occurrence. This study aims at identifying patterns in the freeway loop detector data that potentially precede traffic crashes. METHOD The proposed solution ess...
متن کاملModelling crash propensity of carshare members.
Carshare systems are considered a promising solution for sustainable development of cities. To promote carsharing it is imperative to make them cost effective, which includes reduction in costs associated to crashes and insurance. To achieve this goal, it is important to characterize carshare users involved in crashes and understand factors that can explain at-fault and not-at fault drivers. Th...
متن کاملDetermining Parameter Limits in Traffic Crash Reconstruction Using Limited Data
Quantities used in crash reconstruction often have inherent variation and a single value is not appropriate. A common way to overcome this deficiency is to use a range. This paper will present a technique, based on sampling statistics, to determine a range in a logical and mathematically consistent fashion. If the parameter in question is normally distributed, then the Student-t and χ2 (chi-squ...
متن کاملProactive Freeway Crash Prevention Using Real-Time Traffic Control
This paper makes use of a probabilistic model, that predicts the likelihood of crashes (crash potential) on freeways on the basis of traffic flow conditions, in real-time crash prevention. The model was developed using incident logs and loop detector data collected over a 13-month period on the Gardiner Expressway in Toronto. The previous work suggested that an increase in levels of traffic tur...
