Determinants of following Headway in Congested Traffic
This paper reports on results of a study undertaken in the U.K. aimed at investigating factors affecting the car following process. An understanding of the factors affecting this complex decision making process is essential to a wide range of theoretical issues including driver workload, capacity and the modeling of freeway flow, as well as practical applications such as the design of in-vehicl...
متن کاملEvaluating the Time Headway Distributions in Congested Highways
Time headway is a significant traffic flow parameter that affects the capacity and safety of highways and freeways. Time headways are broadly used in different areas of traffic and transport engineering such as capacity analysis, safety studies, car following and lane changing behavior modeling, and level of service evaluation. In this paper, the time headway distribution is investigated for an...
متن کاملTraffic peak spreading in congested urban environments Traffic peak spreading in congested urban environments
The paper will describe the results of research recently completed, funded by Transfund New Zealand, into the phenomenon of traffic peak spreading in congested urban environments. The work looked specifically at two facets: 4 the extent to which traffic peak spreading has been observed and the underlying behavioural aspects 4 how (if) traffic peak spreading is modeled in different countries and...
متن کاملReproducible Features of Congested Highway Traffic
Observation of a 4-mile long, inhomogeneous, congested traffic stream revealed that vehicle accumulations between detectors vary with flow in a predictable way, and that a macroscopic kinematic wave with a reproducible speed exists in queues despite unusual traffic behavior. As a result, time-dependent vehicle trip times and accumulations inside long queues (and the queue length itself) can be ...
متن کاملAnalysis of Headway of Heterogeneous Traffic on Indian Urban Roads
Headway or inter-arrival time of vehicles is an important parameter in traffic flow, especially in urban roads, since this is one of the main parameters to determine the minimum (safe) gap between vehicles and the capacity. The studies done on headway analysis have mostly concentrated on homogeneous traffic where the flow follows lane discipline. This ideal situation does not exist on Indian ur...
