This paper presents a numerical stability analysis of a multi-phase car-following model under mild to severe disturbances. The results show that local stability was always conformed. An asymptotically unstable region was found for traffic in congested states. One of the previously calibrated...

<title>A<sc>bstract</sc> </title> A wide range of public transport schemes have been proposed and put in practice to improve bus service reliability (including bus lanes, bus priority signals, passenger information systems, etc.). Central to the successful evaluation of such operational and management measures is to...

Traffic simulation models make assumptions about the safety-related behaviour of drivers. These assumptions may or may not replicate the real behaviour of those drivers who adopt seemingly unsafe behaviour, for example running red lights at signalised intersections or too closely following the...

Motorway merging has been regarded as a major source of conflicts and congestion, but has long been recognised as an area in which modelling has been relatively weak. The current traffic models represent the traffic operations at a merge are based on gap-acceptance approach, with the merging...

Macroscopic fundamental diagrams (MFD) of traffic for some networks have been shown to have similar shape to those for single links. They have erroneously been used to help estimate the level of travel in congested networks. We argue that supply curves, which track vehicles in their passage...

There has been rapid growth in interest in real-time transport strategies over the last decade, ranging from automated highway systems and responsive traffic signal control to incident management and driver information systems. The complexity of these strategies, in terms of the spatial and...

In this paper, a time-varying pricing model of a road bottleneck with elastic traffic demand is formulated using the optimal control theory. It is assumed that the optimal use of the bottleneck is achieved when social benefit over the whole time horizon of study is maximized. The necessary...
