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...

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...

Most previous theoretical arguments on congestion pricing are based on the fundamental economic principle of marginal-cost pricing, and are entirely concerned with abstract travel demand-supply models. There exists in the literature considerable confusion on analysis of congestion which needs to...

Previous analysis of bottleneck congestion and departure time choice have focused on the trade-off between queuing delay cost and early/late arrival penalty for a given work start schedule. The actual scheduling of travel and work activities may well depend on some other important factors, such...

High-occupancy-vehicle (HOV) lanes and toll differentiation have been used as efficient measures to address growing traffic congestion problems by providing priority treatment for buses and carpools. This paper deals with carpooling behavior and optimal congestion pricing in a multilane highway...
