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...

There is a potential tension between the theoretical desirability of highly differentiated tariff structures and the ability of consumers to respond effectively to them. Evidence from studies of road pricing schemes and tolls, from other transport modes, and from other industries (notably...

Information about travel demand, traveller behaviour and transport systems performance is an essential input to decision making on transport policy, planning and design issues. However, this information is difficult and expensive to collect and establish, so that its collection has been...
