Headway distributions in highway traffic flowse the inverse of the mean time headway is the rate of flow, headways have been described as the fundamental building blocks of traffic flow. When the traffic flow reaches its maximum value then the time headway reaches its minimum value.

Intersections with priority controlersection a vehicle transfers from the route on which it is travelling to another route, crossing any other traffic streams which flow between it and its destination. To perform this manoeuvre a vehicle may diverge from, merge with, or cross the paths of other vehicles.

The external cordon and screenline surveysThe object of the external cordon survey is to obtain information on the trips originating outside the external cordon having origins within the external cordon or passing through the survey area.

Trip distributionTrip distribution is another of the major aspects of the transportation simulation process and although generation, distribution and assignment are often discussed separately, it is important to realise that if human behaviour is to be effectively simulated then these three processes must be conceived as an interrelated whole.

The evaluation of transportation proposalsThe object of the simulation of the land-use/transportation process is to estimate the trips that will be attracted to a proposed future transportation system for a given pattern of land-use development. To compare effectively different transportation proposals it is imperative that each proposal should be evaluated.

Traffic speed distributions and estimationOne of the fundamental parameters for describing traffic flow is the speed, either of individual vehicles or of the traffic stream. It is of importance in work connected with the theory of traffic flow because of the fundamental connection between speed, flow and concentration when the movement of a traffic stream is being considered.
