The interaction between car parks and the transport system is a function of the traffic flows and the design of the interfaces (entrances and exists). Existing analytical models can only be used to estimate the delay at unsignalised car park entrances and exists under certain restricted and sometimes unrealistic conditions. This paper outlines a model (SCENE) which can be used to investigate car park intersection layouts. Three types of unsignalised car park entrances and exists are considered in SCENE. The first type contains only one lane for both exit and entry vehicles. The second allows vehicles to enter and exit in separate lanes, while the third has one entrance lane and two exit lanes for the left-turn and right-turn vehicles. SCENE has two forms of output: the first, a detail report, lists the arrival time, movement, head-of-queue arrival time, departure time, queue length experienced and head-of-queue delay as well as the total delay of every vehicle simulated after the warm-up period. The second, a summary report, contains the statistical measures for the queue length, head-of-queue delay and total delay of vehicles using each approach. The average head-of-queue delay and total delay of all vehicles are also calculated.
