MOTORWAY SPEED CONTROL STRATEGIES USING SISTM

SISTM (Simulation of Strategies for Traffic on Motorways) is a microscopic motorway simulation programme for investigating alternative traffic management measures. It has been enhanced to model variable speed limit systems such as the system currently in operation on part of the M25. Version 4.1 of the software can model different parmeter values for the flow thresholds, the flow measurement periods and smoothing factors. Traffic data from this section has been used to predict the effect of 50 and 60mph speed limits on the target speed of drivers in SISTM. This paper describes SISTM's speed control modelling and how it is calibrated for speed control operations. For the covering abstract see IRRD 880251.
