Modelling of acceleration and deceleration distances and times associated with speed change cycles (stop-start and slow down-speed up manoeuvres) under normal driving conditions is essential for the analysis of operating cost, fuel consumption and pollutant emissions, as well as for determining geometric, stopped and queuing components of overall delay (Akcelik and Associates 2002). Similarly, modelling of acceleration and deceleration characteristics of individual vehicles is a key issue in relation to the accuracy of microsimulation models (Akçelik and Besley 2002).

A polynomial model of acceleration and deceleration profiles was derived for estimating instantaneous acceleration and deceleration rates, and the model was calibrated using extensive real-life driving data representing general driving conditions, ie involving a wide range of speeds change cycles on different road types (Akçelik and Biggs 1987 …
