This paper discusses issues that are encountered in the modelling of the operational behaviour of pedestrians such as the representation of pedestrian street crossing movements and speed choice at a micro-scale. A comprehensive literature review is undertaken for various parameters of pedestrian movement that are of fundamental importance in any pedestrian modelling approach. These parameters are pedestrian speeds, pedestrian speed-flow-density relationships, pedestrian compliance to traffic signals, and pedestrian gap acceptance while crossing the road. Based on the research evidence from the literature, a modelling framework for examining pedestrian speed choice is presented that postulates that pedestrian speed is a function of a pedestrian's value of time, risk and capabilities.
