The pedestrian behaviour model allows you to predict the number of pedestrians that will cross during the red man as well as during the green man, i.e. the level of non-compliance is predicted. Given the high proportion of pedestrians that do no comply, the new model allows far more accurate calculations of pedestrian delay than would have been possible previously, when TRANSYT would have simply assumed pedestrian would only cross during the green man.
The model has been derived from research based on the extensive analysis of pedestrian behaviour in London. A mechanism has also been added to allow some calibration to the model – this allows some site-specific differences to be accounted for and also offers a mechanism to adjust the model for use outside of London where pedestrian behaviour may well be different.
