Junction user equality and evaluation

Government policy encourages UK local authorities to make walking more attractive. The retiming of traffic signals could reduce pedestrian delays, but may have a significant effect on other road traffic. The Walking Plan for London and the Traffic Management Act (TMA) require that pedestrians are treated equitably. Transport for London (TfL) commissioned Jacobs Babtie to assess how pedestrian behaviour could be modelled and assessed with microsimulation computer software packages. A TfL VISSIM model of the Shoreditch area was selected for analysis. A number of policy options were tested e.g. changes in signal timing, coordination of pedestrian green cycles between intersections and the removal of staggers at pedestrian crossings. A Multi-Criteria Evaluation Framework was developed to assess the impact of the different options on pedestrians and other road users. Parameters and values extracted from the microsimulation models were travel time, density, number of stops, queue time, distance travelled, speed and delay. The multi criteria and ranking system was used to collate the positive and negative impacts for all road users. Removal of crossing stagger was ranked first, with additional pedestrian crossings second and changing signal timings third.
