To carry out a holistic economic appraisal of an integrated transport system it is necessary to take into account not only private and public transport users, but also individual pedestrians.Integrated transport systems make the objectives of traffic signal control more complicated. There are trade offs involved between pedestrian safety, bus and light rail priority. They include conflicting aims to reduce delays to pedestrian and to other road traffic. Over the last decade there has been an increase in interest in traffic microsimulation models.However, the key focus of these models has been the vehicular traffic and most often the mathematical simulation of pedestrian traffic has been ignored. This paper presents and audit of current pedestrian simulators and compares the theory and methodology used in their development. It presents and insight into nine different simulation programs which include PEDROUTE, PAXPORT, LEGION, SPACE SYNTAX suite, EXODUS, STEPS, PEDGO, SYMULEX and VISSIM.The study proposes a benchmarking mechanism to evaluate fitness of pedestrian simulators for applications in a transport context. The paper compares the results of applying the simulators (apart from LEGION) to a test site, highlighting the strengths and weaknesses of each of the simuylators. The paper also reviews past research into simulation of pedestrian movements and simulation of pedestrian paths.a simple pedestrian simulator has been developed for an application in VISSIM microsimulation package. A methodology has been developed to include pedestrian movements into the appraisal of integrated transport schemes which includes modelling the interaction of pedestrians with traffic signals, public transport systems and traffic. It comprises modelling of pedestrians on both a macroscopic and microscopic scale, together with all other traffic It includes dynamic assignment of pedestrian origin destination movements to replicate their route choices. Finally,an economic appraisal of the integrated transport scheme is carried out using Transport User Benefit Analysis software which takes into account vehicular time savings and pedestrian time savings. The study identifies areas of further research to make pedestrian simulation models more flexible by taking pedestrian route choice into account, to create a valuable policy analysis tool for the urban built environment.
