NETSIM is a powerful microscopic simulation model and has been applied to numerous traffic studies. However, it appears that there are few attempts to use it to study bus operations. One of the possible reasons may be the difficulty in modeling some of the unique characteristics in bus operations. A similar challenge was faced when a recent evaluation on bus operations involving priority signals (B‐signals) was undertaken in Singapore. This paper describes the difficulties faced when NETSIM was applied in modeling bus priority signals and the techniques adopted to overcome them. This study shows that, by incorporating innovative techniques, NETSIM can be effectively used to model bus operations along with other traffic in a network. 相似文献

A fair amount of literature pertaining to pedestrian streets has been produced but for the most part it is on the American and European developments. There has been surprisingly little published research on pedestrian street development in Asia. The purpose of this paper, therefore, is to examine pedestrian streets in Asia, using the city-state of Singapore as a case study. Since the mid-1980s, pedestrian streets have been adopted as a policy in the conservation and planning of Singapore's city centre. The resulting pedestrian streets came in many forms, from a single pedestrian-only street to a whole precinct of several streets. 相似文献
