Understanding the influence of roadway configuration on traffic flows through a conventional traffic-assignment model

Abstract

Abstract Space syntax researchers have found that the role of roadway configuration itself is apparent in influencing urban movement. Despite this important finding, conventional traffic-assignment models are not seen to take the configurational measures into account for modeling urban movement networks. The argument is where exactly is the short fall in understanding the influence of roadway configuration on the urban phenomena of trip-making and route choice from the conventional traffic-assignment stance? This paper throws deeper insights into this question and reports the progress in the area of transportation planning research by producing theoretical evidence showing that configurational influence on urban movement gets captured through the capacity-restrained-analysis model-one of the prevalent trafficassignment models adopted by the transportation planning community. The conclusion reinforces the syntax research finding explaining that topological complexities of urban textures significantly get involved in modeling urban movement networks much of which has not been addressed before in the conventional traffic-assignment models.
