Rassam et al. [2] analyzed the significance of access and egress modes on the main mode choice by using analytical estimation processes. Two models for estimating transit access characteristics were developed. The first model estimated the average access walking distance, assuming an average walking speed, therefore indirectly providing walking time. In this model, walking distances were considered as being exponentially distributed. A walking versus automobile diversion curve was developed and analyzed for various socioeconomic and modal characteristics
