Understanding Transit Ridership Demand for the Multidestination, Multimodal Transit Network in Atlanta, Georgia: Lessons for Increasing Rail Transit Choice Ridership while Maintaining Transit Dependent Bus Ridership
分析了亚特兰大公交系统中巴士和铁路乘客的不同需求特征，发现巴士乘客来自低收入地区且对时间敏感，铁路乘客重视快速直达就业中心，为提升两类乘客量提供了策略建议。
This study analyses the structure of transit demand in Atlanta’s transit system to understand why different elements of the network appeal to bus and rail riders. By estimating direct demand models of work trip use between pairs of traffic analysis zones, the authors find that self-identified bus riders come from poorer areas having fewer autos per household and seek to reach jobs scattered throughout the metropolitan area. Their demand is highly elastic with respect to travel time. They care not about the presence of transit-oriented development (TOD) attributes at either origins or destinations. Self-identified rail riders primarily access transit by automobile and value fast service to within convenient walking distance of employment, such as in the central business district (CBD) and some but not all TODs. The results suggest that an agency could increase ridership by both groups using a core network of higher speed lines that provide access to decentralised employment centres.
