Trip characteristics of travelers without vehicles

A knowledge of the rip characteristics of different groups of travelers in an urban area is of great use in planning land use and transport-related facilities. Travelers in households without vehicles (not even bicycles) make their trips either by walking or by using public transport. The mode choice of this group in Tiruchirapalli, Tamilnadu state, India is modeled for work trips using a binary logit model. Stratified mode-choice models are developed based on the location of the travelers' residence in relation to the central business district (CBD). The trip distance is identified as the major factor influencing mode choice. The critical trip length, which is defined as the limiting distance beyond which a traveler is not likely to make the journey on foot, is estimated for different subgroups of travelers using the probability models of mode choice. It is found that the acceptable walking distance for the different subgroups varies between 1.3 and 2.5 km.
