TACA Sim: a survey for adaptability assessment
Uncertainty of future fuel supplies and a requirement to reduce green house gas emissions are two pressures that may cause significant travel behavior change in the long-term. Understanding how people can change to carry out their activities without using a car; i.e. how adaptable they are, and how this adaptability depends on urban from, will aid local authorities planners and policy makers to develop transport systems and urban forms that are resilient to fuel shortages and high prices.This paper describes TACA Sim online travel survey in which one of the questions was “Could you get to the activity another way” The answer to this question for each trip taken was used to measure the adaptability of the survey participant. The results from a case study of two areas: the city of Christchurch and the small rural town of Oamaru showed that most participants did have another transport mode. Although participants were given the option of participating in the activity without travelling (i.e. working from home) this choice was not a popular alternative. From comparison between two groups, the surveyed group in Oamaru had a lower adaptability than the surveyed group in Christchurch, primarily due to the lack of public transport services in Oamaru. The results from this study are expected to contribute Oamaru authorities in improving local transport services and long-term planning for resilient urban form in the future.
