Abstract
Most American metropolitan areas are suffering highway congestion and delays. To improve the situation, alternatives other than increasing the supply part of transportation systems, such as telecommuting, have stimulated interest among planners and policy-makers. Research on telecommuting as one solution to reducing travel demand has been active in the past few years. However, most research focuses on analysis of the impact of telecommuting on vehicle-mobility rather than on individual accessibility. This paper attempts to evaluate telecommuting's effects on accessibility. A GIS-based case study for the city of Austin is presented to demonstrate the utility of GIS in accessibility measures. GIS serves as the data integrator, geo-computing, spatial analysis and mapping tool. Four simulations of telecommuting levels: a medium level and a high level in the base year 1997, and a medium level and a high level in the year 2025 are used to compare and analyze the different spatial patterns of the accessibility index.
