Development of Software for Spatially and Temporally Resolving Motor Vehicle Activity Data

摘要

The objective of this project is to develop a customized Geographic Information System (GIS) software application to spatially and temporally allocate Positioning System (GPS) instrumented vehicle activity data and provide summary statistics at a range of spatial and temporal resolutions. Major research activities were made in three areas: (1) correct translation of vehicle location data into meaningful routing information necessary for construction of trip patterns, (2) effective organization of both digital street maps and vehicle data in a comprehensive database required for compilation of critical statistics for analysis of mobile source emissions at desirable geographic configurations, and (3) incorporation of mapping and database management capabilities into a user-friendly, automated procedure suitable for analysis of the spatially and temporally resolved motor vehicle activity based on the huge volumes of GPS-instrumented vehicle data. A analytical application is built on ESRI's ArcView GIS for ARB researchers to carry out a wide range of motor vehicle travel data analyses.
