Project Summary
The Institute of Transportation Studies at the University of California, Irvine, has recently developed for ARB a tool that merges data from different data sources related to roadway vehicle activity. The predominant sources of data are the Weigh in Motion (WIM) system and the Vehicle Detection Sytem (VDS). These data sources produce huge volumes of data from detectors scattered throughout the state. The tool developed pulls in data from both of these sources and merges these sets based on time, geographic proximity, and statistical imputation techniques. The purpose of this proposal is to complete the project. There is still a small amount of work remaining in the development of the web-based graphic user interface, some work left on the data fusion task, and finally the important training and documentation tasks. The work proposed here is within the scope of the original proposal, and the total budget requested does not exceed the amount remaining from the original contract.
