Automating Web Collection and Validation of GPS Data for Longitudinal Urban Travel Studies

GPS-based travel surveys can avoid many problems of traditional paper and phone surveys and are becoming increasingly popular in major cities worldwide. We developed a Web GIS prototype in this project to collect GPS data from survey participants, detect travel modes and trip purposes, and allow survey participants to modify the results in a Web GIS.

Volume 2 - Load and Resistance Factor Rating (LRFR) in NYS

This report develops a Load and Resistance Factor Rating (NYS-LRFR) methodology for New York bridges. The methodology is applicable for the rating of existing bridges, the posting of under-strength bridges, and checking Permit trucks. The proposed LRFR methodology is calibrated to provide uniform reliability index values for all applications. The reliability calibration of live load factors is based on live load models developed using Truck Weigh-In-Motion (WIM) data collected from several representative New York sites.
