Web-Based Routing Assistance Tool to Reduce Pavement Damage by Overweight and Oversize Vehicles

Abstract

This report documents the results of a completed project titled "Web-Based Routing Assistance Tool to Reduce Pavement Damage by Overweight and Oversize Vehicles". The tasks involved developing a Web-based GIS routing assistance tool and evaluate the impact of OS/OW loads to highway pavements.The objectives of this project are: (1) to analyze historical data with respect to the dimension and weight of the OW/OS vehicles, their origin and destination, permitted routes, and frequency of the routes; (2) to develop an electronic Origin Destination (OD) Matrix and a digitalized region-wide Route Map on the basis of historical records; (3) to determine thresholds and design criteria for accommodating OW/OS vehicles and super-heavy loads; (4) to develop a desktop-based tool with integrated pavement and routing information; (5) to develop a web-based tool with integrated pavement and routing information; and (6)to develop pavement performance models by using the collected pavement condition data, traffic data, OW/OS vehicle data and environment data. The product of this project will provide guidance on the criteria to design and maintain highway structure and pavement. The pavement performance models have laid a basis for other similar projects, i.e., developing an optimal routing algorithm to significantly reduce road damage from OS/OW vehicles. In addition, the web-based routing system provides valuable lessons for other states that are looking for such a website to solve OS/OW vehicles routing issues.
