Web-Based Pavement Performance and Maintenance Management and GIS Mapping System for Easy Access.

摘要

State Departments of Transportation, including the Texas Department of Transportation (TxDOT), have been moving towards the development and implementation of pavement management systems that would enable monitoring of the performance of their roadways, as well as assist transportation officials with maintenance budget allocation and planning decisions. Various attempts made in the past focused on using the available performance databases as well as state-of-the-art concepts for the development of such systems. The unique characteristics of Texas, the most prominent of which is the vast size of the managed pavement network 79,696 centerline miles of highways including 49,829 bridgeshave made some of the decision-support models and/or algorithms a challenge to implement. This report presents a new approach to the development of such a decision-support system with its focus on maintenance management for TxDOT. The new system is web-based and provides functional capabilities that allow transportation officials and engineers to make informed decisions regarding their budget planning and allocation for pavement maintenance management, fully utilizing available historical data. The developed system has been successfully pilot-tested in the Dallas District of TxDOT.
