Improvements on Automated Routing of Overweight/Oversize Vehicles

摘要

Improvements of GIS Software to perform automated routing of overweight/oversizevehicles for the Texas Department of Transportation are reported. Originally developed in Texas Department of Transportation (TxDOT) Research Study 0-1482, the software was incorporated with functional improvements to consider vehicle turn penalties, to obtain maximal-capacity routes and to speed up the computation process in determining routes by network partitioning. Also included in this report are (a) the description of the procedure to update the GIS information due to periodic changes in the BRINSAP database, and the geographic features of the On-system Highways of Texas as documented in digitized county maps; (b) a summary of observations made during the correction and verification of the bridge locations for all On-system bridges in Texas; and (c) installation and user's guides manual of the routing software. The software is intended to be used by the Motor Carrier Division (MCD) and the Design Division of TxDOT for the evaluation of bridges and clearances along routes of superheavy-vehicles.
