TRAFFIC LOAD FORECASTING IN TEXAS

An evaluation of the traffic load forecasting procedure used by the Transportation Planning Division (D-10) of the Texas State Department of Highways and Public Transportation (SDHPT) is presented in this report. Since any desired modifications to SDHPT's existing procedure are very dependent on the availability of vehicle classification and axle weight data, recommendations are made under two different scenarios: near-time (0-3 years) limitations, and long-term (3 years +) needs. Following a general summary of the importance attached to traffic load data, the report includes an overview of the significant findings of other traffic load-related studies performed in Texas. A detailed review of the traffic load forecasting procedures used in other states is also provided. The evaluation of the Texas procedure consists of a sensitivity analysis of its input parameters and a summary of the weight data collected in Texas. (Author)
