Route Choice Characteristics of Owner-Operated Trucks in Southern California Freeways

The purpose of this research project is to evaluate the behaviors of owner-operated truck drivers to enhance decision-making regarding their route choices. The main objectives of this research are to estimate the value of time of owner-operated truck drivers' travel routes using the marginal rate of substitution method, and to evaluate its applicability in the economical feasibility study of a new road. The outcome of this research project is to produce a high quality field survey result on truck travel patterns. If awarded, the outcome will be of great interest to the state transportation agencies because it is very applicable to estimating the utility of a new road to trucks. The scope of this research is limited to Southern California freeways and also limited to the owner-operated trucks with drivers who make their own decisions when they choose the best routes. This project will address three main shortcomings in the current understanding of route choice characteristics of owner-operated trucks: First, the research team will compare the value of time by model type and truck size to examine if the average value of time can be applied as a representative value for all trucks. Second, the difference between the values of time calculated using the wage rate method and the marginal rate of substitution method will be evaluated. Finally, conduct an assessment using an economic feasibility study to examine the above effects. By addressing these issues, this project can complement the way a new project decisions are made, change the mindset of project participants, and ultimately aid in developing appropriate strategies and incentives for better managing shared systems. The owner-operated truck drivers' route choice preference models will provide alternatives that will allow agencies and truck operators to jointly make decisions based on a realistic common understanding of the effects and impact of route choice characteristics, resulting in decisions that are best for the economic feasibility study. The results will complement increasingly used marginal rate of substitution method, where both the wage of truck operators and the value of goods being transported are considered, and can have a great impact on the benefit/cost analysis in the transportation industry and the national economy.
