Guide for Geometric Design and Operational Factors That Impact Truck Use of Toll Roads

15. Supplementary Notes Project performed in cooperation with the Texas Department of Transportation and the Federal Highway Administration. Project Title: Operational Factors that Impact Truck Use of Toll Roads URL: http://tti.tamu.edu/documents/0-5377-1.pdf 16. Abstract This purpose of this project was to identify the potential factors that could impact truck use of toll roads or managed lanes. The researchers outlined the trucking and freight industry needs through synthesis of existing literature. Identification of geometric and operating factors that are important to truck drivers and operators in terms of safety and efficiency will better characterize what makes toll roads attractive to those users. The factors are organized around industry needs (e.g., safety, travel reliability), facility design characteristics (e.g., access, ramp design, system connectivity), operating characteristics (e.g., signing and pavement markings), and corridor operating characteristics (e.g., traffic, congestion). The research resulted in published guidelines to help transportation planners, highway designers, and transportation operations professionals determine the geometric design and operational factors important to attract the trucking and freight industry to toll roads. The research was done through known relationships of design, safety, and operations.
