Summary

This report, commissioned by the Texas Department of Transportation (TxDOT) and conducted by the Center for Transportation Research at the University of Texas at Austin, addresses the growing necessity for Electronic Vehicle Identification (EVI) as road pricing supplants gas taxes for transportation funding. The research was motivated by the need to improve the efficiency of Electronic Toll Collection (ETC) and enable broader Intelligent Transportation Systems (ITS) applications, such as vehicle-roadside communication. The study focused on three primary areas: evaluating current and emerging vehicle identification technologies, integrating national and state standards with legislative and public considerations, and analyzing the costs, benefits, and implementation requirements for universal EVI. The researchers employed a comprehensive approach involving nine distinct tasks. They established an expert panel from the toll-road and ITS industries to guide the research, reviewed over 100 documents on tolling and ITS developments, and conducted interviews with TxDOT staff and other agencies. The methodology included synthesizing best practices in toll collection, developing a technology matrix timeline projecting developments through 2020, and analyzing the performance, accuracy, and cost of various ETC technologies. Additionally, the team assessed organizational requirements for linking tolling databases with vehicle registration records, conducted a cost-benefit analysis under various deployment scenarios, and reviewed legislative needs regarding data privacy and collection policies. Key findings highlight that while ETC is the preferred practice for tolling, non-account vehicles still rely on video tolling, which is more expensive and prone to errors compared to transponder-based systems. The report identifies Dedicated Short Range Communications (DSRC) as a critical standard for EVI and outlines the evolution of tolling from corridor-based systems to more complex area-wide mileage tolling and integrated system management. The cost-benefit analysis provided specific estimates for statewide and corridor-specific implementations, demonstrating the economic viability of EVI. The study also identified significant privacy concerns and the need for clear policies on data collection, sharing, and permissible uses to ensure public acceptance. The significance of this work lies in its provision of a strategic roadmap for TxDOT to implement universal EVI. The report concludes with an outline business model for EVI implementation, recommendations for legislative action, and a timeline for technological adoption. By addressing the technical, organizational, and economic dimensions of EVI, the study supports the transition toward more efficient tolling systems and advanced ITS features, ultimately aiming to enhance transportation system management and funding mechanisms in Texas and potentially beyond.

Key finding

Electronic toll collection using transponders is significantly more cost-effective and efficient than video tolling, with transaction costs of 10-20 cents compared to $2.25 per transaction for license plate recognition.
