Summary
This report documents the development and application of a standardized evaluation framework for Advanced Traveler Information Systems (ATIS) within Washington State. The research was motivated by federal requirements for local self-evaluations of Intelligent Transportation System (ITS) deployments and a broader need to support the "mainstreaming" of ITS into normal transportation investment processes. The primary objectives were to create a straightforward evaluation process, gather lessons learned for future deployments, and explore methods for quantifying system benefits. The study assessed five specific ATIS projects funded in FY 1999: the Edmonds Ferry Terminal, State Route (SR) 101, SR 2 and SR 97 mountain passes, SR 395 freight corridor, and the Tacoma Traffic Management Center (TMC) enhancement. The methodology comprised two components: a qualitative "lessons learned" framework and a quantitative benefit estimation approach. The qualitative framework reviewed project planning, design, construction, and operations and maintenance (O&M) through stakeholder interviews and document reviews. The quantitative component aimed to estimate benefits to support investment decision-making, addressing the historical difficulty of measuring direct safety and mobility gains. Individual project reports analyzed system features, O&M procedures, public response, and management issues. The Edmonds Ferry Terminal project utilized Variable Message Signs (VMS) and web cameras to provide ferry delay and queue information. Operations were managed by the Washington State Ferries (WSF) Traffic Operations Center, with maintenance handled by WSDOT under a successful O&M agreement. The system improved terminal operations and customer service, with independent evaluations confirming public utility. However, challenges included technical incompatibilities with consultant-designed equipment and cumbersome message verification processes. The SR 101 project targeted recreational travelers on the Olympic Peninsula, deploying Road Weather Information Systems (RWIS), cameras, and Highway Advisory Radio (HAR) to provide traffic and weather data. The project aimed to manage traffic and promote tourism, with phased implementation to maximize budget efficiency. Across all projects, significant lessons were identified regarding maintenance, project management, and institutional coordination. Maintenance staff emphasized the need for early involvement in design to ensure compatibility with existing technology and adequate spare parts. The report highlighted that rural deployments and multi-agency projects require robust communication channels and clear role definitions. For instance, the Edmonds project demonstrated the value of partnerships between WSDOT and WSF, while also revealing conflicts with local city councils regarding infrastructure changes. The Tacoma TMC enhancement focused on installing fiber optic links to improve data transmission capabilities. The study concludes that a standardized evaluation framework can effectively capture technical and institutional insights from ATIS deployments. The findings provide guidelines for planning and operating ATIS systems, emphasizing the importance of integrating maintenance considerations during the design phase and fostering strong agency coordination. By documenting these lessons and exploring benefit quantification methods, the report supports the broader adoption of ITS technologies by providing evidence-based strategies for future investments and operational improvements.
Key finding
Lack of coordination between design consultants and maintenance staff resulted in incompatible equipment and increased repair costs, whereas projects with early maintenance involvement demonstrated smoother operations.
