Abstract:
Managed lane networks are complex, interconnected facilities that require advancements in traveler information to successfully serve the users of those facilities. Historically, these lanes were developed for single, district corridors and provided preferential access for users traveling from one endpoint to another. Their success led later to planned, constructed networks of managed lanes that expand the concept across most major freeways within a region. Operators currently rely mostly on signage, websites, and social media to convey information on pricing and operating rules. However, existing communication methods will become ineffective as network complexity increases. New technology, including advancements in traveler information and connected vehicles, may be a possible solution.
For this research project, researchers conducted (1) a national state-of-the-practice review; (2) system user focus groups and surveys; and (3) an assessment of emerging technologies.They found that managed lane networks nationwide differed considerably in type of pricing structure,number of priced destinations on signs, and availablility of toll information. A travel survey of 866 Texas respondents showed that drivers prioritize information about traffic accidents and lane closures over price data.
Researchers recommend a pathway for agencies to share essential data with third-party entities, based off the general transit feed specification (GTFS) used for transit. The GTFS-based approach limits the operating agency to manage the outflow of critical data, while not endorsing a specific medium that can easily change relevance. A key implementation challenge is the coordination between agencies to agree on a common framework for providing both static and dynamic information. Agencies might consider the relative basic elements of priced managed lane data as a precursor for developing platforms to support automated and connected vehicle applications.
