Traveler information has long been a management and operations strategy for transportation agencies. Used to inform travelers of events that may impact their trips, traveler information services have evolved considerably since the national designation of 511 in 2000. ENTERPRISE initiated this project to review the current state of traveler information practice for reporting road weather events and to explore the possibility of creating a community of practice and providing guidance on future practices. This project builds off recent work completed by ENTERPRISE that researched how agencies are automating the process of reporting winter road weather conditions. It will also revisit previous work on the next era of traveler information.
Wrong-way driving is a growing concern on roadways, especially because resulting crashes tend to be severe and often result in fatalities and serious injuries. Transportation agencies are deploying on-road countermeasures at select locations; however, these can only go so far to reduce wrong-way crashes. In-vehicle navigation systems and mobile applications hold significant potential to reduce wrong-way crashes. These interventions could reach many more drivers than on-road countermeasures alone, by providing alerts at all times and all locations while the application is being used. The ENTERPRISE Pooled Fund is conducting outreach to automobile manufacturers and mobile app developers to explore the potential for in-vehicle navigation systems and mobile apps to provide wrong-way driving alerts.
This ENTERPRISE Pooled Fund Study project will capture insights from agencies that have conducted automated vehicle (AV) shuttle demonstrations and identify likely impacts of AVs on infrastructure operations. Specifically, this effort focuses on low-speed AV shuttles with the intent to understand whether infrastructure changes and the roles of agency and private-sector stakeholders are representative of needs and roles in future, long-term AV deployments. Information will be collected through a literature review and interviews with 12 deploying agencies in the United States and Canada. Identified impacts to agency infrastructure and staff vary greatly depending on the use case and AV shuttle provider. The types of infrastructure changes for AV shuttle deployments include pavement markings, signage, roadside units, traffic signal timing adjustments, charging stations, secured parking areas, and vegetation management, as well as modifications to construction schedules. The nature of these impacts will be considered, as well as the reasons these impacts may be greater for some agencies than others.
