Summary
This report synthesizes the current state and future trajectory of Kentucky’s traveler information systems, specifically focusing on the 511 program mandated by the Federal Highway Administration. The study was motivated by the need to benchmark Kentucky Transportation Cabinet (KYTC) operations against federal requirements and evolving user behaviors. While the 511 dialing code was established in 2000 to reduce congestion and improve safety, usage patterns have shifted dramatically. The research aims to inform decision-making regarding the future of these systems by analyzing current operations, stakeholder perspectives, driver preferences, and comparative practices in other states. The methodology involved a multi-faceted approach: reviewing KYTC’s 511 usage data (phone calls, website visits, and app usage) from 2011–2014; conducting interviews with KYTC stakeholders to assess system strengths and weaknesses; comparing third-party applications (Google Maps, Waze, Beat the Traffic, Inrix, Here) with state-provided tools; analyzing survey data from Kentucky drivers regarding their preferred information sources; and interviewing representatives from other state DOTs (Florida, Iowa, Montana, Utah) to identify exemplary practices. Key findings indicate a sharp decline in 511 phone call volumes since the mid-2000s, while traffic on KYTC’s websites and mobile apps has increased, particularly during winter months. Stakeholders agreed that while the phone system remains necessary for rural areas, its relevance is diminishing. A significant finding is that government-provided services (511, TRIMARC) are not the primary source of traffic information for drivers; only 13% cited them as their most trusted source, compared to the majority who rely on digital providers like Google Maps and Waze. However, television and radio remain critical for hazardous weather updates. The study also noted that while third-party apps are popular, they often lack the detailed incident reporting and winter condition data provided by KYTC’s systems. Stakeholders identified challenges including manual data entry delays and the need for better performance metrics, particularly for partnerships like the one with Waze. The significance of this research lies in its confirmation that state DOTs must adapt to a landscape where private sector providers dominate user engagement. While there is consensus that DOTs must continue to provide authoritative data, the delivery model is uncertain. The report suggests that states are retooling their digital platforms over the next 2–3 years and increasingly relying on public-private partnerships. It highlights a paradox where states view third-party providers as both competitors and essential partners for reaching the public. The findings imply that future strategies must focus on integrating state data into popular third-party platforms, improving real-time data distribution, and developing robust marketing and performance measurement strategies to maintain the value of public traveler information systems.
Key finding
Only 13 percent of Kentucky drivers identified government services as their most trusted source for traffic information, while the majority preferred digital content providers like Google Maps and Waze.
