Speaking

The Clark County-Springfield Transportation Coordinating Committee (CCSTCC) sought to identify locations where single-lane roundabouts would improve safety, efficiency and mobility across Clark County, Ohio. This presentation will share how through the use of a statistical methodology and publicly available GIS data, the team created a list of key screening criteria and a weighted ranking to analyze a majority of the intersections across the county. This dynamically weighted system allowed the team to create different priority scenarios and see in real time intersections that continually come to the top of the list regardless of the scenario.

Public feedback captured through an interactive ESRI webpage and survey provided additional data points to identify intersections for roundabouts. The team narrowed over 5,000 intersections down to a prioritized "Top 50" list of intersections to consider for improvements. After a dashboard review and input from a core stakeholder group, preliminary layouts at the top 14 locations were developed to provide costs and confirm implementation feasibility.

Given the high injury severity experienced with wrong-way crashes, eliminating just one crash could likely save a life. Wrong-way detection is an excellent systemic approach that can be applied to individual locations or entire corridors. 

Burgess & Niple will present on the Loop 303 Freeway Management System project in Phoenix, Arizona. This TSMO project started out to add ramp metering, CCTV monitoring, and dynamic message signs to a 6-mile freeway. During the process we realized that with all this ITS infrastructure in place, a wrong-way driver detection system could be added to the corridor with a minimal investment. This presentation will explore key considerations in designing the Arizona system, including the technology used and the chain of events set in motion when a wrong way driver is detected. Additionally, other technology that could be implemented, including camera types, signing options and communications at locations without a robust communication and ITS infrastructure will be discussed. Considerations for urban and rural locations will be presented as these locations have very different site characteristics.
