Abstract:

In this paper, the authors have conducted a spatial analysis of roadside devices for potential vehicle-to-infrastructure (V2I) adaption using geographic information systems (GIS) to assess: 1) the road network covered by potential future V2I installations at existing roadside devices; 2) the vehicle miles traveled (VMT) by those potential installations; 3) the number of safety priority index system (SPIS) sites within the range of those potential installations; and 4) a priority list of roadside devices for V2I equipment installation that provides Oregon Department of Transportation (ODOT) with the maximum benefit-cost ratio. This research is part of a larger study aiming to assess Oregon’s state-level V2I deployment readiness for connected vehicle applications. The assessment is accomplished by fully leveraging ODOT’s existing roadside devices with electrical power and communication components as potential deployment locations, thus reducing the cost and accelerate the speed of installation. In addition, the spatial analysis for equally spaced roadside equipment (RSEs) along Oregon’s highway network is required to determine the necessary number of RSEs to provide sufficient coverage along the state highway network. Considering the benefits of both usage (highway mileage and VMT) and safety (SPIS), the results show that ODOT can first deploy V2I equipment at sites where existing ITS devices are located, which covers the largest extent (highway mileage), VMT, and SPIS coverage compared to other types of roadside devices. Other state DOTs and transportation agencies will benefit from this methodology to assess their readiness for V2I deployment.
