Abstract:

A model for prioritization of new proposed Environmental Sensor Station (ESS) sites is developed and presented in this paper. The model assesses the overall merit of a proposed ESS site as part of a Road Weather Information System (RWIS) using weather, traffic and safety data among other variables. Inputs to the overall merit model include weather index, traffic index, crash index, geographic coverage and opportunistic factors. The weather index at a proposed site is determined using multiple indicators of weather severity and variability. The crash index, another major input to the overall merit model, incorporates crash rate along the route and the percentage of weather related crashes over the analysis period. The traffic index, in turn, reflects the amount of travel on the highway network in the area surrounding the proposed ESS site. The fourth input to the merit model accounts for the ESS existing coverage in the area where the proposed site is located,while the fifth and last input is concerned with the availability and ease of access to power and communications. Model coefficients are represented by weights which reflect the contribution of each input (variable) to the overall merit of the ESS site. Those weights are user-specified and should be selected to reflect the agency preferences and priorities. The application of the proposed merit model is demonstrated using several selected sites in the state of Montana.
