Linking Crash Patterns to ITS-Related Archived Data: Phase IIVolume II: Evaluations of ITS Strategies

In Volume I of the report models for assessing real-time crash risk were developed by analyzing freeway loop detector data corresponding to historical crash and non-crash cases. This volume (Volume II) of the report provides application of a subset of those models for evaluating ITS strategies in a simulation environment (PARAMICS) for their potential benefits in improving real-time safety on the I-4 corridor. It was found that under congested conditions Ramp Metering and/or Route Diversion can yield significant reduction in real-time crash risk while under free flow and conditions approaching congestion Variable Speed Limits may be more beneficial.
