Abstract:Maine has a data driven approach for HSIP project selection, assessing various aspects of crash performance. Before and After crash results comparisons on safety projects have consistently shown performance improvement over the years. HSIP selection process is re-evaluated each year to see if there are opportunities for enhancement and for improved alignment for the state's SHSP. Spot improvement project selection, particularly with regard to intersection safety, has been driven by HSM methodology this year, using our custom GIS intersection network screening process which computes excess crashes with EB adjustment for urban and rural stop and signal-controlled intersections on public highways in Maine regardless of jurisdiction. We continue to identify High Crash Locations each year as an additional consideration in prioritizing our spot improvement project candidates. We continue to work on collecting the necessary MIRE data elements to expand our network screening to highway segments. We are currently working towards obtaining cross slope information for the second lane of 2-lane rural highways using our ARAN 9000 by driving these roadways in the opposite direction of our normal pavement condition network collection activities as time and weather allows. We started the development of our custom GIS road segment screening tools that will assess the safety our highway network using excess crashes with EB adjustment in accordance with the HSM.
