were identified, individual police reports for those locations were requested from the
MaineDOT and collision diagrams were prepared. The collision diagrams were then
examined to identify whether there are patterns that can be corrected.
Figure 2-5 and Tables 2.2-4 and 2.2-5 summarize the HCLs for the Study Area
intersections and roadway segments as established using the MaineDOT criteria.
When a node is identified with the prefix “P”, it means that it was in proximity to an
adjacent node and, for the purposes of crash reporting, the MaineDOT considers the
two nodes as a single node. The tables also identify how many police reports were
actually provided by the MaineDOT for that location. Occasionally, there are
discrepancies between what is originally reported in the summary sheets and the
actual number of police reports. This occurs because as the police reports are pulled,
miscodings made on the originals are identified and adjusted as needed. The most
substantial change for this Study Area is Node 13637, which is identified in the
summary sheets as having eight crashes and a CRF of 1.06, thus making it a HCL.
According to the MaineDOT, there were numerous miscodings for this node and the
actual number of police reports is three. Because there were only three reports, Node
13637 was not listed in the summary tables.
