Abstract

The reports for calculating free flow and peaks were generated using a Traffic Master (from DfT) database that HCC has built in house.
Following on from this a calculation was then applied to both Free Flow and Peak datasets to establish the ratio against free flow speeds.
A check list is applied to determine whether a junction should be identified as a congestion hotspot.

This dataset shows the location of Congestion Hotspots based on junctions input file
