As required by the FAST Act transportation performance management (TPM) initative, States must develop a listing of key truck bottlenecks. By definition, these are segment of roadway identified by the State DOT as having constraints that cause a significant impact on freight mobility and reliability. These bottlenecks are to be reported to the FHWA and are to be developed through data analysis, qualitative information, professional expertise and stakeholder engagement.
DelDOT, in coordination with the MPOs used a series of data layers as the criteria for selecting the truck bottlenecks. Those include:
- AM, PM and Summer Travel Time Reliability, which measures travel speeds during a given time of day vs. the overnight freeflow speeds
- High Truck Trip generation areas by Traffic Analysis Zone (TAZ)
- Daily truck volumes and percentages
- Existing roadway capacities (vehicles per hr.)
- Arterial intersections with high crash frequencies and severity
The map to the left contains all of these layers to allow users see the entire State conditions in relation to the identified truck bottlenecks.
