Abstract:
The Urban Mobility Report procedures give estimates of mobility at the area-wide level, describing congestion consistently by using generally available data and allowing for comparisons across urban areas or groups of such areas. The report procedures focus not only on projects that added lanes or reduced demand, but also on several other operational treatments and public transportation services. The report describes a framework for incorporating the operational treatments and shows the resulting effects.
The following six congestion reduction strategies were tested in 90 urban areas. Overall, these strategies lowered the freeway travel time index and freeway or arterial hours of delay:
- Freeway entrance ramp metering.
- Traffic signal coordination.
- Incident management programs.
- Access management programs.
- High-occupancy vehicle (HOV) lanes.
- Public transportation.
