The FHWA performed a comparative analysis on data collected along State Route 6 corridor in Houston before and after the activation of the ACS Lite. Metrics studied included speed, travel time, delay, number of stops and fuel consumption.
Methodology:
Results:
Methodology:
- Collect ‘before’ and ‘after’ traffic volume machine counts on State Route 6 (SR 6)–eight intersections
- Perform ‘before’ and ‘after’ floating car travel time and delay studies along SR 6 – eight intersections
- Perform statistical analysis on ‘before’ and ‘after’ traffic volumes, speed and travel time and delay data
Results:
- Total delay, number of stops and fuel consumption all decreased when ACS Lite software was in effect
- There would be an annual savings of $578,000 due to these improvements.
Before (per veh) | After (per veh) | Savings (per veh) | Peak Hours (per veh) | Peak Hours Savings | |
Total Delay (hour) | 0.01856 | 0.01214 | 0.00642 | 39.16252 | $474 |
