In Espanola, New Mexico the implementation of a traffic management system on NM 68 provided a decrease in total crashes of 27.5 percent and a reduction in vehicle delay of 87.5 percent.
Prior to signal system improvements, the eight project intersections operated independently. Before/after data collection and analysis was performed for evaluation purposes. After the system was deployed , in 2006, the traffic management system benefits included:
- a decrease of 27.5 percent in total crashes compared with previous years.
- a reduction in vehicle delay of 87.5 percent, improving the level of service (LOS) on NM 68 from a LOS F to a LOS A.
