Monitor Traffic Conditions before and afterTravel Time Runs

• Travel time runs on Green River Road and SR 91 (3 days/ week)

• Traffic counts on SR 91 and Green River Road

11

Monitor Traffic Conditions before and afterVideo Camera Observations

2 cars per green: Compliance Statistics

• One-third of the time only 1 car left the meter

• Ramp throughput and travel time on Green River Road degraded
