On average, drivers wait less than two minutes at ramp meters during peak hours.
Ramp meters are a proven and cost-effective method of relieving traffic congestion.
By increasing the efficiency of freeway use, ramp meters save taxpayers costs associated with building new lanes. Ramp meters are programmed to respond to actual freeway conditions. Using data from loop detectors, TSMC's central computers automatically calculate freeway and ramp congestion, and adjust the meters accordingly. At any time, TSMC staff may override the computers and manually operate the ramp meters if they see the need to.
