Corridor Traffic Management

When congested traffic conditions occur on one roadway, traffic on adjoining roadways or freeway interchanges in the corridor, are also impacted. Typically, as congestion occurs on one roadway, travelers respond in a variety of ways: finding an alternate route, selecting a different roadway (freeway versus surface street), adjusting their trip to another time of day, or remaining on their current route and enduring the significant delays. These disruptions range in scale, frequency, predictability, duration, and have the potential to impact a number of facilities or modes. A number of promising approaches may enhance how we currently operate the surface transportation system. The proactive use of managed lane strategies, alternate routing of traffic, and proactively managing and controlling traffic within freeway corridors offer are a few useful approaches. These strategies have the potential to achieve significantly greater levels of utilization of the existing roadway capacity, improve travel times, enhance safety, and reliability of travel.
