To help avoid traffic congestion that causes long back-ups, sometimes forcing vehicles to block intersections well ahead of the one experiencing a jam, the traditional thought has always been to simply add more lanes and left-turn signals. And while this may work in many applications, in others they are often too expensive to employ due to the cost of obtaining the right-of-way or not the safest way to handle the situation, especially if the back-ups only occur twice per day.
By employing new methods of traffic simulation (micro-simulation), many of the traditional intersection back-up scenarios can be relieved with innovative intersection design. Essentially, an innovative intersection is an at-grade design that reduces the number of phases at the main intersection, resulting in increased capacity and efficiency of the intersection.
The most common intersection of this type is the roundabout. The use of this type of intersection has been around for a very long time, but by using today’s micro-simulation modeling, a better picture can be seen as to how it will increase traffic flow and what to expect in overall savings by eschewing traditional traffic signals.
But roundabouts are only one of a myriad of innovative intersections that are helping move today’s 21st century traffic more efficiently and safely. Find out why employing a dynamic and innovative design backed by a solid simulation may:
Provide a superior return on investment through a positive cost benefit ratio
Improved safety for pedestrians, bicyclists, and vehicles
Improved access management for businesses and residential property
Smaller impact on surrounding property areas
Possibility of avoiding additional lanes and traffic signals
