Those entering vehicles in turn back up and block the exiting vehicles. Traffic exiting the highway may back up and block the entering vehicles. Īnother type of gridlock can occur during traffic surges between highway on-ramps and off-ramps located within a quarter mile of each other. If all drivers follow this rule, gridlock is impossible. In many jurisdictions, drivers are therefore prohibited from entering an intersection at a green light if there is no room for them to clear the intersection. If the same situation occurs simultaneously in multiple intersections, these cars can be trapped in the intersections indefinitely. This can lead to the car being trapped in the intersection when the light turns green in the other direction. Traditional gridlock is caused by cars entering an intersection on a green light without enough room on the other side of the intersection at the time of entering to go all the way through. Lights are green but backups fill all the space. Vehicles on three lanes blocking each others way. By extension, the term has been applied to situations in other fields where flow is stalled by excess demand, or in which competing interests prevent progress.Ĭause Gridlock on Kaiser-Friedrich-Ring, Wiesbaden, Germany. The term Gridlock is also used incorrectly to describe high traffic congestion with minimal flow (which is simply a traffic jam), where a blocked grid system is not involved. The term originates from a situation possible in a grid plan where intersections are blocked, preventing vehicles from either moving forwards through the intersection or backing up to an upstream intersection. Gridlock is a form of traffic congestion where "continuous queues of vehicles block an entire network of intersecting streets, bringing traffic in all directions to a complete standstill". The red cars are those causing the gridlock by stopping in the middle of the intersection. Gridlock on a network of two-way streets. For other uses, see Gridlock (disambiguation).
