Definition of One Way Traffic Spikes: (The following definition in quotes is copyright protected.)
“"one way traffic spikes” - noun; plural
1: mechanical pivoting spikes in a roadway that can yield downward to vehicles for allowing movement in only one direction

  • one way traffic spikes direct traffic through payment stations for revenue
  • a parking lot uses one way traffic spikes to control traffic flow.
  • Drive across the one way traffic spikes to enter the parking garage.

2: mechanical pivoting spikes in a roadway that can remain upward to prevent vehicles from movement in an improper direction

  • “Do not enter an exit lane that has one way traffic spikes across its surface; the tires could become damaged.””

One way traffic spikes are used to create a direction of travel in a single, or one, direction. One way lanes facilitate one way traffic, directing vehicles to cross in one direction. One way traffic spikes typically result in higher traffic flows as drivers are able to avoid oncoming traffic or crossing and merging into oncoming traffic.
Examples of one way traffic spikes systems in use:

  • Narrow lanes hamper the safety of movement in dual directions.
  • Design of paid parking or controlled vehicle accessibility.
  • Slower speeds.
  • Reductions in Congestion of traffic.
  • Security and safety for personnel and property.

Vehicles traveling the wrong direction on one way freeways has been a traffic safety issue since the interstate highway system was created prior to the 1960s. The vast majority of wrong-way drivers turn around and drive back into the correct direction. Some drivers, even though they are not intoxicated, do continue to drive the wrong way on a one way thoroughfare. Many civilians think that spikes can be a cure to preventing wrong way travel, but these systems are not designed for repeated, high speed impacts. We can develop a system that can work, but it would require about $10 million in research and development to design a computerized system. Such one way traffic spike systems would be very expensive to install at each traffic access point, costing approximately $2 million per use/area.

Approximately 360 people are killed annually in wrong way highway crashes, with thousands more being injured. Some states take additional actions to improve entry and exit designs, signage, and striping to prevent wrong way accidents. Some states are researching intelligent transportation system technology to track directional violations. Other systems use embedded sensors, flashing lights, and recording equipment to see how a driver became involved in traveling the wrong way in a one way traffic environment.
