Intersection Design Steps
There are four steps critical to the intersection improvement process -- be it a new intersection or an existing intersection in need of improvements. 1. Collect the necessary data (including vehicular and pedestrian traffic volumes, crash data, speed data, geometric field measurements) and observe vehicular behavior. In the case of a new intersection, use projected volumes.
2. Verify that existing and proposed traffic control devices conform with MUTCD standards. 3. Identify field constraints and hazards and determine how deficiencies can be corrected to safely and efficiently accommodate existing and future traffic. Finally, design intersection improvements using current design guidelines, standards, and local governing codes.
