Device name(s): Intersection Geometry Changes
Approximate Cost:
Definition: Intersection geometry changes introduced traffic modification and control through channeling, redirection, and tightening turn radii. Proper design can reduce aggressive driver action and calmer traffic. Intersection geometry changes may incorporate several other measures to achieve the requested result.
Fast Facts:
- Can be used on Local Street-
- Can be used on Collector-
- Can be used on Arterial-
- Reduces Speed-possible
- Reduces Volume- possible
- Noise Impact- no
- Restricts Access- no
- Bicyclist Impact- possible
- Transit Impact- possible
- Parking Impact- possible
- Emergency Response Impact- possible
Advantages:
- reduces aggressive driver incident/accident potential
- improves pedestrian safety
- can be used to narrow excessively wide intersections
- slows turning traffic
Disadvantages:
- may reduce on-street parking
- can be expensive if utility work is required
Criteria/Application(s):
- 85th percentile speed is 5 mph above the speed limit or greater
