Establish an accident database with the location,
time, nature, and cause of accidents as well as the traffic conditions
in which they occurred.
Rear end collisions
- Consider signal
coordination to reduce sudden stops.
- Consider variable message signs triggered by traffic
occupancy to warn of slow or stopped traffic ahead. Ê
Intersection collisions
- At signalized intersections, consider signal
coordination or video
red light monitoring to reduce incentives to run red lights.
- For collisions due to vehicles crossing a busy street,
consider installing an actuated
signal that is green for arterial traffic except when actuated
by cross traffic.Ê
- At un-signalized intersections with repeated accidents,
consider speed sensors and warning signs for vehicles approaching
too rapidly.
Rail crossing collisions
Single car accidents
- In locations where excessive speed causes accidents
consider:
- variable message signs that show safe speeds under
current conditions
- sensors that detect vehicle speeds
- a sign that both displays each vehicle's speed as
it approaches andÊ issues a warning if the speed is excessive
- video cameras that record license numbers of vehicles
that are exceeding the speed limit
Bicycle and pedestrian accidents
- To avoid bicycle accidents at signalized intersections
with high bicycle traffic, consider bicycle-actuated signals.
- To avoid pedestrian accidents, consider pedestrian-activated
signals, countdown signals for crossings that span wide streets,
and crosswalks with ground-level lights that go on when pedestrians
are crossing.
