15.2.1 Supply Strategies
Key supply strategies include:
Identifying incidents more quickly, reducing response times, and clearing
incident scenes more rapidly will dramatically reduce incident delays
—
espe-
cially in peak hours.
Stationing of response vehicles at strategic locations to minimize the time
needed to remove incidents
Training emergency responders with practices that minimize their presence at
the incident site
Providing traveler information to divert traf
c away from the incident location.
Incident response performance can be improved and response times reduced by
widespread deployment of surveillance and detection technologies.
15.2.2 Demand Reduction Strategies
Demand reduction strategies include:
diverting traf
c away from incident bottlenecks by:
providing real-time information to drivers on incident locations and con-
gested roadways and
-
-
advising travelers of available alternative routes.
Closing on-ramp to prevent additional
traf
c from entering the congested
highway section
Advance variable message signs along freeways can help to divert motorists
away from congested roads impacted by an incident.
15.3 Special Events
Special events account for up to 5 % of congestion delay [
3
].
Special events (e.g., conventions, football games) are time and location-speci
c.
Ideally the starting and ending times of these events should be scheduled outside
the peak travel hours.
