Evaluating Alternative Operations Strategies to Improve Travel Time ...

SHRP 2 L11: Final Report
Table 6.14 Integration/Cooperation Strategies
Strategy Description/Application Modes Affected Impact on Reliability
Customized, real
time routing
Tuned to your preferences and driven by
real time congestion and reliability data,
with predictive capability. What will
conditions be when you get there?
Passenger
Vehicles/Freight/Transit
High
Multimodal
routing, schedules,
trip planning
Real time
information on
parking
availability,
roadway
conditions,
routing, rerouting
Gives people travel options. Same for
freight, though to a large degree this
exists for freight through 3PLs.
Time spent on parking will be significantly
reduced. Drivers will know where to find
parking available ahead of time.

Rapid incident
clearance
Automated scene assessment, damage
assessment through total stations and
digital imaging, rapid removal of damaged
vehicles. Ability to do on-scene accident
investigation in minutes, not hours with
automated imaging technology

Advanced
Automated Crash
Notification
Systems (AACN) in
all vehicles
Next Generation 9-
1-1 fully
implemented
Hybrid Wireless
Mesh Networks
Fleet turnover inertia overcome with
software upgrades rather than new
vehicle purchases
Passenger Vehicles,
Freight, Transit
Medium
Vastly improved transit as a serious option Transit Medium
Highly controlled to minimize transfer and
waiting time, elimination of dwell times
due to fare collection
Major elements self-monitoring on real
time basis. Reports problems in advance
Multiple information fusion methods
combine data from multiple sensors &
databases. Data fusion nodes
communicate on an ad hoc wireless
network.
Crash notification within one minute for all
crashes. Network of sensors in
infrastructure to detect imminent or actual
events or hazards
Full AACN telemetry data in actionable
form pushed into NG 911 system. Image
from inside vehicle automatically received
at PSAP after crash.
Mesh networks will facilitate the
communication of (VII) and improve
mobile interconnection. Vehicle-to-Vehicle
and Vehicle-to-Infrastructure networks will
be a reality.
