<strong>Operations</strong><br />
Performance<br />
Measures<br />
Communication mostly via pre-trip<br />
information such as:<br />
• Traffic reports (511)<br />
• Weather & road condition<br />
detection information mostly<br />
used for maintenance<br />
• Demand for information growing<br />
Isolated traffic management actions<br />
(lacks technical & institutional<br />
integration):<br />
• Roadside messages - DMS/VMS<br />
• Signal Retiming<br />
• Variable speed limits<br />
• Lane treatments (managed<br />
lanes, HOT, hard shoulder<br />
running)<br />
• Ramp metering<br />
• Service patrols<br />
• Electronic <strong>to</strong>ll collection<br />
• Transportation demand<br />
management<br />
Active Traffic Management<br />
deployed locally<br />
• Access management<br />
• Bottleneck removal<br />
• Alignment<br />
• Weaving<br />
Limited<br />
Very limited<br />
Communication expansion through widespread real-time<br />
traveler information<br />
Large scale information collection & dissemination<br />
delivered in advance <strong>to</strong> users in more accessible and<br />
usable forms including real time, predictive traffic<br />
information<br />
Sensor technologies and next generation road weather info<br />
systems used in traffic management strategies<br />
Integrated transportation operations<br />
Integrated Multimodal Corridors<br />
• Adaptive signal control<br />
• Freeway systems<br />
• Integrated ramp meters (network-wide)<br />
• Au<strong>to</strong>mated incident response (au<strong>to</strong>mated detection;<br />
rapid clearance using advanced technologies – data<br />
collection systems, fire suppression, medical treatment<br />
and vertical evacuation, on-scene traffic control)<br />
Innovative construction techniques <strong>to</strong> reduce impacts of<br />
construction (pre-fabrication, quick repair materials, selfrepair<br />
materials, embedded sensor that give early warning<br />
of infrastructure failures)<br />
Work zone management (real time traffic control,<br />
performance incentives)<br />
Pricing/congestion management<br />
Route/mode choice based on system optimization rather<br />
than solely user convenience, which can be done with<br />
pricing and will yield better overall solution<br />
Active Traffic Management with multi-agency and regional<br />
cooperation<br />
Advanced Transportation Au<strong>to</strong>mation Systems (au<strong>to</strong>mated<br />
limited access highways, au<strong>to</strong>mated truck-only highways,<br />
merger of truck and rail technologies, etc.)<br />
Optimized use of infrastructure and integration with land<br />
use development <strong>to</strong> minimize the need for spot geometric<br />
treatments<br />
• Load matching<br />
• Route Optimization<br />
• Traffic forecast by hour<br />
• Vehicle/driver inspection<br />
• Au<strong>to</strong>mated vehicle inspection<br />
• Weigh-in-Motion<br />
• Land use info<br />
Performance driven decision-making at the corridor and<br />
system level<br />
