SLIDE 3
- Step 2 in the process
is to define the study area
- Step 3 in the process
is to define the network

SLIDE 8
Prioritized Locations
Multiple criteria went into identifying the intersections and segments:
- Safety
- Delay
- Reliability
- Presence of existing ITS
infrastructure
SLIDE 9
- Existing infrastructure
- Existing projects (planned
- r programmed)

SLIDE 10
Monitoring Strategy Effectiveness
- Mobility measures
- Collecting data
- Device deployment
- Before & After studies
SLIDE 11
Recommendations
Add CMP projects to Project Priority List Implement CMP projects Assess the efficiency and effectiveness of CMP projects
SLIDE 12
Performance Measures
ATMS project Identification
Top 25% or 35 unique segments
Safety Delay Level of Travel Time Reliability
(LOTTR)
Truck Travel Time Reliability (TTTR) ITS
Significance Length of segment (longer segments, higher priority)
SLIDE 13
Top 25% or 35 unique segments
- Approximately 90 miles in corridors
- 20 miles on I-75
- Minimum corridor length was 0.25 mi
- Maximum corridor length was 12.25 mi
- Two or more performance measures
triggered by top corridors
- 2 corridors had 4 performance measures identified
- 15 corridors had 3 performance measures identified
SLIDE 14
Top 25% or 35 unique segments
- Arterial and freeway mitigation strategies
are needed
- Mitigation strategies identified to target
location specific performance:
- Ramp Metering
- Incident Response Vehicles
- Managed Lanes
- Traveler Information
- Variable Speed Limits
- Adaptive Signal Control
- Arterial Management
- Instrument Deployment
SLIDE 15
Countywide or regionwide strategies
- Some strategies are to be
deployed as a region or countywide rather than corridor specific:
- Incident Response Vehicles -
$2,500,000
- Managed Lanes - TBD
- Traveler Information - TBD

Additional
- pportunities
to expand ATMS strategies
- Delay Significance (HERE Data, Peak
Hour, Daily Delay)
- Level of Travel Time Reliability
Significance (non-reliable segments)
- Truck Delay Significance (NPMDRS)
