Slide 13: Step 3 Strategy Evaluation, cont’d.

Individual Corridor Analysis
CMP "Toolbox"
Area-Wide Mitigation Strategies
Corridor Solution Matrix
TIP Analysis

Strategy #1: Eliminate person trips or reduce VMT during peak hours. (Land Use, Congestion Pricing, TDM)
Strategy #2: Shift Trips from Automobile to Other Modes. (Transit, Bicycle and Pedestrian Improvements)
Strategy #3: Shift Trips from SOV to HOV Auto/Van. (Rideshare, HOV Facilities, Parking Management)
Strategy #4: Improve Roadway Operations. (Arterial and Intersection Operations, Access Management, ITS)
Strategy #5: Add Capacity

Current AADT
AADT Changes Since 1998
Truck Volumes along CMP Network
Transit Ridership Performance

Slide 19: Step 4 System Monitoring, cont'd.

Data Inventory:

Participation Data from TMA
ITS Infrastructure (Coord. Signals, Traffic Cameras, VMS)
Park & Ride / Park & Pool Inventory and Usage
Transit Ridership by Route and Capacity Analysis
Non-Motorized Facilities

Slide 20: How Has the CMS Helped Operations and Long-Range Planning?

Involve operating community in strategy selection process
Data collection / trend analysis of strategies
Transit Operations planning
Project prioritization for TIP & RTP
Assessing developer contributions for transportation Improvements

Slide 21: Transit Operations Planning

[Map highlighting CMS corridors and top, middle, and bottom performing transit segments for transit operations planning]

Slide 22: ITS Infrastructure

[Map identifying ITS infrastructure points (coordination signals, traffic cameras, VMS, TIAs etc.) and table showing growth in ITS infrastructure from 2003 to 2005.]

Slide 23: Park & Ride Facilities

[Map identifying areas with Park and Ride facilities.]

Slide 24: Assessing Developer Contributions for Transportation Improvements

[Map highlighting approved and pending development activity for New Castle County.]

Slide 25: How Has the CMS Helped Operations and Long-Range Planning?

Data Collection/Trend Analysis

Demonstrated need for better data collection

Travel Time data
Transit usage
Location of ITS infrastructure
Park & Ride/Park & Pool usage

Results:
- Funding set aside in UPWP for annual data collection
- Helps establish trends in measuring effectiveness of mitigation strategies/li>

Slide 26: How Has the CMS Helped Operations and Long-Range Planning?

CMP corridors used in TIP & RTP project prioritization
Scoring system gives higher priority to projects that have been recommended in the CMS

Slide 26: Project Prioritization Process
