Needs Analysis
Purpose and Need
- Conducted in accordance with PennDOT
Publication 319
- Developed based upon:
– Technical analysis – Public comment
- Basis of evaluation of alternatives
SLIDE 13
Needs Analysis
Purpose: To improve traffic flow, improve safety, and improve multimodal travel options in the Parkway East Corridor Transportation Network, located in Allegheny County, Pennsylvania, which consists of the Parkway East (I-376) from the Fort Pitt Bridge to the Pennsylvania Turnpike/US 22 interchange, and also includes parallel and intersecting arterial roadways.
SLIDE 14
Needs Analysis
Needs:
- The Parkway East is congested
- Alternate routes are congested
- Crash rates are above average
- Parkway East does not meet existing design
criteria
- Parkway East travel times are unreliable
- Multimodal transportation options are limited
SLIDE 15
MOEs
Measures of Effectiveness:
- Ways to measure how
improvements meet the goals of the project
- Evaluation of Cost, Benefits,
and Constraints
SLIDE 16
MOEs
Initial Screening:
- Qualitative
- Rank each MOE from 1-10
- Weight MOEs based on importance
- Identify fatal flaws
- Consider potential benefit-cost ratio
- Determine options to advance
SLIDE 17
Improvement Concepts
Improvement Concepts:
- Initial list of 100 based upon technical
evaluation and public input
- Screening to reduce number
- Some projects programmed
- Opportunities for early action
SLIDE 18
Improvement Concepts
Already Programmed:
- Queue detection on Glenwood ramp
- Glenwood off-ramp deceleration lane
- Second/Bates/Hot Metal signal retiming
- Bates Street Improvements
- Improve bottleneck on Route 28 at Highland
Park Bridge
SLIDE 19
Improvement Concepts
Review of Improvement Options:
- Six stations
- Conceptual at this stage
- Detailed analysis will follow
- Things we should know
- Anything we’ve missed
- Comment sheets
SLIDE 20
Project Approach
Next Steps:
- Preliminary screening
- Stakeholder email update
- Detailed Analysis
- Stakeholder Meeting #2
- Public Meeting
- Identify Potential Projects
- Implementation
