Developing Solutions
With the technical data collection efforts complete and initial public feedback gathered, the project team has begun the challenging process of identifying potential multi-modal improvement concepts throughout the I-376 Parkway East Corridor Network. Stakeholder interviews, public meetings, and an online public survey generated hundreds of improvement concepts for the team to consider. Additionally, the team’s technical studies identified other safety, capacity, and multi-modal deficiencies to evaluate. With the project needs in mind, the team developed an initial list of 100 improvement concepts ranging from minor to major improvements. These preliminary improvement concepts were presented to the Stakeholder Committee in March of 2015 for review and comment (See the Stakeholder Committee page for more details).

Alternative Modes

Several of the concepts identified in the study area are already being pursued by PennDOT through other projects. These include:
•  Queue detection on Glenwood ramp
•  Glenwood off-ramp deceleration lane
•  Second/Bates/Hot Metal signal retiming
•  Bates Street Improvements, and
•  Improve bottleneck on Route 28 at Highland Park Bridge

The potential improvement concepts went through an initial, high-level screening, to determine which concepts will be advanced for detailed analysis. This screening evaluated the potential costs, benefits, and constraints to implement each concept, and looked for fatal flaws which would prevent a concept from moving forward. All improvement concepts were evaluated using a set of Measures of Effectiveness (MOE) which were developed by the project team. The Stakeholder Committee also had the opportunity to provide feedback regarding these MOEs.

The project team then scored each concept according to each MOE, weighted the different measures to reflect their relative importance, and developed an overall rating for each concept. Based on this rating, the preliminary improvement concepts were screened, reducing the list to a set of approximately 70 concepts that are being advanced for a more detailed analysis. This screening process and the alternatives being advanced are contained in the Phase 1 Alternatives Analysis Summary Report.

The alternatives that were recommended were then studied in more detail. This work included developing conceptual construction plans, estimating construction and operating costs, evaluating traffic impacts, and the potential benefits of the alternatives.
