114492 | 422 Modeling & Corridor Analysis (Montgomery County)

As per PennDOT's suggestion and request, a PennDOT procured consultant is needed to assist with tasks which are outside of the scope of work and beyond the limits of DVRPC's resources. This entails conducting a thorough and comprehensive examination of the US 422 corridor. Work may include the impacts of additional impervious surfaces, stormwater management, socioeconomic impacts, and detailed cost estimates.
A consultant would assist with the detailed Vissim analysis and modeling efforts. DVRPC could oversee work that involves defining where Flex Lanes would begin and end by direction. Tasks could also focus on looking at opportunities where Flex Lanes may reduce the need for implementing the full programmed widening between PA 363 Trooper Road and US 202.
A consultant would assist in sensitivity testing for the operational impacts of this improvement strategy. It is likely that the Flex Lanes would operate with the use of ITS technology. This may include how the Lanes are opened and closed, hours of operation, and inner/outer lane configurations testing. Other ITS technologies, such as ramp metering, speed harmonization, dynamic lane assignment, and queue warning systems may also be explored.
For the transit component, consultant tasks may include developing preliminary BRT routes, schedules, station location, vehicle operations, system right-of-way, and potential ridership forecasts.
A consultant would prepare a comprehensive final report detailing findings and recommendations for all aspects of their work.
DVRPC's modeling work and deliverables would serve as an appendix to the larger report.
This approach would satisfy PennDot's request to look at the US 422 holistically and would set the foundation for implementation of the recommended improvements.
