Smart Multi-modal Transportation Solution for North Huntingdon Township in Response to Roadway Construction Projects on Route-30

Route 30 in the North Huntingdon Township serves as a main commercial corridor as well as a regional arterial. Part of a growing area, there are significant challenges with congestion, safety, travel demand and mobility. There is a great need to provide a holistic mobility solution including driving, transit usage, park and ride lots, and existing and projected land use development. This corridor offers all of the challenges to developing a transportation corridor multi-modal plan. In addition, PennDOT is well into the design phase for a redesign and rebuild of Route 30 to include major utility relocations, drainage, and alignment redesign that will create significant construction related congestion for multiple years so that a multimodal plan for construction, as well as long term operations, can and should be incorporated into the multi-year construction project. This proposed research project will: 1) Develop a generic regional network model to estimate/predict time-varying traffic evolution on all roads in the Allegheny County and Westmoreland County, with the focus on the proximity of North Huntingdon Township. The model estimates origin-destination traffic demands within the region and captures travel behavior of those travelers (in particular their time-varying route choices, and modal choices); 2) Conduct a case study for Route 30 road closures: assess the dynamic traffic impact of road construction projects on Route 30 in the region; propose travel demand management (TDM) to mitigate overall impact caused by closures. The TDM plans include traffic detour plans (provided to residents via online webpages or emails), traffic signal timing on major intersections and on-site detour strategies through Dynamic Message Signs (DMS), and multi-modal transportation solutions.
