Corridor Studies & Multimodal Design

Project Details

Roadway corridors in our communities are strained under increasing pressure to accommodate the evolving demands of land use. While the land they serve has changed with residential and commercial growth, the roads and streets themselves have often remained relatively unchanged. Retrofitting these corridors to improve multimodal needs becomes challenging with competing interests (utilities, right-of-way, etc). TPD takes a comprehensive approach to addressing such corridor challenges and to identifying multimodal upgrades. By combining local insight, an understanding of development trends, expertise in multimodal design, and a keen eye for opportunities, we develop solutions that cater to diverse needs. Our approach integrates land use and transportation considerations into the decision-making process to arrive at reimagined corridors that serve everyone. Our corridor studies work ranges from conceptualization to final design and elevate safety for people of all ages and abilities.


1st Street East and West Shared Use Path Planning and Design (C-5624)
Conover, NC

TPD collaborated with the City of Conover to develop design plans focused on alleviating congestion along a key 2.1-mile downtown corridor and connecting existing recreational trail facilities. The design consisted of a lane-reduction strategy that incorporated pedestrian and bicycle improvements, improving traffic flow for vehicles while creating a safe space to walk and bike. New dedicated turn lanes, midblock crossings, and a shared use path were included in the final design. The project area included 1st Street East and West from just south of I-40 to the Thornburg Drive (NC 16) intersection. Key elements of this project included conducting traffic studies, engaging the community through various channels (such as a dedicated website), preliminary engineering (up to 30% design), a preliminary NEPA environmental review, bicycle and trail facility design, pedestrian crossing study and design, and incorporating Americans with Disabilities Act (ADA) enhancements.

Broad Street Active Transportation Plan
City of Bethlehem, Lehigh and Northampton Counties, PA

Broad Street plays a pivotal role as a major multimodal transportation corridor through the City of Bethlehem, serving as a primary route to downtown for people walking, biking, driving, or riding the bus. In collaboration with the City of Bethlehem, TPD facilitated this project funded by the Pennsylvania Department of Health WalkWorks program, to develop an Active Transportation Plan specifically for Broad Street. The goal of the project was to improve safety for people walking and biking by identifying short term priorities and a presenting a phased implementation plan.

Patton Avenue Corridor Study
City of Asheville, Buncombe County, NC

TPD is collaborating with McAdams as a subconsultant on a comprehensive corridor study for Patton Avenue in the heart of Asheville’s downtown. The purpose of this study is to develop transportation, land use, and urban design recommendations for Patton Avenue from the Jeff Bowen Bridge to Pack Square. As one of the main thoroughfares leading into downtown, Patton Avenue’s aesthetic appeal and infrastructure quality greatly influence perceptions of Asheville as a destination. Enhancing the visual appeal and functionality of this key roadway can contribute to creating a positive experience for those arriving in the city, both visitors and commuters alike.The project will position Patton Avenue to develop as a thriving mixed-use corridor and establish it as a complete street and prominent gateway to downtown. TPD’s responsibilities include public and stakeholder engagement; multimodal planning design; traffic analysis; alternatives development; and road diet and roundabout feasibility analysis.

US 17 & 17N Road Safety Audit
Cities of North Myrtle Beach & Myrtle Beach, Horry County, SC

As a sub consultant to AECOM, TPD contributed expertise in bicycle and pedestrian safety guidance for two SCDOT roadway safety audits in North Myrtle Beach, SC. TPD actively participated in several stakeholder meetings, conducted two field visits / safety assessments, provided bicycle and pedestrian safety recommendations, and assisted with overall corridor recommendations development. This assessment included a review of crash data, traffic operations, field observations and site conditions. Recommended safety countermeasures included pedestrian crossing enhancements such as lighting, refuge islands, enhanced signing and marking, adjustments to signal phasing, ensuring compliance with ADA requirements, and reducing crossing distances for pedestrians. Additionally, TPD conducted evaluations of bicycle safety and crossings and assisted with the development of several access management scenarios to optimize traffic flow and improve safety along the corridor.
