17-02 — Successful Approaches to Accommodate Additional Modes and Services in Existing Right Of Way

State DOTs are increasingly being challenged to accommodate a variety of modes and services within existing right of way. DOTs may be asked to dedicate (in whole or part) existing lanes or right of way to transit, high occupancy vehicles, bikes, freight or enhanced pedestrian access. The decisions to accommodate the additional modes and services requires a variety of site and community specific trade-offs, design and construction considerations and operational needs that have to be addressed for such accommodation to be accomplished successfully.

This scan will evaluate the design, operational and policy/procedural decisions that State DOTs have been faced with in response to a proposal from an external agency or entity to accommodate additional modes and services within existing ROW. A particular interest is on the dedication of existing lanes to transit as part of a Federal Transit Administration (FTA), Capital Investment Grant (CIG) project especially in urban settings. The scan team will examine technical issues associated with design, construction and operations/maintenance, but will also be strongly focuses on organizational, policy, procedural and “relationship” issues.

Scan Results and Report

Ready Results Brief

 

Implementation and Impact

Scan team member Dennis Slimmer, formerly with Kansas DOT, presented scan findings and recommendations to the TRB ACP35 Standing Committee on Managed Lanes at their annual (virtual) meeting as part of the 2021 TRB Conference. Also at the TRB Conference, Dylan Counts shared highlights and recommendations of the scan study with the TRB AP075 Standing Committee on Light Rail Transit Systems.

Scan team members (including Scan Chair Beth Bonini of Pennsylvania DOT and Scott Pedersen of Minnesota DOT ) and scan participants, conducted the first in a series of two AASHTO hosted webinars which presented highlights, findings and insights on the following transit projects: Detroit’s Qline Streetcar, Richmond’s Pulse BRT, and Minneapolis’ I-35W Orange Line BRT.
