DCCM developed the LRTP for the Shreveport-Bossier City metropolitan area. The LRTP addressed regional and local transportation goals and objectives and encompassed all modes of transportation.

The project included extensive public outreach and stakeholder consultation, including public visioning meetings; detailed socioeconomic projections based on a local, expertdriven Delphi Process; and a complete remake of the regional travel demand model (TDM), including a mode-choice component. The plan also addressed Transportation System Management and Operation (TSMO) strategies, multi-modal system deficiencies, safety concerns, and project travel demand for the horizon-year 2040. In addition to the traditional bike and pedestrian element, the project developed a Caddo Parish-specific bike plan that addressed unique needs within the community. DCCM conducted a series of scenario-based planning exercises to inform the plan development.

DCCM also developed performance-based metrics used in a Project Selection Process (PSP) that addressed deficiencies identified in the MPOs triennial audit by FHWA. The PSP provided a link between the public visioning process, stakeholder input, and prioritization by the Technical Committee that addressed the multi-modal needs through the 2040 planning horizon.

A new regional TDM was constructed based on the state of Arkansas’s statewide model interface and available local data. The new TDM was a state-of-the-practice four-step model that included a cross-classification trip generation model, a gravity model for trip distribution, a mode choice model to split person trips by mode, and traffic assignment by time of day. The TDM included a feedback loop, intersection delay, and advanced reporting features.
