Component

A rapidly developing area of the City was beginning to experience land development pressure that has the ability to lead to a level of trip generation that would render the transportation network non-functional. The District Department of Transportation (DDOT) composed a methodology to evaluate potential impacts from future land development projects based on the trip generation and modal split assumptions found in a robust evaluation of the transportation network in that area of the City. The methodology focused on capping trip generation rates for a land development project to be consistent with rates assumed in previously completed study efforts that involved the region’s travel demand model and microsimulation. The approach ties conditions expected in some future build-out scenario to the projected trip generation and/or the amount of on-site parking spaces needed by a new development project. Through this method, the amount of parking spaces and/or the vehicular trip generation estimates become a function of the planned travel conditions and can be capped to facilitate efficient traffic operations.
