(a) The impact of the proposed project on intersections and roadways within the study area shall be analyzed by distributing the traffic and assigning it to the roadway. The directions from which traffic will approach and depart the site can vary depending on several factors, including the type and size of the proposed development, the surrounding and/or competing land uses, and the conditions on the surrounding street system. Trip assignments shall be made considering logical routings, available roadway capacities, left turns at critical intersections, and projected and perceived minimum travel times.
(b) An influence area shall be designed to assist in the distribution of traffic. The influence area shall include surrounding communities and roadways from which traffic is expected to be attracted. This is normally determined by a marketing study. If no study exists, the influence area shall be determined based on reasonable estimates. Existing trip distribution data from similar, developed sites within the immediate vicinity may be used for making assignments.
(c) Many land uses such as fast food restaurants, service stations, restaurants and shopping centers not only generate new trips, but also attract trips that were already passing by in the traffic stream. The procedure described in the Institute of Transportation Engineers’ Trip Generation shall be used to account for these “pass-by” trips.
