A traffic impact analysis shall be required for each development when the following traffic peak hour trips are exceeded. 1. If the Institute of Transportation Engineers Trip Generation Manual indicates that the proposed development shall generate an equal or a less amount of traffic than the existing development, then no traffic impact analysis shall be required. 2. If the Institute of Transportation Engineers Trip Generation Manual indicates that the proposed development shall generate more traffic than 50 peak hour trips, then the following shall apply: A. Limited traffic impact analysis. If the proposed development shall generate greater than 50 and less than 150 peak hour trips, either in AM or PM, the developer shall submit a limited traffic impact analysis which shall include the following: (1) The proposed trip generation and distribution. (2) The source of the information submitted, for example the Institute of Transportation Engineers Trip Generation Manual. If a source other than the Institute of Transportation Engineers Trip Generation Manual is used, then a comparison between the source used and the Institute of Transportation Engineers Trip Generation Manual shall be submitted. (3) An analysis of the ingress and egress of the development in relation to the level of service on the adjacent roadway system. (4) The study shall include recommendations for any roadway or intersection improvements to maintain the existing level of service. (5) An analysis of the roadway capacity, whether existing or proposed, on all roadway links abutting the proposed development site and identification of roadway and/or intersection improvements necessary in order to maintain the existing level of service. (6) An analysis of the capacity and of the level of service of the nearest signalized intersection in each direction from the major entrances into the development. B. Comprehensive traffic impact analysis. If the proposed development shall generate greater than one hundred fifty (150) peak hour trips, either AM or PM, the developer shall submit a Comprehensive Traffic Impact Analysis which shall include the following: (1) All requirements of A (1), (2), (3), (4), (5), and (6) above. (2) Graphs, maps and charts showing how the traffic shall be distributed onto the existing transportation network within a minimum of one-half mile of the proposed development, and an analysis of the capacity and of the level of service of each roadway link and intersection within this area for both existing and proposed conditions. (3) Recommendations as to how any deficiencies determined by the analysis shall be resolved, including signalization and roadway geometrics. |
