<br />LINSCOTT, LAW & GREENSPAN, engineers LLG Ref. 2-17-3881-1 <br />Tustin Avenue Retail, Santa Ana <br />N:\3800\2173881 - Tustin Avenue Retail, Santa Ana\Report\3881 - Tustin Avenue Retail, Santa Ana TIA 03-13-18.doc <br /> 14 <br />5.0 PROJECT TRAFFIC CHARACTERISTICS <br />5.1 Project Traffic Generation <br />Traffic generation is expressed in vehicle trip ends, defined as one-way vehicular movements, either <br />entering or exiting the generating land use. Generation equations and/or rates used in the traffic <br />forecasting procedure are found in the 9th Edition of Trip Generation, published by the Institute of <br />Transportation Engineers (ITE) [Washington D.C., 2012]. <br />Table 5-1 summarizes the trip generation rates used in forecasting the vehicular trips generated by <br />the proposed Project and also presents the project’s forecast peak hour and daily traffic volumes. As <br />shown in the upper portion of Table 5-1, ITE Land Use 931: Quality Restaurant and ITE Land Use <br />946: Gasoline/Service Station With Convenience Market and Car Wash trip rates will be used to <br />forecast the trip generation of the existing development. ITE Land Use 820: Shopping Center, ITE <br />Land Use 937: Coffee/Donut Shop With Drive-Through Window, and ITE Land Use 945: <br />Gasoline/Service Station With Convenience Market will be used to forecast the trip generation of the <br />proposed Project. <br />A review of the middle portion of this table indicates that the existing land uses generate 1,257 daily <br />trips, with 39 trips (21 inbound, 18 outbound) produced in the AM peak hour and 66 trips (37 <br />inbound, 29 outbound) produced in the PM peak hour. <br />A review of the lower portion of Table 5-1 indicates that the proposed Project is forecast to generate <br />2,135 daily trips, with 120 trips (63 inbound, 57 outbound) produced in the AM peak hour and 118 <br />trips (58 inbound, 60 outbound) produced in the PM peak hour. <br />Review of the last row of Table 5-1 shows that with application of existing trip credits, the proposed <br />Project is forecast to generate a new of 878 daily trips, a net of 81 (42 inbound, 39 outbound) AM <br />peak hour trips, and a net of 52 (21 inbound, 31 outbound) PM peak hour trips. <br />5.2 Project Trip Distribution and Assignment <br />Figures 5-1 and 5-2 present the trip distribution pattern for the gas station and commercial <br />components proposed Project, respectively. Project traffic volumes both entering and exiting the <br />project site have been distributed and assigned to the adjacent street system based on the following <br />considerations: <br /> location of site access points in relation to the surrounding street system, <br /> the site's proximity to major traffic carriers and regional access routes, <br /> physical characteristics of the circulation system such as lane channelization and presence of <br />traffic signals that affect travel patterns, <br /> presence of traffic congestion in the surrounding vicinity, and <br /> ingress/egress availability at the project site. <br /> <br />The anticipated near-term AM and PM peak hour project traffic volumes associated with the <br />proposed Project (the net trip volumes and existing trip credits) are presented in Figures 5-3 and 5-4, <br />2-79
