one year of the study date may be used subject to Planning <br />Department approval. A volume/capacity analysis based upon <br />existing volumes shall be performed during the peak highway hour(s) <br />and the peak development generated hour(s), if appropriate, for all <br />roadways and major intersections expected to be impacted by <br />development traffic. Levels of service shall be determined for each <br />signalized intersection or roadway segment analyzed above. <br />This analysis will determine the adequacy of the existing roadway. <br />system to serve the current traffic demand. Roadways and/or <br />intersections experiencing levels of service E or F shall be noted as <br />congestion locations. <br />D) Transportation Impact of the Development -Estimation of vehicular <br />,trips to result from the proposed development shall be completed for <br />the average weekday, the average daily peak hours of highway travel <br />in the study area, and, if appropriate, peak hour of traffic generation <br />by the development. Vehicular trip generation rates to be used for <br />this calculation shall be obtained from an accepted source such as <br />"Trip Generation" (Institute of Transportation Engineers, Fourth <br />.Edition, 1987 as amended). These development generated traffic <br />movements as estimated, and the reference source(s) and <br />methodology followed shall be documented. These generated <br />volumes shall be distributed to the, study area and assigned to the <br />existing roadways and intersections throughout the study area. <br />Documentation of all assumptions used in the distribution and <br />assignment phase shall be provided. All average daily traffic link <br />volumes within the study area shall be shown graphically. Peak hour <br />turning movement volumes shall be shown for signalized and other <br />major intersections, including all access points to the development. <br />Pedestrian and bicycle volumes at school crossings and as otherwise <br />applicable shall be reported. Any characteristics of the site that will <br />.cause trip generation to vary significantly from average rates <br />available in published sources shall be documented, including such <br />factors as diversion of passer-by traffic, internal capture, staggered <br />work hours, or use of transit. <br />E) Analysis of Transportation Impact -The total traffic demand that will <br />result from construction of the proposed development shall be <br />calculated. -This demand shall consist of the combination of the <br />existing traffic generated by the proposed development, and traffic <br />due to other developments and .other growth in traffic that would be <br />expected to use the roadway at the time the proposed development <br />is completed.. If staging of the proposed development is anticipated, <br />calculations for each stage of completion shall be made. This <br />analysis shall be performed for average weekday traffic, the peak <br />highway hour(s) and if appropriate, peak development generated <br />hour(s) for all roadways and major intersections in the study area.- <br />Volume/capacity calculations shall be completed for all major <br />intersections. It is usually at these locations that capacity is most <br />restricted. <br />-31-f- <br />
