I I I I I I I I I I I I I I I I I I I Traffic at the entrances also operates very smoothly. Whi Ie through traffic volumes on Si Iver lake Road are relatively high, there are two lanes provided in each direction. If a vehicle is waiting to make a turn into the center, through traffic can pass in the other lane. TRIP GENERATION The amount of traffic generated by a development depends on the type and size of the development. Two source? of trip generation information were used in this analysis, and the results were very simi lar. Table 1 shows the comparison of estimated trip generation using an Institute of Transportation Engineers' report and actual entrance counts made by BRW. The fact that there is so little difference between the estimated trip generation and the entrance counts indicates that businesses in the center are generating trips at an average rate, and that these average rates can be appl ied to the expansion of the center. Table 2 illustrates the calcu- lation of trip generation by existing and proposed development. For pur- poses of this analysis, trip generation by the restaurant which has been proposed at this site has been included in order to present a "worst case" condition. POST-DEVELOPMENT TRAFFIC VOLUMES The trips expected to be generated by the combination of the existing and proposed development were assigned to the entrances to the shopping center and to the streets near the center. Figure 2 shows PM peak hour traffic volumes expected to occur after the proposed development is fully operational. These volumes are used to analyze post-development traffic flow conditions. CAPACITY ANALYSIS The traffic expected to occur at and near Rice Creek Plaza after the pro- posed development is implemented wi I I be served at a very high level of service by the existing roadways, shopping center entrances and traffic control devices. No improvements or changes of any type are required to serve tr ips generated by the expanded shopp i ng center. Capacity analyses of the intersections of Silver Lake Road with Mississippi Street and with Rice Lake Road using post-development PM peak hour volumes indicate that traffic at these intersections wi I I continue to experience Level of Service "A" operating conditions (essentially no delay or congestion). The residential development now under construction west of the site generates very low levels of peak hour traffic (see Figure 2) and wi II have no noticeable impact on traffic flows near the shopping center. Entrances to Rice Creek Plaza are wel I positioned and designed to serve the traffic expected to use them. The four-lane wide roadways now provided along Si Iver lake Road and Mississippi Street ,provide more than adequate capacity to serve the combination of through traffic and traffic turning into and out of the shopping center. 4
