SEH MEMORANDUM TO: Robert Rimstad - Metro Transit FROM: Michael P. McCurdy, PE DATE: November 1, 2010 RE: Rice Street/CR B Park -and -Ride Traffic Analysis 561-1 No. 112888 SEH has completed traffic analysis for Metro Transit of a proposed 270 space park - and -ride lot in the NE corner of the Rice Street /County Road (CR) B intersection. The proposed park- and -ride lot will have access on CR 8, approximately 600 feet from the CR B /Rice Street intersection. Analysis was performed to evaluate the potential traffic impact the added traffic from the park- and -ride lot will have on the adjacent roadway system. The proposed park -and -ride consists of 270 parking spaces. It was assumed the parking lot will generate 0.60 peak hour trips per parking space with a 90% inbound /I0% outbound directional split during the AM peak hour and 10% inbound /90% outbound directional during the PM peak hour. The park- and -ride lot will generate 162 total trips (146 inbound, 16 outbound) during the AM peak hour and 162 total trips (16 inbound, 146 outbound) during the PM peak hour. The park- and -ride lot will also generate 6 inbound and outbound bus trips during the peak hours. The park- and -ride trips were distributed through the surrounding network using directional distribution information from a Metro Transit "TH -36 at Rice Street Park- and -Ride Traffic Model Inputs" memo dated 07/01/2009. The memo breaks down travel approaches by Minneapolis -bound and St. Paul -bound park - and -ride users. According to Metro Transit, the proposed park- and -ride will not have dedicated express bus service to downtown St. Paul stopping at the park -and -ride, but some riders will park at the park- and -ride and go across the street to catch the route 62 or 262 busses which service downtown St. Paul. Metro Transit assumed that approximately 10 % -15% of the riders will do this, and agreed with SEH's assumption that 20 of the park- and -ride users will take the St. Paul busses. The majority of the park- and -ride users distribute to /from the east via Trunk Highway (TH) 36, and the highest volumes generated by the park- and -ride during the AM peak hour are the westbound TH 36 left turn at Rice Street (84 vehicles), southbound Rice Street through at TH 36 (26 vehicles), southbound Rice Street left turn at CR B (135 vehicles) and eastbound CR B left turn at the park- and -ride access (145 vehicles). The highest volumes for the PM peak hour are the southbound park- and -ride access right turn at CR B (145 vehicles), westbound CR 6 right turn at Rice Street (135 vehicles), and northbound Rice Street right turn at TH 36 (84 vehicles) and through (26 vehicles). Traffic analysis was performed using Sim Traffic computer modeling software. Forecast year 2033 AM and PM Synchro /SirTrafffc traffic models developed for the Rice Street/ TH 36 interchange analysis were used for the park -and -ride analysis. The models were modified to include the proposed park -and- ride and Cub Foods access on CR 8, which includes the addition of an eastbound left turn lane at the intersection. The Cub Foods access will be a right -in, right -out access, and therefore, was not analyzed as part of this study. The intersection was assumed to have minor roadway stop control for the park- and -ride approach and the park- and -ride exit will have a single shared left and right turn lane exiting the lot.
