- - -, ......,. "-' ',~ r. I,)':" Mr. John Weicht -3- May II, 1994 e In order to analyze tlle traffic implications of the proposed auto mall, an understanding of existing turn movement volumes at the Main St./Carson 51. intersection was needed. To facilitate this understanding, turn movement counts were performed during the p.m. peak time period (4-6 p.m.) in fifteen minute intervals on May 4, 1994, by Benshoo( & Associates, Inc. Existing total approach volumes were also obtained frail) Maier Stewart & Associates, Inc. for the T.R. 169/Main SI. intersection. Accident History at Main St./Carson St. Intersection A listing of accidents which have occurred at the Main St./Carson SI. intersection Was obtained from the Elk River Police Department. Thi. listing showed that OVer the past four and one half years, 15 accidents had been reported at this intersection, for an . average of three and one third accidents per year. It was further learned from the Chief of Police that one type of accident bad OCcurred more frequently tban others at the intersection. This type of accident involVed eastbound vehicles On Main SI. that were turning left onto northbound Carson SI. hitting vehicles on Carson St. waiting to turn onto Main St. Roadway Altemativ~ Two different roadway alternatives were considered in the traffic analysis. The first involVed having the only access to Carson St. at Main St., as is currently the case. The other alternative involved the creation of a right tum in/out access on T.R. 169 at the north end of C?I"son Se I in addition to the Main St. access. . TRAFFIC FORECASTS Trip Gener~tion Trip generation rates were established for the ,Proposed development to acconnt for the expected new and pass by trips. Trip generation rates for the auto related uses were based on studies done at simIlar locations by Benshoof & Associates, Inc., while the trip generation rates for the other retail uses were based On information obtained from representatives of those uses. We are confident that the trip generation rates for the Mr. Movies and the Little Caesar's Pizza uses are conservatively high. Next, it is important to classify trips to and from the development in terms of the fOllOWing two categories: . · New trips - These are trip. that either would be new trips solely to and from the development. · . Passby trips - These are existing · through' trips on T. R. 169 that in lhe fu ture would include a stop at the proposed development. Based on Our experiences and information published by the Institute of Transportation Engineers, we would estimate that approXimately 90 percent of the trips generated by the development would be new, while 10 percent would be classified as passby. To aCCOunt for multipurpose trips, or trips that would make stops at more than one of the businesses in the development, a five percent reduction factor was applied to the overall trip generation.
