FEE-19-195O 13:49 FROM WESTWOOD PROF. SERVICES TO 8885979 P.03 3) Existing Traffic Operations - While counting vehicles at Long Lake, Bronson and the existing gas station observations were made of the existing traffic operations in the area. Over the four peak period hours observed, vehicles experienced no difficulty entering Long Lake Road from either Bronson Drive or the existing gas station. As shown in the count data the volumes turning onto Long Lake Road are quite low. It was observed that seven times between 4:00 p.m. and 6:00 p.m. on Friday, February 16, 1990, southbound queues extended far enough back from the signal at TH 10 to block the gas station exit and the Bronson Drive access onto Long Lake Road. It is noted that these queues only reached these lengths at the end of the red light time interval for Long Lake as vehicles randomly arrived and filled in the queue. In every instance when the signal turned green for Long Lake these queues fully cleared and access to Long Lake was free again. (In the morning peak period, 7 a.m. - 9 a.m., Thursday, February 15, 1990, only one such queue was observed) . 4) Accident Data: The Minnesota Department of Transportation maintains a computerized data record of accidents on roadways throughout Minnesota. A request was made to the East Metro MnDOT office for accident records at Long Lake Road and Bronson Drive. For the years 1986 - 1989 MnDOT records show no accidents at this location. MnDOT personnel did caution that the accuracy of their data was best on State Highways and that City • officials may have data for local roadways that MnDOT has not received for its records. (NOTE: Ramsey County does not maintain separate accident records. A request for accident data from Ramsey County resulted in a referral to MnDOT) . Future Conditions 1 ) Lavout: The proposed gas station renovation will result in a layout which cleans up the existing site and provides for a driveway access onto Long Lake Road. Presently there is no curb along either the west (Long Lake) side or north (Bronson) side of the gas station property. Vehicles enter the station at an implied driveway off of Long Lake (Implied by sign locations and by where vehicles are parked) . On the north side of the property the bituminous surface of the station site runs into the bituminous surface of Bronson Drive. The proposed layout will provide a 30-foot driveway onto Long Lake separated some 20 feet from Bronson Drive. 2) Trip Generation: Based on records at other Phillips 66 stations of the type proposed, it is estimated that approximately 400 vehicles will be served by the station on a typical weekday. Phillips 66 had no hourly breakdown of this daily volume. The Institute of Transportation Engineers (ITE) report "Trip Generation" has a limited amount of information on hourly trip patterns at gas stations. The ITE data suggests that p.m. peak hour trip volumes may be as high as 8% of the daily station volume (based on stations surveyed by ITE) . Using this S information, and estimating high, we may say that 10% of the daily station volume could occur in the p.m. peak hour which is the critical hour for analysis. (10 percent of 400 daily customers is 40 in the p.m. peak hour) . It is also noted that in the p.m. peak hour observed at the existing station one third of the traffic exiting onto Long Lake made a left turn, two-thirds made a right turn.
