Mr. Mike Westland December 18, 2003 Page 2 were made primarily from the easterly driveway where 70 turns were observed in the 2-hour period. Only seven were made from the west driveway. Southbound traffic entering the station generally uses the north entrance, while northbound traffic uses the south entrance from Lexington A venue. These volumes and pattel11s are consistent with the observations made during several visits to the convenience store complex. Total trips in the two hours monitored showed a volume of 575 vehicle trips, counting both inbound and outbound vehicles. The Institute of Transportation Engineers Trip Generation Handbook indicates the p.m. peak hour (I-hour) volume at a station similar to the SuperAmerica would be 281. This is consistent with the counts made at the driveways. Using the same reference book, it is anticipated there would be approximately 3,400 vehicle trips per day. Based on counts and observations at other SuperAmerica stores, this is among the higher generating stores. Current Station Operation The station store currently has its pump islands aligned so that the vehicles are facing southwest or northeast in front of the station store. Parking for the convenience store is located in the northwest area of the development or along the east side. There are a few additional stalls near the store front that faces southwest. Vehicles traveling to the gas pumps may enter from any of the four driveways depending upon traffic on Lexington Avenue or County Road B. Traffic entering from the south or west driveways has little conflicts in reaching the pump islands. Based on observations and driveway counts, most patrons of the gas pumps have a route through the station. As an example, the route might include a northbound right tUl11 into the south driveway, park at the pumps, and exit by traveling north through the station and making a right turn back onto Lexington A venue from the north driveway. Patrons may either use the gas pumps or the parking areas for their time in the store. Observations at this station and others show that some patrons park only at the pumps and either pay at the pump or leave their vehicle and pay at the inside cashier. Others use the gas pumps and make a multi- purpose trip by picking up items within the store and paying the cashier. There are also a significant number of customers who use the parking spaces and only the convenience portion of the store, not using any services at the gas pumps. Observations and estimates at other stores show the split between gasoline patrons and convenience store-only patrons at approximately 50 percent each. Congestion occurs in this station with deliveries by various vehicles. There is a entry to the storage area of the store at the northwest COl11er along with an area for delivery trucks. Observations show trucks parking along the south and comer islands and wheeling merchandise into the store. While these trucks are generally parked away from the heavy driveway movements, they do cause some interference when entering or exiting their parking area and in constricting some of the movements around the gas pumps. Trash pickup is at the northeast comer of the facility where a covered trash receptacle exists. Trash trucks must drive in and back out and frequently similar station stores have trash pickup in the non-peak hours. The underground storage tanks are located near the east driveway. While the tanks are being filled, the trucks apparently partially block circulation around the south and east sides the building. Only
