Page 2 TRIP GENERATION The Institute of Transportation Engineers (ITE) Trip Generation Manual, 11th Edition, was used to calculate the estimated traffic generated from the existing Bingo Hall and the estimated additional traffic generated by the proposed Event Center. It should be noted that the data provided by ITE only provides one data source and should be used cautiously due to the limited sample size. However, Table 1 does show the estimated trips entering and exiting the existing site during the weekday AM and weekday PM peak hours if the building was at approximately half of its capacity (250 people) Table 1: Existing Trip Generation Summary Bingo Hall 250 People' 35 3 38 1 10 1 110 120 Notes: 'Assuming half of the Bingo Hall's capacity for comparison purposes. 20nly one data set provided by ITE for a Bingo Hall, no daily trip generation estimates are With the existing land use on site, a total of approximately 38 trips enter and exit during the AM peak hour and 120 trips enter and exit during the PM peak hour. A trip generation review was completed for the proposed event center development. However, the ITE Trip Generation Manual does not provide trip generation data for venues comparable to the proposed site. Instead, new trips were estimated based on information provided in the site plan (Attachment A) and the following assumptions for a large, maximum capacity event: • The site plan estimates that the venue has a 515-person capacity and will include a surface parking lot of 145 parking stalls (including 5 ADA-accessible stalls). It is assumed that all event parking will be on -site and no parking will occur outside of the designated surface lot. Trip generation analysis uses the parking capacity to estimate the new trips. • Trips will enter and exit at the current driveway. • 10% of people will arrive prior to main peak hour for other attendees (staff, vendors, etc.). It is assumed that there will be one vehicle per attendees that arrives early (15 vehicles). • 90% of vehicles will arrive during the same one -hour period. It is assumed that attendees will carpool to the event, with approximately 3 people per vehicle (130 vehicles). • Larger events are expected to last longer than one hour, so it is assumed that new trips will be entering and exiting during different hours. • The venue includes a reception area, which indicates that the exiting traffic will be dispersed over 1-2 hours. Therefore, a lower rate for exiting vehicles is applied. Based on these assumptions/factors, the following rates are approximated based on the venue's capacity': o Entering: 0.25 with 100% entering (130 trips) o Exiting: 0.12 (0.25 x 40%) (62 trips) Based on these assumptions and using the maximum on -site parking capacity of 145 spaces, the venue could generate approximately 130 entering trips in a one -hour period prior to the event and 62 exiting trips after the event. It is expected that the peak activity will occur on a weekend evening, during off-peak hours from adjacent street networks and surrounding businesses. Compared to the existing Bingo Hall use, there is an additional 120 trips entering in one hour and fewer trips (48) expected in the exit during one hour. ' Spack, M. (2018, February 13).
