Duration Analysis The parking duration analysis is presented in terms of observed distribution of "parking events" by length of stay. A parking event is defined as when a vehicle is observed to occupy a single space during one observed time period during data collection. Table 1 presents the length of stay by space type for the study area between 9 AM and 6 PM for the weekday. The average user parking on -street in the periphery stays for about an hour longer than a user parking in the core area. This is likely due to the higher amount of unregulated parking in the periphery area. Only 50 percent of on -street parkers stay for an hour or less, likely indicating that some on -street parkers are nearby residents or commuters who park in free unrestricted parking areas. Slightly more than three quarters of parkers use off-street parking for an hour or less, indicating that many visitors park in the off-street lots for short visits to nearby retail and restaurants.

The consulting team developed a customized shared parking model based on the Urban Land Institute's (ULI) Shared Parking Manual. Overall, at the time of data collection, the existing downtown parking inventory within the study area comprised a total of 3,239 publicly available parking spaces. This includes all types of spaces, including short-term and handicap spaces, but excludes parking spaces assigned exclusively with a particular land use. Table 2 provides existing parking inventory within the study area, as well as parking occupancies during the midday peak (around 12 PM) and evening hour (5 PM) parking periods.
