Parking Demand Study

In response to community concerns, the Thruway Authority undertook an extensive study to determine the total number of parking spaces needed to support visitors to the shared use path.

Process Results • Determine average catchment area: 15 miles • Establish percentage of catchment area population Step 1: Collect data from similar bridge and park facilities visiting facility for peak hour (i.e., weekend afternoon): in May and June 2014 (see map below for locations) 0.019%* • Mode of Arrival: -- 59% Auto -- 21% Walk -- 19% Bike -- 1% Transit • Auto Occupancy: 1.85 people per car

*Based on average hourly visitation divided by the average population in each catchment areas. • Apply 15-mile catchment area to New NY Bridge location to establish population pool: Step 2: Calculate New NY Bridge “Catchment Area” -- East side of bridge: 1,571,893 (area that visiting population would originate from) -- West side of bridge; 866,128 -- Total: 2,438,021

• Apply 0.019% peak hour visiting population to Step 3: Estimate number of visitors in the peak hour 2,438,021 population: 473 visitors (hourly visitation) to the New NY Bridge • Auto (59%): 279 visitors • Walk (21%): 99 visitors • Bike (19%): 90 visitors Step 4: Determine number of visitors that would arrive via auto, • Transit (1%): 5 visitors bike, or walking from data collected at other sites (modal splits) • TOTAL: 473 visitors

• Apply 1.85 person/auto occupancy to the 279 visitors arriving by auto Step 5: Establish number of parking spaces needed • Split spaces based on east side and west side catchment area population (from Step 2)

Key Findings: 151 total parking spaces are needed for both counties; 97 spaces in Westchester and 54 spaces in Rockland.
