  1. Trip Generation: Police Stations By: Armans, Peter Edmonds, Susan M. Gillenwater, Jennifer M. Marticorena, Norberth R. Monsef, Kouros Zaher, Ali B. Zaher, Mouhamad B.

  2. Purpose of Trip Generations • The first step of traffic forecasting • It predicts the number of trips originating from or destined for a location • Trip generation is used by planners to determine fees and taxes for new construction

  3. Police stations Not stand-alone police station

  4. Differences Between Stand Alone Stations and Community Centers ○ Stand Alone Stations Are for Police Purposes Only ○ Community Centers Include Uses for Community Meetings, Courts, Fire Stations, or City Offices

  5. The Troutdale Police Station A Stand Alone Station Police Vehicle Parking

  6. Portland City Police (106th Station)

  7. Portland Police Bureau – Traffic division

  8. Purpose of Our Project • ITE Manual (Institute of Transportation Engineering) • The trip generation as described in the manual is based on land use and building square footage • The manual, however does not include information regarding stand-alone police stations • Our purpose was to gather statistical data to create a trip generations for stand-alone police stations

  9. Process Important Factors • Traffic Caused by the Existence of the Station • Building Uses • The Building’s Size • Parking Spaces • Number of Employees • Peak Hours of Operation Data Collection • Between the Hours of 4 PM to 6 PM • Time Intervals of 5 minutes • Note Police Vehicle or Private Vehicle • If Necessary Differentiate Between Police Traffic and Other Traffic

  10. Data Collection

  11. Analysis

  12. Analysis

  13. Land Use Area vs. Trips

  14. wrapping up • The linear regression result Trips = (1.6 x building square footage) + 2.9 • This formula can be used to predict future trip generations • It would be desirable to conduct more data collection, with duplication of police stations for more accurate trip generation • Examples
