each sub-section at an intersection, landmark orshop.Step 2: conducting the on-site surveysSurveyors walk the same route every hour and foreach sub-section document the license plates ofall vehicles (last four digits). The location of everyparked vehicle is documented, distinguishingbetween parking on-street (between the curbs),on the sidewalk and on the setback. Surveys startat 7.00am and start the last round at 9.00pm,finishing around 10pm.Simultaneously, existing on-street and setbackparking supply for each section is documented.Step 3: survey data analysisFrom the parking demand and supply the occupancyis retrieved for every hour and every streetsection.From the license plate documentation theparking duration of each car is documented andbundled per street section. The turnover per parkingspace is obtained by comparing the parkingduration and parking supply. The parking locationis documented and presented per street section.OutputThe surveys provide insights into the parkingbehavior on every street section. The averageparking time is found, giving insights into theeffectiveness of the parking price. For instance,the severance of illegal parking (on sidewalks andmost setbacks) is found for each street section.Moreover, shortages and surpluses of vacant parkingspaces are mapped and help in reorganizingand balancing parking supply and demand.3.2.2 Off-street parkingGoal of the surveys is to document existing parkingpractices. Studied are:●●parking demand – documentation of thenumber of cars parking throughout the day;●●parking supply - documentation of thenumber of officially marked parking spaces●●parking occupancies, turnovers and durationsare derived from the survey data above.publicly accessible and of reasonable size.Step 2: conducting the surveyFor each off-street parking location, surveyors areassigned to every entrance/exit and document allincoming and outgoing cars. The time (5 minuteintervals) and license plate (last four digits)of every car entering and exiting the off-streetparking lot are documented, including the notewhether the car was entering or exiting. Thelicense plates of cars already in the parking lotsare documented before the survey starts. Parkingsupply is documented as well.Step 3: survey data analysisFrom the parking demand and supply the occupancyof the off-street parking location isretrieved throughout the entire day. Parking durationfor each car is obtained from the license platedocumentation. The turnover per parking space isobtained by comparing the parking duration andparking supply.OutputThe parking duration, occupancy and vacancy isderived from the survey results. Off-street parkingvacancy is important to accommodate excessdemand that currently parks on sidewalks andsetbacks.3.3 Case study resultsThe Guang’anmen area is described first, followedby Guomao (page 78) and Cheniandian andLiufanf areas (page 85).3.3.1 Guang’anmenThree areas in Guang’anmen were studied. TheLangqin area (page 19) is a residential area witha large shopping mall and office tower namedLangqin Guoji. The Yuanwuqu area (page 48) isan office and residential area with ground-floorshops. The Xinhe area (page 71) is a residentialcommunity with ground floor shops and oneoffice tower and tea market.Step 1: preparing locationsTo be of value to other drivers, off-street parkingbuildings selected for the survey need to beBeijing Parking, ITDP-China 171 March 2015
