PARKING DEMAND BY TAZ URBAN GIS and AERIAL PHOTOS

BASIC ESTIMATES OF PARKING DEMAND AND SUPPLY: GIS + Aerial photos + Population Census

Estimation of demand: Night: Householders*car ownership rate Day: Office area/20 or proportional to Shops’ turnover Estimation of supply: Curb: Length of streets /5 m – prohibited places Lots: Lots area /8 sq m * number of floors

DESTINATION-PARKING PLACE DISTANCE: Field surveys + Population Census

Given the parking fees, driver’s satisfaction is defined by • Duration of the parking search • Distance between the parking place and destination

Parking spatial pattern

The distance between the parking place and the destination

Estimated based on the data of owners’ addresses

Obtained with the PARKAGENT model

Standard GIS and census data together with the proper survey methodologies guarantee reliable estimates of parking demand, supply, and spatial patterns

For typical Western city,

field surveys demand 20-40 person-weeks

and are performed in 2-4 weeks

Drivers’ parking

behavior

Analysis of drivers’ parking trajectories, as registered by the GPS,

provides adequate heuristic algorithms of drivers’ parking behavior

Parking behavior does not depend on gender and age. The only meaningful feature is driver’s experience of

parking in the area, and its effects are currently studied

Parking dynamics in space and time

Simulation models adequately describe parking dynamics in space and in time.

The models exploit data on parking demand, supply, turnover and on the

drivers’ parking behavior, and are easily adjusted to a new city

The models reveal several universal characteristics of the urban parking patterns. Model results fit very well to the survey data
