Annex 5 Analysis of Parking Demand and Supply: Example Drawings Created in the Process

This annex shows an example of parking demand and supply analysis in Tokyo’s CBD. It summarizes key tasks and provides various maps created in the process.

Land use, Major Facilities and Traffic Volume

The land use map shows a heavily commercialized CBD within one kilometer radius of the central station. Initially, major destinations were identified and traffic volumes on major arterials are measured.

Parking Demand Survey

Parking management zones are defined based on traffic flow on arterials and land use characteristics. Extent of illegal parking and the parking demand in the area were then estimated by various parking surveys. The figure below shows the seven designated parking management zones, the extent of on-street illegal parking by street, and the calculated parking demand by zone.
