This document provides an overview of parking studies and terms. It defines common parking metrics like parking index, volume, accumulation, load, duration, and turnover. It also describes the four main types of parking studies: inventory surveys, patrol surveys, questionnaires, and cordon counts. Additionally, it outlines different types of parking facilities, including on-street options like parallel, angled, and perpendicular parking as well as off-street options such as surface lots, multi-story structures, roof parks, mechanical parks, and underground lots. The goal is to understand how to plan for and analyze parking needs.

2. Parking studies (objectives)
 Understand parking planning is an
integral part of transportation
planning
 Know the definition of parking terms
 Learn the methodology of parking
studies
 Learn how to find out space
requirements for a parking garage

3. Definitions of parking terms
Parking index Percentage of ratio of no. of parked vehicles to
theoretical no. of bays available.
Parking
volume
The total number of vehicles that park in a study
area during specific length of time (usually a
day)
Parking
accumulation
The number of parked vehicles in a study are at
any specified time.
Parking load The area under the accumulation curve between
two specific times. (space-hours)
Parking
duration
The length of time a vehicle is parked at a
parking bay.
Parking
turnover
The rate of use of a parking space. Divide the
parking volume for a specified period by the
number of parking spaces.
