Parking Availability, On-Street Parking Behaviour, and Residential Road Capacity: Evidence from a Household Survey and Correlation Analysis

Abstract

In residential neighbourhoods, the provision of parking often fails to keep pace with increasing levels of private vehicle ownership.As a result, on-street parking becomes common practice, gradually affecting the functioning of local roads.This study looks at how parking availability and on-street parking behaviour are related to changes in residential road capacity.The analysis is based on a household survey of 215 residents, combined with direct observations of parking conditions and street layouts.Correlation analysis was applied to examine the links between parking supply, vehicle ownership, and actual parking practices.The findings indicate that limited parking provision is closely associated with a higher dependence on on-street parking, especially in areas characterised by smaller housing units with restricted garage space.In many cases, vehicles are parked for extended periods, and parking configurations such as perpendicular or irregular arrangements further reduce the usable width of the carriageway.This, in turn, makes vehicle manoeuvring more difficult and increases the likelihood of localised congestion and access-related conflicts.Differences in parking behaviour are also observed across households, with income level, housing type, and vehicle ownership shaping both parking demand and parking location choices.Taken together, the results suggest that parking conditions in residential areas should be understood as part of everyday transport performance rather than treated solely as a matter of spatial provision.Measures aimed at improving parking supply, managing on-street parking practices, and aligning residential design with actual patterns of vehicle ownership may help to ease pressure on local roads and improve overall traffic conditions at the neighbourhood scale.
