Abstract
Car parking is a challenging part of urban transportation and traffic violations cause many problems for citizens. Studies have shown that there is a direct relationship between vehicle parking violations and urban places. In this study, we investigated the spatial distribution of vehicle violations in a region of Tehran, Iran, that is suffering from a heavy traffic load and heavily polluted air. Although there are two dissimilar urban segregations in the north and south of the study area, in both of the regions, about 70% of all curb-parks are legal, while the remaining are illegal. However, our analysis indicates a dissimilar pattern of car parking violations. Additionally, spatial analysis reveals a direct relationship between some POIs (Point of interests) and the occurrence of car park violations. For example, the number of vehicle park violations around the hospitals is more than the average of the study area. However, the number of park violations around the universities is less than the average. Our results also show that POIs have an impact radius that leads to violations occurring in that area. For example, the influence range of a hospital on the creation of car park violations was estimated at 125 meters. Our presented approach along with the discussed findings and conclusions can be useful to an extensive range of stakeholders, including urban planners, traffic police departments, local municipalities, law enforcement agencies and environmentalists, to have a better perspective of infrastructure planning.
Highlights
Since the advent of motor vehicles, providing places for parking in cities has been an important issue that should be considered in urban planning and management
The traditional taxi-taking attitude in the relatively modernized Iranian traffic infrastructure does not conform with the current driving behaviours suitable for modern societies
The number of curb-park violations was estimated by using some parameters such as type and number of commercial POIs
Summary
Since the advent of motor vehicles, providing places for parking in cities has been an important issue that should be considered in urban planning and management. In a field study in a small area of Los Angeles by Shoup [9], the average distance travelled to find an appropriate parking space by cars on the streets was estimated to be 3600 miles per day Drivers significantly reduce their speed and increase their heart rate when searching for street parking [10]. In an analytical and quantitative study, Guo, Gao [2] using street-width variables and the number of moves required to perform a park, showed that stops along the streets had a significant effect on slower traffic and increased the city trip time of other drivers. These violations follow certain patterns, and understanding these patterns can be used to make more efficient decisions to tackle the problem of curb-parks in cities.
