Motor Vehicle Parking Space Dimensions

[DiArya]

According to the "Urban Road On-Street Parking Space Setting Standards," the standard dimensions of general parking spaces are determined based on vehicle size. Small parking spaces typically measure 2.5~2.7 meters in width and 5~6 meters in length. The width of a single-lane turning lane should not be less than 3.5 meters, while a double-lane turning lane should be at least 5 meters wide. The turning area should accommodate a vehicle's one-time turning needs, and for safety or to accommodate medium and large vehicles, it is often set to 6 meters or more. Details are as follows: (Length ≤ 6m, width ≤ 1.8m) vehicles: The standard spacing between vehicles should be no less than 0.5 meters, and the spacing between vehicles and walls or the ends of parking spaces should also be no less than 0.5 meters. (6m < length ≤ 8m, 1.8m < width ≤ 2.2m) vehicles: The spacing between vehicles should be no less than 0.7 meters. Small vehicle parking space: Length ≥ 5 meters, width 2.2-2.5 meters. Large vehicle parking space: Length 7-10 meters, width 4 meters, depending on the specific vehicle model. According to the "Architectural Design Standards for Parking Garages," the dimensions for small car indoor parking spaces are as follows: The external design dimensions of small cars are 4.8m (length) x 1.8m (width) x 2.0m (height). For perpendicular parking, the minimum parking space size should be 5.3m (length) x 2.4m (width), with a minimum driveway width of 5.5m at the front. The minimum distance between small cars and side walls should be 0.6m, and the distance to front and rear walls should be 0.5m. Modern underground parking garages have large floor areas and numerous parking spaces. To ensure free vehicle movement, driveways are planned to be relatively wide. Driveways, as horizontal passages dedicated to parking spaces, account for the majority of the allocated floor area, often occupying 50% or more of the total parking space floor area. Parking space arrangements can be divided into three types: parallel, angled (30°, 45°, 60°), and perpendicular. Large vehicle parking spaces should not use angled or perpendicular arrangements. Details are as follows: Parallel parking space: Standard length of 6 meters, width of 2.5 meters. Angled parking space: Slanted length of 6 meters, width of 2.8 meters, with a vertical distance of 2.5 meters between the two slanted lines. Perpendicular parking space: Length ≥ 5 meters (typically 6 meters), width of 2.5 meters. The optimal standard size is 2.5m x 5.3m. The "Road Traffic Safety Law" stipulates that on-street parking spaces cannot be set on roads with a width of less than 6 meters. Pedestrian crossings, expressways, and main roads are also prohibited from having parking spaces. Within urban road areas, government authorities may designate parking spaces if they do not obstruct pedestrian or vehicle traffic. On-street parking spaces should not interfere with non-motorized vehicle traffic or encroach on their space. They should not be set near intersections, building entrances, or bus stops. Parking regulations, including vehicle types and time limits, should be clearly indicated with signs. Measures should be taken to avoid obstructing vehicle flow on the main road. Additionally, on-street parking spaces should not be equipped with ground locks to prevent private occupation. Roads where parking is prohibited may have barriers, posts, or bollards installed on one side. When parking spaces are removed or canceled, all related signs, markings, and management facilities should be promptly cleared to prevent unauthorized parking and ensure road safety. Furthermore, on-street parking spaces should not be set within 200m~300m of off-street public parking lots. Quantitative regulations for on-street parking spaces: The "Urban Road On-Street Parking Space Setting Standards" provides quantitative rules based on road width. For two-way roads, if the actual width exceeds 12 meters, parking spaces can be set on both sides; if between 12m and 8m, only one side is allowed; if less than 8m, no parking spaces are permitted. For one-way roads, if the actual width exceeds 9 meters, parking spaces can be set on both sides; if between 9m and 6m, only one side is allowed; if less than 6m, no parking spaces are permitted. Regarding disabled parking spaces, the standards require that on-street parking spaces should include disabled-accessible spaces, accounting for at least 2% of the total. If there are more than 20 parking spaces, at least one disabled-accessible space should be provided. Parking space marking colors: White: Paid parking spaces; Blue: Free parking spaces; Yellow: Reserved parking spaces; Time-limited parking spaces: Dotted border, 10cm line width; the permitted parking time should be marked inside the border, with numbers 60cm in height. Disabled-accessible parking spaces: Special markings; yellow grid lines on both sides indicate no-parking zones for boarding/alighting, and other vehicles must not occupy these spaces. The road surface should have markings indicating exclusivity. Yellow grid lines should be 120cm wide, with 20cm outer lines and 0cm inner lines at a 45° angle. The outer line length should match the parking space markings. On-street parking spaces should not be set in the following areas: Fire lanes, sections with no-parking signs/markings, or construction zones that obstruct traffic; Roads designated for disaster relief or emergency evacuation; Sidewalks (if set, they must not encroach on blind paths); Near building entrances; Intersections, railway crossings, sharp curves, narrow roads (<4m), bridges, steep slopes, tunnels, or within 50m of such areas; Within 30m of bus stops, emergency stations, gas stations, fire hydrants, or fire stations (except for vehicles using these facilities); Within 20m of intersection channelization zones; Near underground utility access points or within 15m of such areas; Within 200m of off-street parking lot entrances; Near road edges.
