Entry gets activated and shows the empty parking slot. If there is no slots available for parking It shows the message that all slots are full and driver have to wait for some time. The original design required the use of sensors mounted in road. This system is usable for the parking slot seeker to know the exact empty parking slot. An Automated Parking System or APS is a mechanical system that moves cars from the entry to an available parking space. It uses multiple levels and stacks cars vertically to use as less land as possible to park as many cars as possible. It’s entirely automatic and doesn’t require any staff. Automated Parking Systems are sometimes also.
A parking space is a location that is designated for parking, either paved or unpaved. It can be in a parking garage, in a parking lot or on a city street. The space may be delineated by road surface markings. The automobile fits inside the space, either by parallel parking, perpendicular parking or angled parking.
Depending on the location of the parking space, the time allowed to park may be fixed by regulation, and a fee may be required to use the parking space. It may be designated for free parking. When the demand for spaces outstrips supply vehicles may overspill park onto the sidewalk, grass verges and other places which were not designed for the purpose.[1]
Patterns[edit]
For most motorised vehicles, there are three commonly used arrangements of parking spaces—parallel parking, perpendicular parking, and angle parking. These are self-park configurations where the vehicle driver is able to access the parking independently.
Parallel parking[edit]
With parallel parking of cars, these are arranged in a line, with the front bumper of one car facing the back bumper of an adjacent one. This is done parallel to a curb, when one is provided. Parallel parking is the most common mode of streetside parking for cars. It may also be used in parking lots and parking structures, but usually only to supplement parking spaces that use the other modes.
Perpendicular parking[edit]
With perpendicular parking, also known as bay parking, cars are parked side to side, perpendicular to an aisle, curb, or wall. This type of car parking fits more cars per length of road (or curb) than parallel parking, and is therefore commonly used in car parking lots and car parking structures.
Often, in car parking lots using perpendicular parking, two rows of parking spaces may be arranged front to front, with aisles in between. If no other cars are blocking, a driver may perform a 'pullthrough' by driving through one parking space into the connecting space to avoid having to reverse out of a parking space upon their return.
Sometimes, a single row of perpendicular car parking spaces is marked in the center of a street. This arrangement eliminates reversing from the manoeuvre; cars are required to drive in forwards and drive out forwards.
Angle parking/echelon parking[edit]
Angle parking, known as echelon parking in Britain, is similar to perpendicular parking for these vehicles, except that cars are arranged at an angle to the aisle (an acute angle with the direction of approach). The gentler turn allows easier and quicker parking, narrower aisles, and thus higher density than perpendicular parking. While in theory the aisles are one-way, in practice they are typically wide enough to allow two cars to pass slowly when drivers go down the aisles the wrong way.
Angle parking is very common in car parking lots. It may also be used in streetside car parking in the U.S. when there is more width available for car parking than would be needed for parallel parking of cars, as it creates a larger number of parking spaces. Some cities have utilized angled parking on-street (as compared to off-street parking facilities). This has been done mostly in residential, retail and mixed use areas where additional parking compared to parallel parking is desired and traffic volumes are lower. Most angled parking is design in a head-in configuration while a few cities (Seattle, Portland, Baltimore, and Indianapolis are examples) have some back-in angled parking (typically on hills or low traffic volume streets).
Angle parking is considered dangerous by cycling organisations, especially in the head-in configuration, but unwelcome in either form. When comparing to parallel parking:
- There is a significant risk to cyclists from vehicles reversing out, as approaching bicycles are in the blind spot of the reversing and turning vehicles.[2]
- Longer vehicles project further into the road; this can inconvenience/endanger other road users,
- The 'surplus' road space which enables angle parking could also be used for bicycle lanes.
Hence organisations such as the Cyclists Touring Club are usually opposed to all proposed echelon parking schemes, though there are some alternatives, such as back-in angle parking (slanted the 'wrong' way, with the driver reversing into the space, rather than reversing out), which can overcome many of the issues of safety.
Other parking methods[edit]
Besides these basic modes of motor vehicle parking, there are instances where a more ad hoc approach to arranging motor vehicles is appropriate. For example, in parts of some large cities, such as Chicago and Bangalore, where land is expensive and therefore parking space is at a premium, there are formal and informal parking lots for motor vehicles where the driver leaves the keys to the vehicle with an attendant who arranges vehicles so as to maximize the number of vehicles that can be parked in the lot. Vehicles may be packed up to five vehicles deep in combinations of perpendicular and/or parallel parking with limited circulation aisles for the parking attendant. Such arrangements are known as attendant parking. When the lot or facility is provided to serve the customers of a business, it is considered valet parking.
Inner city parking lots are often temporary, the operators renting land which is vacant pending the construction of a new office building. Some inner city lots are equipped with individual lifts, allowing cars to be stored above each other.
Another ad hoc arrangement is tandem parking. This is sometimes done with residential motor vehicle parking where two motor vehicles park nose-to-end in tandem. The first motor vehicle does not have independent access, and the second motor vehicle must move to provide access. As with attendant parking, the purpose is to maximize the number of motor vehicles that can park in a limited space. Formalised tandem parking will sometimes be sanctioned by local planning authorities for staff parking arrangements require additional parking in limited spaces.
Marks and space size[edit]
Parking Slot Measurement System Calculator
In parking lots (car parks in British English), parking is allowed only where marked.[3]
In the US, minimum width standards of parking spaces usually range from 8.5 to 9.0 feet (2.6–2.7 m). Angled and perpendicular spaces may need to be wide to allow doors to open, while parallel parking spots may be narrower on low-traffic neighborhood streets.
Because the boundary between parking space and driving area is not always well-defined, the length of a parking space is more difficult to establish. However, most angled and perpendicular spaces are considered to be between 10 and 18 feet (3.0–5.5 m) in length. In the United States, due to vehicles being larger on average than some other countries[citation needed], a parking space 10 feet (3.0 m) deep is uncommon and most parking spaces will be within 16 to 20 feet (4.9–6.1 m), with 19 feet (5.8 m) feet deep being the standard DOT recommended depth for standard perpendicular parking[citation needed]. Parallel parking spaces typically range from 20 to 24 feet (6.1–7.3 m) long.
During construction, the specific dimensions of a parking space are decided by a variety of factors. A high cost of land will encourage smaller dimensions and the introduction of compact spaces.[4] Many garages and parking lots have spaces designated for a Compact car only. These spaces are narrower than traditional spaces, thus allowing more cars to park.[5]
According to French standard 'Norme NF P 91-100', minimum width of parking spaces range from 2.20 to 2.30 metres (7.2–7.5 ft) (See fr:Marquage du stationnement en France). Narrow parking spaces such as in Vevey, Switzerland, might make opening the door difficult in a larger vehicle.
Larger cars are an issue when the size of the bay is fixed. Automobile associations warn of this issue.[6] A Swiss Association regulating parking space wants to consider this issue for 2016. [needs update]
In the United Kingdom, the recommended standard parallel bay size is 2.4 metres (7.9 ft) wide by 4.8 metres (16 ft) long. Recently there has been some controversy about most UK parking spaces being too small to fit modern cars, which have grown significantly since standards were set decades ago.[7]
In Australia, the dimensions are defined in AS2890 and are 2.4 m wide by 5.4 m long.[8]
Barriers[edit]
Parking Slot Measurement System Chart
Parking spaces commonly contain a parking chock (wheel stop), which is used to prevent cars from pulling too far into the space and
- obstructing a neighboring parking space, curb, or sidewalk.
- contacting with and then damaging a building wall.
This barrier is usually made of concrete and will normally be a horizontal bar to stop the tires from moving forward or a vertical bar that may cause damage to the vehicle if contact is made. In a parking garage, the barrier will often be a concrete wall.
Parking spaces for the disabled[edit]
Some parking spaces are reserved as handicapped parking, for individuals with disabilities. Handicapped parking spaces are typically marked with the International Symbol of Access, though in practice, the design of the symbol varies widely.[9]
In the United States the Access Board provides guidelines on parking spaces.[10][11]
Women's parking spaces[edit]
In some countries, women's parking spaces have been established in more visible spots to reduce the chance of sexual attacks,[12] facilitate parking for women, or to provide spaces that are closer to shopping centers or employment.[13][14]
US curb markings[edit]
Curb markings in the United States are prescribed by the Manual of Uniform Traffic Control Devices (MUTCD).[15] Local highway agencies may prescribe special colors for curb markings to supplement standard signs for parking regulation. California has designated an array of colors for curb regulations. A white curb designates passenger pick up or drop off. The green curb is for time limited parking. The yellow curb is for loading, and the blue curb is for disabled persons with proper vehicle identification. The red curb is for emergency vehicles only - fire lanes (no stopping, standing, or parking). In Oregon and Florida, the yellow curb is utilized to indicate no parking. In Georgia either red or yellow can be used to indicate no parking. In Seattle, Washington, alternating red and yellow curb markings indicate a bus stop.

When a business or State or local government restripes parking spaces in a parking lot or parking structure (parking facilities), it must provide accessible parking spaces as required by the 2010 ADA Standards for Accessible Design (2010 Standards).
In addition, businesses or privately owned facilities that provide goods or services to the public have a continuing ADA obligation to remove barriers to access in existing parking facilities when it is readily achievable to do so. Because restriping is relatively inexpensive, it is readily achievable in most cases. State and local government facilities also have an ongoing ADA obligation to make their programs accessible, which can require providing accessible parking.
This compliance brief provides information about the features of accessible car and van parking spaces and how many accessible spaces are required when parking facilities are restriped.
One of six accessible parking spaces,
but always at least one, must be van-accessible.
The required number of accessible parking spaces must be calculated separately for each parking facility, not calculated based on the total number of parking spaces provided on a site. One of six (or fraction of six) accessible parking spaces, but always at least one, must be van accessible.
Parking for hospital outpatient facilities, rehabilitation facilities, outpatient physical therapy facilities or residential facilities have substantially different requirements for accessibility (see 2010 Standards 208.2).

Location
Accessible parking spaces must be located on the shortest accessible route of travel to an accessible facility entrance. Where buildings have multiple accessible entrances with adjacent parking, the accessible parking spaces must be dispersed and located closest to the accessible entrances.
When accessible parking spaces are added in an existing parking lot or structure, locate the spaces on the most level ground close to the accessible entrance. An accessible route must always be provided from the accessible parking to the accessible entrance. An accessible route never has curbs or stairs, must be at least 3 feet wide, and has a firm, stable, slip-resistant surface. The slope along the accessible route should not be greater than 1:12 in the direction of travel.
Accessible parking spaces may be clustered in one or more facilities if equivalent or greater accessibility is provided in terms of distance from the accessible entrance, parking fees, and convenience. Van-accessible parking spaces located in parking garages may be clustered on one floor (to accommodate the 98-inch minimum vertical height requirement).
Features of Accessible Parking Spaces
Accessible Parking Spaces with
60-inch Minimum Width Access Aisle for Cars
Notes:
1. Parking space identification sign with the international symbol of accessibility complying with 703.7.2.1 mounted 60 inches minimum above the ground surface measured to the bottom of the sign.
2. If the accessible route is located in front of the parking space, install wheel stops to keep vehicles from reducing the clear width of the accessible route below 36 inches.
3. Two parking spaces may share an access aisle except for angled parking spaces (see below).
Access aisle width is at least 60 inches, must be at the same level and the same length as the adjacent parking space(s) it serves, maximum slope in all directions is 1:48, and access aisle must connect to an accessible route to the building. Ramps must not extend into the access aisle.
4. Parking space shall be 96 inches wide minimum, marked to define the width, and maximum slope in all directions is 1:48.
5. Boundary of the access aisle must be clearly marked so as to discourage parking in it. (State or local laws may address the color and manner that parking spaces and access aisles are marked.)
Additional Notes:
Where parking spaces are marked with lines, width measurements of parking spaces and access aisles are to centerlines, except for the end space which may include the full width of the line.
Parking Slot Measurement System Definition
Access aisles may be located on either side of the parking space except for angled van parking spaces which must have access aisles located on the passenger side of the parking spaces.
Additional Features of Van-Accessible Parking Spaces
Van-accessible parking spaces incorporate the features of accessible parking spaces on the previous page and require the following additional features: a 'van accessible' designation on the sign; different widths for the van parking space or the access aisle; and at least 98 inches of vertical clearance for the van parking space, access aisle, and vehicular route to and from the van-accessible space. The first image below shows a van-accessible space with a 60-inch minimum width access aisle. The second image shows a van-accessible space with a 96-inch minimum width access aisle. Both configurations are permitted and requirements for van-accessible signage and vertical clearance apply to both configurations.
Van-Accessible Parking Space with
60-inch Minimum Width Access Aisle
Notes (for illustrations above and below):
1. Parking space identification sign with the international symbol of accessibility and designation, 'van accessible.' Note, where four or fewer parking spaces are provided on a site, a sign identifying the accessible space, which must be van-accessible, is not required.
