|
|
By reducing delays and improving reliability. |
| 
|
|
By ensuring residents have parking spaces and social areas, and streets are not congested with other traffic parked or searching for spaces. |
| 
|
|
By reducing air and noise pollution, and visual intrusion. |
| 
|
/ |
Parking controls which prevent obstructions for pedestrians can bring benefits of accessibility and improved safety, especially for people with limited mobility and for children.
Controls that restrict supply mean that demand is satisfied on a first come first served basis, which may not coincide with priority of need. Duration and time of day controls may also exclude those with important needs. Permit only areas exclude those not eligible for permits, which can be problematic where no alternatives are provided. |
| 
|
|
By controlling parking in unsafe locations. |
| 
|
|
Where reduced congestion and pollution improves environmental quality, and neighbouring parking policies are not contradictory. |
| 
|
|
Cost of operations. Revenue may be generated through parking charges. |

| Congestion-related delay |
|
Where search traffic is reduced and/or alternative modes are easier to use. |
| Congestion-related unreliability |
|
Where search traffic is reduced and/or alternative modes are easier to use. |
| Community severance |
|
Where search traffic is reduced. |
| Visual intrusion |
/ |
Less on-street parking will have a positive contribution. More off-street parking at a new out of town site or multistorey will have a negative impact. |
| Lack of amenity |
|
Where it becomes easier to access amenities and hence, more worth while providing them. |
| Global warming |
|
Where search traffic is reduced. |
| Local air pollution |
|
Where search traffic is reduced. |
| Noise |
|
Where search traffic is reduced. |
| Reduction of green space |
/ |
Positive benefit where controls against inappropriate parking on green space is enforced/ Negative benefit where new off street parking is provided out of town |
| Damage to environmentally sensitive
sites |
/ |
Positive benefit where controls against inappropriate parking on or near environmentally sensitive sites are enforced/ Negative benefit where new off street parking is provided out of town |
| Poor accessibility for those without
a car and those with mobility impairments |
|
Both groups should benefit where parking controls are well designed i.e. non-essential traffic is kept of the road making access by alternative means easier, and there is more and better located provision for disabled drivers. |
| Disproportionate disadvantaging of particular
social or geographic groups |
/ |
As above, if appropriate provision for people with disabilities or in emergency. Negative if not appropriate provision. |
| Number, severity and risk of accidents
|
|
In appropriate parking increases risks of collision especially for vulnerable road users. Further through less search traffic, as drivers searching for spaces may be on unfamiliar roads or have their attention districted by the search. |
| Suppression of the potential for economic
activity in the area |
|
Where neighbouring parking policies are not contradictory. |
