To assess whether traffic-calming features are equitably distributed in the UK.
Cross-sectional database utilising geographical information system (GIS) and population data.
Four large regions in England and Wales, including areas in south Wales, south-west England, east Midlands and Surrey, for which map data were available.
The total proportion of road segments traffic calmed and the likelihood of road segments being traffic calmed by deprivation fifth.
A total of 3.7% of road segments was traffic calmed on 95,791 km of road length. A higher proportion of traffic-calmed road segments was found in deprived areas when population density was taken into account. The odds of traffic calming in the most deprived areas, compared with the most affluent areas, was 2.83 (95% CI 2.815 to 2.835).
High resolution map data can be manipulated within a GIS to enable the distribution of traffic-calming measures to be assessed over large areas. There are very few traffic-calmed roads in any area and there is scope for more. Deprived areas have substantially more traffic calming. Making such data available to the public should be tested as an advocacy tool to increase the provision of traffic-calming features.
评估英国的交通舒缓措施是否公平分配。
利用地理信息系统（GIS）和人口数据进行的横截面数据库。
英格兰和威尔士的四个大区，包括南威尔士、英格兰西南部、东米德兰兹和萨里的一些地区，这些地区都有地图数据。
交通舒缓的道路总比例和按贫困程度划分的道路被交通舒缓的可能性。
在 95791 公里的道路长度上，有 3.7%的道路被交通舒缓。当考虑到人口密度时，在贫困地区发现了更多的交通舒缓道路。与最富裕地区相比，最贫困地区的交通舒缓几率为 2.83（95%置信区间 2.815 至 2.835）。
高分辨率的地图数据可以在 GIS 中进行操作，以便在大面积范围内评估交通舒缓措施的分布情况。任何地区的交通舒缓道路都很少，还有很大的空间可以增加。贫困地区的交通舒缓措施要多得多。应该测试将此类数据提供给公众，作为增加交通舒缓设施的宣传工具。
