Abstract

Courtesy crossings are elements of the highway, typically provided in more shared street environments, highlighted with coloured surfacing, marked stripes, a raised carriageway and/or narrowing of the road. Whilst not providing a formal pedestrian crossing, they invite pedestrians to cross in a specific place and drivers to let them cross the road safely, out of courtesy. The Chartered Institution of Highways and Transportation and the Department for Transport have recently sought more evidence on such schemes; one of the objectives of this study was to fill this gap. The study has analysed 1,369 observations of pedestrians crossing the road at 12 Sites across the UK, including some ‘shared space’ schemes (such as Bexleyheath, Felixstowe, Poynton, Preston and Swindon). Multilinear regression models have been developed both at aggregate and disaggregate levels, relating courtesy behaviour to 34 explanatory variables. In addition, a before-after analysis testing the effect of the introduction of marked stripes at one site has also been undertaken. This paper presents the results of the models, comments on the statistical significance of factors such as traffic and pedestrian volumes and composition and site infrastructure characteristics; and provide recommendations on how to design courtesy crossings. The presence of stripes had the most significant impact on driver`s courtesy behaviour; it was also observed that the legal requirement to give way to pedestrians at a controlled zebra crossing only affects the pedestrian delay at the crossing. Other relevant design features positively affecting courtesy include the presence of ramps and visual narrowings of the road. On the other hand, where traffic flows include significant numbers of heavy goods vehicles and buses, then vehicles are less likely to give way to pedestrians.
