Table 2 Properties of crossing facilities and routes that determine barrier effects

From: Disentangling barrier effects of transport infrastructure: synthesising research for the practice of impact assessment

Properties Description
Crossing facilities
Number of crossing points Slow mobility modes require a higher number of crossing points than fast mobility modes [40, 67]
Height differences Stairs and ramps leading to bridges and tunnels [6, 67]
Integration in the local street network Connection to routes or central mobility strips [131]
Visual conditions Lines of sight and overview at crossing points on roads [22, 87]
Conditions for fear of crime Lighting, visibility, escape opportunities, social surveillance [6, 142]. For a further description, see section “Transport features
Quality Protection from weather, maintenance [6], design and cleanliness [88]
Formal regulation Pedestrian crossings, traffic lights and possibility to manually control these [87]
Crossing routes
Number of crossing routes Utilitarian and recreational routes for slow mobility that cross the transport feature [40]
Connectivity of the street network Mesh width [40]
Density of the street network Network length per hectare or km2 [67]
Attractivity Planning, design, signage, cultural-historic value, level of traffic safety [6, 40]
