A Population Approach to Transportation Planning: Reducing Exposure to Motor-Vehicles
Figure 3
Approaches to address safety at intersections using the traditional high-risk approach (a) and the population approach (b). Note: the figure is adapted from: US Department of transportation, Federal Highway Administration [32]. Signalized intersection: Informational guide. Publication no. FHWA-HRT-04-091. Arrows represent the hypothetical change in the number of collisions per year associated with high-risk (a) and population (b) approaches.
(a) Potential effect of reducing collisions rate at targeted “deviant” intersections
(b) Potential effect of a global reduction in exposure to traffic volume at intersections
