A decision support tool for accommodating truck turning movements at intersections in walkable communities
Many North American jurisdictions are creating liveable urban environments with a focus on accommodating the needs of pedestrians. In some cases, this has constrained the mobility and accessibility of goods movement in urban areas despite the essential role goods movement plays in sustaining the liveability of the community. Complete Streets design guidelines recommend restrictive geometric design of roadways through narrower lanes and tighter curb radii to promote pedestrian activity, which can exacerbate the accessibility issues of trucks in urban areas. In this research, it was found that the typical three-metre curb radius recommended by Complete Streets guidelines is not always conducive to the right-turn maneuver of a truck (combination or single unit vehicle) and the prescriptive limits of curb radii do not consider the diversity of land use and mobility needs in urban areas. Thus, a decision support tool was designed and developed that integrates land use and transportation mobility to guide the selection and design of urban intersection curb radii that allows the safe and efficient accommodation of trucks and pedestrians. The decision support tool relies on the Freight-Walkability relationship that is measured from a novel Walkability Index and the truck turning activity at an intersection. The Walkability Index extends existing planning-oriented indices by introducing a safety indicator measured by the level of compliance of pedestrian crossing control treatments. Both freight activity and walkability are measured to provide a quantifiable classification of intersections that can be replicated in other jurisdictions specific to their land use, transportation system and freight activity context. The decision support tool provides an integrated engineering and planning solution to address the geometric design trade-offs of trucks and pedestrians in urban areas. This tool can guide transportation engineers and planners to accommodate both pedestrians and trucks through both short-term street-level design ...
