The objective of this study is to obtain additional research-based insight into how driveway design and location impact vehicular, bicycle, and pedestrian safety. The research team will evaluate the impact of driveway type and location along major roadway corridors and in the vicinity of interchanges on vehicular, and bicycle- and pedestrian-involved crashes. This will include issues such as the types of turning movements allowed (e.g., right in /right out, right-in only, right-out only, left-in only, left-out only, full access), other design characteristics (e.g., spacing, turn lane length, functional area/corner clearance, speed, location of sidewalk, etc.) and driveway volumes. A related objective is to translate the findings into guidance that will help planners and engineers achieve a significant reduction in fatalities and serious injuries on public roads for all roadway users. The study will identify any need for changes to the access management guidance provided to the Districts for access permit applications, to ensure improved safety outcomes for all travel modes in commercial driveway access permitting and mitigation decisions. It will also assess whether additional guidance is needed for review of requests for new or modified interchanges and for interchange area access management planning. |
