An Evaluation of Driveway Turning Restrictions in Access Management Using Microsimulation
Driveways with direct access especially in commercial areas can create operational as well as safety concerns for both mainline and driveway traffic. In this scenario, left turns in and out of developments are generally the most problematic. The objective of this study was to evaluate the conditions when left turns in and out of such developments become critical and should be restrained. For corner developments, the distance of a driveway from the adjacent intersection is more critical than a mid-block driveway due to the influence of queues. The microscopic simulation models were developed for both corner and midblock sites to analyze the operational impacts of different driveway turning restrictions. The results in terms of delays for the mainline and driveway traffic, and queues for the mainline traffic, were analyzed to recommend ranges for driveway left turns as “can be allowed,” “maybe allowed (with extra caution),” and “should not be allowed”. Microscopic simulation models were developed to quantitatively analyze the impact of varying combinations of mainline and driveway volumes and different corner clearances on the traffic operations; and facilitated in the development of generic guidelines.
