Interchange Deceleration Lane Design Based on Naturalistic Driving Speed and Deceleration Rates

Dan Xu (1st Place Poster Award Winner) and Chennan Xue

(Poster updated 8/1/2018)

The Green Book provides the minimum lengths of deceleration lanes. The length recommendations provided by the 2011 edition are similar to the documents published in 1965, which were based on the data collected in the 1930s and had not been updated. (Fitzpatrick et al., 2012; Abdelnaby, 2014) Data was obtained from NDS dataset, including Video and Time Series Report.

FHWA/Safety/Intersection/Intersection Safety

Imagine a multilane urban/suburban roadway where traffic is heavy, yet moves well; accommodates drivers, pedestrians, and bicyclists; allows easy entry to and exit from businesses and other destinations; and has fewer crashes and other conflicts. Chances are this road is benefitting from corridor access management, a strategy that seeks an appropriate balance between the safety and mobility of a roadway facility with the access needs of adjacent land uses.

These guidelines do not establish ramp and interchange spacing standards. Rather they provide a process and criteria for assessing spacing in a given context to assist planners and designers in considering the feasibility of new or rebuilt interchanges and ramps. Interchange spacing is defined as the distance between the centerlines of successive crossroads with interchanges on a freeway.
