Crash Risk and Access Spacing on Two-Lane and Multi-Lane Highways
Hitesh Chawla; Peter T. Savolainen, Ph.D., P.E.
INTRODUCTION
Effective access management is essential to mitigating traffic crash risks. Most of the crashes occurring near access points are a result of conflicts between multiple vehicles. This motivates the development of guidelines for access spacing. To this end, this study evaluated the relationship between crash risk and access point spacing on two-lane and multi-lane highways across the state of Iowa.
Access Management to Reduce Wrong-Way (WWD) Driving on Alabama Divided Highways
Beijia Zhang
A divided highway is considered as a highway with physical separation, and the side streets are its access points in this study.
WWD crashes are more possible than other kinds crashes to result in fatal or incapacitating injuries. The majority of previous studies are focused on freeways instead of divided highways.
112 WWD crashes were identified in Alabama divided highways from 2009 to 2013.
Interchange Deceleration Lane Design Based on Naturalistic Driving Speed and Deceleration Rates

(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.
Access Control and Geometric Features at the Interchange Terminals with a large number of Wrong-Way Incidents: Case Studies in Alabama
Md Atiquzzaman (Tie for 2nd Place Award)
Although wrong-way driving crashes are rare, they draw a lot of attention due to their severe outcomes. Two interchange terminals were monitored by video camera for 48 hours on a typical weekend. The two locations experienced 10 and 17 WWD incidents.
Objectives
A Probabilistic Model to Predict Intermittent Sight Distance Obstruction at Unsignalized Intersections on High-Speed Rural Divided Highways
Chennan Xue and Dan Xu
Minor-road left-turn vehicles’ views are likely to be blocked by major-road right-turn vehicles on the conventional right-turn lane at unsignalized intersections.
