This report presents a Safe System for Intersections (SSI) method that intersection planners and designers can readily implement, that dovetails with the typical U.S. project development process, and that uses commonly available project-level data. The SSI method is presented in the context of a Stage 1 Intersection Control Evaluation (ICE), at the

The preferred design for conventional intersections includes adjacent legs that intersect at 90 degrees. However, there are occasions when physical constraints result in intersection angles less than 90 degrees and thus produce skewed intersections. Skewed intersections may create potential safety and operational problems for both motorists and non

Reduced left-turn conflict intersections are geometric designs that alter how left-turn movements occur. These intersections simplify decision-making for drivers and minimize the potential for higher severity crash types, such as head-on and angle. Two highly effective designs that rely on U-turns to complete certain left-turn movements are known a

Electronic fare payment (EFP) has long been used in the transit industry to facilitate fare collection. These systems, representing an advancement from mechanical or operator-based cash-only systems, can eliminate the need for travelers to have exact change when taking transit. They can also reduce operational costs for agencies, as cash is expensi

The modern roundabout is an intersection with a circular configuration that safely and efficiently moves traffic. Roundabouts feature channelized, curved approaches that reduce vehicle speed, entry yield control that gives right-of-way to circulating traffic, and counterclockwise flow around a central island that minimizes conflict points. The net

HFST is a safety countermeasure intended to restore and maintain pavement friction in wet and dry conditions to reduce crashes. This treatment is especially effective where there is a history of wet-pavement crashes. In Pennsylvania, over 50% of the fatal and serious injury crashes involve a lane departure, and intersection crashes account for 21%

Median barriers are longitudinal barriers that separate opposing traffic on a divided highway and are designed to redirect vehicles striking either side of the barrier. Median barriers significantly reduce the number of cross-median crashes, which are attributed to the relatively high speeds that are typical on divided highways. AASHTO’s Roadside D
