Using SS4A to Enhance Opportunity in a Small Texas Community

Texas
With SS4A, cities are able to share the responsibility of maintaining their transportation networks with state DOT by coming up with data-backed justifications for projects that not only enhance safety but also strengthen community. The focus of this poster is on the Town of Pecos City, Texas.

Piloting a Research-Backed Pedestrian Crossing Treatment Toolkit

Delaware
Delaware DOT is testing the pedestrian crossing toolkit developed under NCHRP 03-143. This spreadsheet-based resource incorporates roadway context and yielding data from hundreds of field study sites to help practitioners select treatments for unsignalized intersections and midblock crossings.

Leveraging ARNOLD GIS Data for Nationwide Horizontal Curves Identification

FHWA
This research creates the first complete interstate curve inventory data that identified over 60,000 curves spanning a total 32,000 miles across all 50 states using the automated All Road Network of Linear Referenced Data (ARNOLD) dataset and Geographic Information System (GIS) methodology.

Orange Blossom Trail Pedestrian Safety Improvements

Florida
An $8.7m pedestrian safety project along 1.1 mi of a six-lane arterial in Orlando. Upgrades included raised mid-block crossings, pedestrian hybrid beacons, in-pavement lights, lighting, median fencing, and realigning bus stops with the crosswalks. Only one pedestrian fatality in the four years since completion.

Innovative Rail Crossing and Intersection Safety Improvement

Florida
A highly innovative design utilizing a pear-shaped roundabout to replace three traffic signals and seven rail-gated crossing lanes in a physically constrained area. This $9.5m project located in a community with high numbers of below-poverty residents also added improved pedestrian facilities.

Integrated Pavement Friction Management & Safety Performance Framework

Illinois
This project develops an integrated, network-level pavement friction management framework for Illinois. It transforms friction, traffic, and pavement characteristics into crash-risk measures and integrates them with life-cycle cost analysis to support proactive pavement management decisions.

Advancing Project Identification in Idaho

Idaho
Reliable crash prediction depends on quality data. By combining Idaho and Utah roadway inventory and crash data, ITD improved crash prediction models. This enables Idaho to better identify safety projects and allocate funding using the combined AASHTOWare Safety partner data.
