This research aimed to develop an understanding of the safety and operational implications of using the flashing yellow arrow (FYA) in permitted and protected/permitted right turn (PPRT) operations to maximize safety and efficiency. This report includes a review of more than 50 scientific and… Read More

“City Greenways” is a concept proposed as a part of Portland’s 2035 Comprehensive Plan, which calls for a citywide network of park-like pedestrian and bicycle friendly streets crisscrossing the city at roughly three-mile intervals. This research establishes several approaches to measure the… Read More

There have been important advances in non-motorized planning tools in recent years, including the development of the MoPeD pedestrian demand model (Clifton et al., 2013, 2015). This tool and others are increasingly requested by governments and agencies seeking to increase walking activity and… Read More

In 2018 the Federal Highway Administration issued a new guide, Measuring Multimodal Network Connectivity. TREC researchers contributed to the guidebook in partnership with Alta Planning + Design and ICF. The guide provides information on incorporating connectivity measures into state, metropolitan,… Read More

Natural disasters, acts of terrorism, and other emergency incidents can affect multiple jurisdictions simultaneously. Major disasters, such as earthquakes, create large-scale impacts that require outside assistance even for the most prepared local public safety and emergency management… Read More

The 2010 Highway Safety Manual (HSM) provides methods for predicting the number of motor vehicle crashes on various roadway facilities (AASHTO, 2010). However, it includes only a simplistic method for predicting the number of bicycle-related crashes. The research team investigated the bicycle… Read More

There is nationwide interest in supporting sustainable and active transportation modes such as bicycling and walking due to the many benefits associated with them, including reduced congestion, lower emissions and improved health. Although the number of bicyclists is increasing, safety remains a… Read More

Electric bicycle (e-bike) use is a rising phenomenon in North America as a growing number of manufacturers produce a variety of bicycles which can accommodate the needs of diverse populations. With the growth of the e-bike industry, e-bike users are an increasingly integral part of both the… Read More

This proposal builds on the success of NITC’s first Pooled Fund project that created the first national bicycle and pedestrian traffic count archive, named BikePed Portal. The next step for BikePed Portal is to improve its usability for both data providers and data users, specifically… Read More

The Portland Smart Cities UB Mobile PDX proposal is being transformed into a City of Portland Smart cities plan. The original proposal focused strongly on developing mobility solutions that would serve traditionally underserved populations. As the proposal moves into a plan, we intend to deepen our… Read More

Building on the successful scientific computing training program offered by the Software Carpentry (http://www.software-carpentry.org/), the proposed course exposes students in science, engineering, and planning to the best practices in scientific computing through hands-on lab sessions and aims to… Read More

This manual provides a compendium of best practices to help transit and other transportation professionals improve pedestrian and bicycle safety and access to transit, including information on evaluating, planning for, and implementing improvements to pedestrian and bicycle access to transit. It… Read More
