Academic literature has scant research on sidewalks, and some cities are lacking information to rectify an unprecedented backlog of deteriorating pedestrian infrastructure. A lack of data stymies efforts to understand sidewalks, how they may impact equity, and how cities can prioritize where to begin...

 

The Upper Great Plains Transportation Institute (UGPTI) has built a web-based traffic data analysis tool. This Traffic Analysis Tool uses existing traffic signal control devices to collect data 24 hours per day, 7 days per week, and 365 days per year. The primary purpose of this project was to develop...

 

Recent reconstruction of the Grand Forks transportation network included upgrades of some of the older models of cameras. The MPO intended to: 1) continue utilizing the reconstructed intersections for traffic data collection; 2) utilize available API commands to download traffic data; and 3) minimize...

 

With the recent increase in connectivity in vehicle technologies, connected vehicles (CVs) offer a number of potential improvements (e.g., safety, mobility, environmental efficiency, etc.) to the existing transportation system. However, to maximize these benefits, sufficient market penetration of CV...

 

The statewide driver traffic safety survey provides baseline metrics for the Safety Division and others to use in understanding perceptions and self-reported behaviors related to focus issues. A core set of questions addresses nationally agreed upon priorities, including seat belts, impaired driving...

 

This study examines public opinion toward transit during the COVID-19 pandemic, changes in rider behavior, and responses by transit agencies. This was accomplished through two surveys. First, a survey of transit riders and the public was conducted to examine response to the pandemic. It focused on the...

 

NDDOT requested the Advanced Traffic Analysis Center (ATAC) to conduct before-and-after spot speed studies at three locations along US 85/ND 200. One study was conducted at each of the locations with both northbound/westbound and southbound/eastbound directions of travel observed. Two years later, another...

 

This study examines public opinion toward transit during the COVID-19 pandemic. This was accomplished through topic modeling using social media posts on Twitter. Results showed how discussion regarding public transit changed during the first several months of 2020. This study also shared lessons learned...

 

Precast concrete construction has been proven to be very efficient in bridge engineering, especially in accelerated bridge construction (ABC), where precast concrete components are connected to save time and minimize disruption of traffic. Post-tensioned (PT) concrete structural elements, when combined...

 

The objective of this study was to simulate the stress-displacement behavior of a flexible debris-flow mitigation structure with a three-dimensional finite element model (FEM). Flexible, steel ring-net structures are becoming state-of-practice for debris-flow mitigation in mountainous terrain. These...
