In downtown Columbus, Ohio, the City embarked on a pilot project to assess existing crosswalk treatments, pedestrian safety and visibility at 13 uncontrolled, marked crosswalks on one-way streets. These locations did not have a documented crash history between vehicles and pedestrians but were recognized for their unique locations due to pedestrian volumes, public feedback through the City’s 311 system and observations made by City staff.

Using a MioVision camera, the B&N team collected data that is typically undocumented in standard data collection processes. This information brought added insight to more holistically evaluate the pedestrian and vehicular behavior, driver yielding rates and near-miss data. Using this information, the current state of the practice research and design guides, the B&N team created a “menu” of crosswalk applications to supplement the City’s crosswalk evaluation process.

This presentation will detail the data collection process, including reviewing existing planning agency and City data, technology and field verification, and the process to develop a variety of treatment options for each uncontrolled crossing.

How to strengthen deteriorated T-type pier caps using external post-tensioned bars. Case study will show the District 11 BEL-7-1975 bridge.

Lessons learned and analysis techniques for rating “one of a kind bridges” including damaged bridges, retrofitted rail cars, and other “non-engineered” bridges.

We will present a case study of the use of the USACE SWVM to complete federal permitting and mitigation for a 5.5-mile new alignment highway project in Roane County, West Virginia. Topics will include: 1) project overview, 2) lessons learned from implementing the SWVM protocol from ecological, engineering, and permitting perspectives, 3) cost and time reflection, 4) comparison to current Ohio field methodology and mitigation, and 5) best practices to employ when using the method on large linear projects with more than a few impacts to water resources (this project had impacts to 94 individual streams and 35 wetlands within the 216 acre project area).
