Session Title: Pedestrian Crossing Safety
Organizer/Moderator: Justin Maderia
Topic A Title: Raised Crosswalks at Multi-Lane Roundabouts: Lessons Learned
Speaker: Letty Schamp
Name, Company, Location: City of Hilliard
Topic A Description: In the summer of 2019, the City of Hilliard constructed raised crosswalks at three roundabouts near schools as part of two different projects: one was a retrofit project and one was on a project where raised crosswalks were planned in the initial design. Each project had two different designs - and construction processes - to attempt to achieve the same goals: reduce vehicle speeds at crosswalks, increase motorist yielding to pedestrians, and address ADA accessibility at multi-lane roundabout crossings.
This presentation will provide details on the two different designs, including 11th hour field changes, and construction challenges. Quantitative before and after speed data was collected, and qualitative observations of motorist and pedestrian behavior were documented to help gauge success of the raised crosswalks. Public perceptions, especially in today's era of social media, will be shared. This presentation will inform public agency officials and designers to help develop best practices for implementation of raised crosswalks at roundabouts in the future.
Topic B Title: Creating Safer Crossings: Using Technology and State of the Practice to Prioritize Pedestrians
Speaker (s): Amy Rosepiler, Jonathan Ryan, and Sally Sharrow
Name, Company, Location: Burgess and Niple, City of Columbus, Toole Design Group
Topic B Description: 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.
Topic C Title: Human Factor Analysis: Design Through the Lenses of Human Behavior
Speaker (s): Yuwen Hou and Patrick Broeren
Name, Company, Location: Arcadis Atlanta, Arcadis Netherlands
Topic C Description: Human behavior is inextricably linked to traffic accidents. Consequently, examining human factors in the infrastructure design process is critical to develop solutions to improve traffic safety and the customer experience. Unlike the traditional traffic and operation analysis when evaluating the overall performance of the transportation system, the Human Factor Analysis considers the performance of the transportation system explicitly from a human behavior point of view. This presentation will delve into the principles of human behaviors and link these principles to safety and operations of roadways. Compared to the reactive, crash based safety approach, the Human Factor Analysis could potentially add another layer to the proactive safety studies that aims at finding design solutions that improve the end-user experience of the roadway system. The presentation will also feature successful case studies overseas and discussion on how this approach can be applied in the United States.
