ABSTRACT
This presentation summarizes preliminary analyses of some factors related to fatal bicyclist crashes. It focuses on urbanized counties in California, Nevada, Oregon, and Washington for the years 2008-2018. Key variables analyzed include state and county, crash location (at intersection, on roadway, on shoulder, etc.) and lighting conditions (day/night). The National Highway Traffic and Safety Administration’s (NHTSA) Fatality Analysis Reporting System (FARS)’s data were used for the analyses. Results show commonalities and differences across the counties. In Nevada, Clark and Washoe counties had most of their crashes during daylight conditions, on the roadway. In California, results vary across the state. Yolo County had most of their crashes on the roadway, and not intersection related. San Diego County had half of their crashes under daylight conditions, on the roadway. San Francisco County had most of their crashes under daylight conditions, on the roadway, and at an intersection. Sacramento County had half of their crashes under daylight conditions, on the roadway, and not at an intersection. Los Angeles County had half of their crashes under daylight conditions, on the roadway. Multnomah County, Oregon had most of their crashes under daylight conditions, on the roadway. King County, Washington had most of their crashes under daylight conditions, on the roadway, with a slight majority at an intersection. The results indicate that other factors such as roadway and bicyclist characteristics also need to be integrated in the analyses. These will be explored next to help develop and deploy appropriate countermeasures to enhance bicyclist safety.

  1. Hi, Allyson,
    Great presentation overall; congratulations! I am really intrigued by the clear and visible trend in your demographic data which reveals the 45 to 54 years of age category as the highest number of fatalities. Do you have any insights on why this might be the case? And what factors underline this “aged” patterning? Thank you!

    1. Hi Dr. Atici!

      Thank you very much for your feedback! In the early stages of the project, there were a few articles that pointed to there being a possible correlation between age and biological sex of cyclists killed in fatal crashes. If I were to hypothesize a guess, or shoot something “off the cuff”, perhaps this could be due to in increase in popularity of cycling in the first half of the early 2000s- a la Lance Armstrong and Tour de France? Or maybe this is a physical activity being pushed by many primary care physicians as a healthy and safe way for adults to exercise? I am still in the process of gathering all demographic data for the areas studied, but it is definitely a thought-provoking observation.

  2. Allyson,
    Great job on your Podium Presentation. I thought that your slide presentation and presentation as a whole was very organized and straight to the point. I also thought that you did an extremely good job at providing details and information about crashes and statistics. In addition, it was a great idea to include a personal story, as well as share how this problem does not only affect Nevada, but other states around America. The only advice I would give is to make your voice a little less monotone and provide more emphasis. Your voice is very clear and your words were pronounced well, but a little more emphasis could go a long way. Great job!

    1. Hi Adam!

      Thank you so much for your feedback, and taking time to view my presentation. I do agree- I think vocal variety would have helped to emphasize certain points. I will look to include these changes in the future.

  3. Hello! Thank you for coming to my page to view my presentation. As always, I look forward to your feedback, both on content and presentation of the material. I am excited to discussing this further with all of you soon!
