Emily Guenther Zach Olson Laura Scott Cameron Wein Locating Unsafe Areas for Cyclists and Pedestrians in Monona, Wisconsin Geography 578 Final Presentation
Study Area Population of approximately 8000 residents Four square miles of residential homes, commercial properties, and green space surrounded by the City of Madison Because of its unique geography connecting East Madison to the Isthmus, Monona faces challenges in managing high traffic volume on its three main transportation corridors
Study Area
Background: UniverCity Alliance The City of Monona has partnered with the University of Wisconsin-Madison to explore sustainable development across four areas: Housing and Development, Community Media, Parks & Recreation, and Transportation Our role: To assist planners to better understand existing transportation infrastructure, with an emphasis on pedestrian and cyclist safety. Why is this important? In 2015, motor- vehicle related crashes claimed the lives of 5376 pedestrians and injured 70,000. Motor-vehicle-related crashes injured 45,000 bikers and claimed the lives of 818. (National Highway Traffic Safety Administration, 2017)
Background “Livable Communities” is a relatively new concept in urban planning that encompasses a wide range of characteristics that describe a general quality of life Elements: variety of housing types, quality health facilities and schools, reliable public transportation, access to shopping, recreation and culture, physical environment that fosters walking and cycling (AARP Public Policy Institute, 2015) Benefits of walkable communities: reduced carbon emissions and vehicle related air and noise pollution, physical health and well-being, increased economic activity, higher home values
What are the unsafe areas for pedestrians and cyclists while traversing Monona? Question
Methodology Identify five factors that affect designation as unsafe: Traffic Speed Traffic Volume Absence of Bike Lane/Sidewalk Slope Previous Accidents
Methodology 1. Identify unsafe areas for each data layer. 2. Assign scores of “0” (low risk) or “1” (high risk). 3. Merge data layers to assess total risk.
Traffic Speed Traffic speeds derived from existing roadway data Threshold: Speeds equal to or greater than 30 miles per hour were designated as potentially unsafe Areas of potential risk: Monona Drive, Stoughton Road, Broadway, Beltline Highway* Traffic Speed
Traffic Volume Traffic volume data was obtained from the Wisconsin DOT Interactive Traffic Map Approximately 30 data points were added to existing road layer Threshold: Locations with greater then 4000 daily vehicles were designated as potentially unsafe Areas of potential risk: Monona Drive, Stoughton Road, Broadway, Nichols Road, Bridge Road, Winnequah Road (south end) Add map
Bike Routes Bike routes defined as dedicated bike paths, bike lanes, or scenic trails Corridors with established bike routes were scored “0” and those without bike routes were scored “1”
Sidewalks Lack of sidewalks creates a potentially dangerous environment for pedestrians Areas with sidewalks were scored “0” and areas lacking sidewalks were scored “1”
Slope Contour map converted into DEM via interpolation Calculated gradients from DEM Established threshold of 7% grade( four degrees) Locations greater or equal to a 7% gradient were determined to pose a potential risk Reclassed to assign values of “1” to sites over 7% and sites less than 7% were assigned a value of “0”
Previous Accidents 22 vehicle vs. bike accidents 10 vehicle vs. pedestrian accidents Accidents were officially recorded from 2010-2016
Results: Pedestrian Safety Score 0-3
Results: Pedestrian Safety Majority of Pedestrian Accidents along Monona Dr. 1 on road with score of 0
Results: Bicycle Safety Score 0-3
Results: Bicycle Safety Winnequah Road and Winnequah Trail are considered to have 0 risk Scenic bike routes without any bike infrastructure
Results: Bike Accidents Many Accidents on Monona Drive
Key Conclusions Speed and Volume are the most dangerous factors for both Pedestrians and Bicyclists Bike Infrastructure need to be added to shared bike path
Future Considerations Affect of signage on pedestrian safety Obstructions and condition of pavement Crosswalks Analysis using a more nuanced scoring system
