In today's urban landscapes, bike and pedestrian planning is pivotal for fostering sustainable, healthy, and safe communities. By prioritizing comprehensive bike and pedestrian infrastructure, communities can create resilient transportation networks that support diverse mobility needs and promote social equality, public health, and the environment. This blog explores the significance of bike and pedestrian planning and examines how AI-powered geospatial data is revolutionizing these efforts to foster safer and more navigable cities.
The importance of bike and pedestrian planning
Active transportation, which refers to human-powered travel methods such as cycling and walking, makes up more than half of trips in the US that are under three miles. However, many Americans lack access to safe and convenient pedestrian and biking networks, particularly in low-income communities where residents are more dependent on these modes of travel. The US Department of Transportation (DOT) reports that pedestrian and cyclist fatalities constitute nearly 20% of all traffic deaths annually. It is also estimated that each year, over 76,000 pedestrians and 47,000 bicyclists are injured in roadway crashes. Alarmingly, these numbers have been on the rise in recent years.

The increase in traffic incidents has caused communities across the US to implement Vision Zero plans in hopes of eliminating all traffic-related fatalities and injuries. Bike and pedestrian planning is integral to achieving Vision Zero goals by prioritizing infrastructure improvements that enhance safety for cyclists and pedestrians. This includes creating separated bike lanes, improving crosswalk visibility and accessibility, and more. By integrating bike and pedestrian planning into Vision Zero strategies, communities can create environments that prioritize the safety and well-being of all road users, ultimately contributing to the goal of eliminating traffic-related fatalities and injuries.
Addressing the $7 billion gap in bike and pedestrian infrastructure
A significant factor contributing to pedestrian and cyclist deaths and injuries is the lack of sidewalks, crosswalks, bike paths, and other deficiencies in transportation infrastructure. In fact, there is an estimated $7 billion in unmet needs for active transportation networks nationwide.
In both urban and rural areas across the country, incomplete or poorly connected sidewalks and bike lanes force pedestrians and cyclists to share roadways with vehicles, significantly increasing the risk of accidents. The issue is more than just the lack of infrastructure; problems with existing infrastructure also pose challenges for cyclists and pedestrians. For instance, planting strips and street trees can obstruct sidewalks and bike lanes, creating hazards for users, especially those with mobility impairments. Additionally, poorly designed crosswalks and intersections further contribute to accidents involving pedestrians and cyclists.
Fortunately, new technology has emerged to provide Metropolitan Planning Organizations (MPOs) and DOTs with the comprehensive, accurate, and up-to-date geospatial data needed to identify infrastructure issues and prioritize improvements.

Sidewalk gap analysis
According to the Federal Highway Administration (FHWA), roadways without sidewalks are more than twice as likely to experience pedestrian crashes compared to locations with sidewalks on both sides of the street, and installing walkways separated from travel lanes has been shown to significantly mitigate pedestrian crashes on roadways, reducing incidents by up to 88%. These statistics underscore the significant impact of connected sidewalk networks in mitigating risks for pedestrians, reducing potential conflicts with vehicular traffic, and fostering safer environments for walking. By conducting thorough sidewalk gap analyses, municipalities can identify gaps in the sidewalk network and prioritize targeted improvements to ensure safer and more accessible pathways for all users. These proactive measures not only improve safety but also contribute to the overall livability of communities.
When it comes to fostering safe community connections, the width of sidewalks is also a critical factor. The Americans with Disabilities Act (ADA) establishes specific standards for sidewalks, including minimum width requirements, to ensure accessibility for individuals with disabilities. Adhering to these standards is essential for creating inclusive and navigable public spaces. Narrow sidewalks can significantly hinder accessibility, posing challenges for wheelchair users and creating potential safety hazards. By assessing sidewalk widths in conjunction with planting strip data, communities can identify pinch points and locate areas where widening is necessary to enhance accessibility and safety.
Examining pedestrian mobility in Chicago
In 2022, the Chicago Metropolitan Agency for Planning (CMAP) was looking for a comprehensive understanding of sidewalk infrastructure in their region. Initially, the team decided to manually identify and map the region’s sidewalk inventory. This laborious process required nine full-time staff members and took over a year to complete. Recognizing the high cost of repeating this method, they sought a more efficient solution and turned to Ecopia. In just six weeks, Ecopia delivered individual vector features that included sidewalk centerlines, edges, and width attributes across the entire 30,000-mile area. This solution saved over 40 weeks of time and substantial salary costs for ten employees. Additionally, it provided the State and MPOs in Illinois with a scalable and repeatable process for obtaining and maintaining highly accurate data, crucial for prioritizing and addressing areas for improvement to ensure safe, navigable pathways for all pedestrians.

Bicycle infrastructure gap analysis
Similar to analyzing gaps in sidewalk infrastructure, bike gap analysis is essential for municipalities aiming to improve cycling infrastructure and encourage active transportation. Detailed geospatial data plays a crucial role in this process by providing comprehensive insights into existing bike lanes, gaps in the network, and areas where infrastructure improvements are needed. This data allows planners to prioritize investments in bike infrastructure, such as building new lanes or connecting existing ones to create a cohesive network. Moreover, geospatial data aids in assessing the accessibility and usability of bike lanes for cyclists of all abilities, ensuring that infrastructure enhancements meet diverse community needs. By leveraging detailed geospatial data, municipalities can foster a bike-friendly environment that promotes sustainable mobility and community health.

Impedance factors
Impedance factors that obstruct sidewalks and bike lanes pose significant challenges to the mobility and safety of pedestrians and cyclists. Access to up-to-date geospatial data can help municipalities identify and mitigate these issues. For example, street trees, while beneficial for creating shade and enhancing aesthetics, can create barriers if improperly placed or poorly maintained, causing narrow or uneven pathways that limit pedestrian passage. Similarly, planting strips intended for greenery can encroach upon sidewalk space or bicycle lanes, potentially forcing pedestrians and cyclists into the path of vehicle traffic.
By leveraging geospatial data, municipalities can effectively map and analyze the locations and conditions of street trees, planting strips, and other impedance factors. This enables informed decision-making to help ensure that sidewalks and bike lanes remain accessible, safe, and conducive to pedestrian activity. Given that urban environments evolve over time, keeping this data up-to-date is essential for proactive management, allowing cities to identify and address impediments promptly.
