Elements of pedestrian-friendly design

• Pedestrian-friendly design focuses on creating safe, comfortable, and inviting environments that encourage walking
• Key elements include well-designed sidewalks, crosswalks, and public spaces that prioritize pedestrian mobility
• Successful pedestrian-friendly design requires a holistic approach that considers the needs of all users, including children, seniors, and people with disabilities

Safe and accessible sidewalks

• Sidewalks should be wide enough to accommodate pedestrian volumes and allow for comfortable passing (minimum 5 feet)
• Smooth, even surfaces and gentle slopes ensure accessibility for wheelchairs, strollers, and mobility devices
• Clear sightlines and adequate lighting improve safety and security for pedestrians
• Sidewalks should be buffered from traffic with landscaping, street furniture, or on-street parking

Traffic calming measures

• Traffic calming uses physical design to slow vehicle speeds and prioritize pedestrian safety (speed humps, chicanes)
• Narrower travel lanes and tighter turning radii discourage speeding and make streets more pedestrian-friendly
• Raised crosswalks and intersections improve visibility and give pedestrians priority over vehicles
• Traffic calming can be combined with streetscaping elements like planters, bollards, and textured pavements

Pedestrian-oriented street lighting

• Adequate lighting is essential for pedestrian safety and comfort, especially at night and in underserved areas
• Pedestrian-scale lighting (12-15 feet high) creates a more intimate and human-scaled environment than tall, widely-spaced streetlights
• Lighting should be focused on sidewalks, crosswalks, and public spaces rather than just the roadway
• Energy-efficient LED lighting can reduce costs and minimize light pollution while improving visibility

Attractive landscaping and street furniture

• Street trees provide shade, reduce urban heat, and create a more pleasant walking environment
• Landscaping elements like planters, green walls, and rain gardens add visual interest and ecological benefits
• Benches, trash receptacles, and bike racks make streets more functional and inviting for pedestrians
• Public art, wayfinding signage, and other design elements can enhance the character and identity of a neighborhood

Walkable neighborhood characteristics

• Walkable neighborhoods are designed to support pedestrian activity and reduce dependence on cars for daily needs
• They typically feature a mix of land uses, compact development patterns, and a well-connected street network
• Walkable neighborhoods prioritize human-scale design and create a sense of place through distinctive architecture and public spaces

Mixed-use development

• Mixed-use development combines residential, commercial, and institutional uses within the same building or block
• This land use pattern puts housing, jobs, shops, and services within walking distance of each other
• Mixed-use development can increase pedestrian activity, support local businesses, and reduce the need for car trips
• Examples include main street districts, transit-oriented developments, and live-work units

Compact and connected street network

• A dense, grid-like street network with short blocks and frequent intersections makes walking more direct and efficient
• Connected streets distribute traffic and provide multiple routes for pedestrians, improving accessibility
• Cul-de-sacs and dead-end streets are minimized to prevent pedestrian barriers and encourage through-movement
• Alleys and mid-block pedestrian paths can further enhance connectivity and create intimate, human-scaled spaces

Proximity to amenities and services

• Walkable neighborhoods provide easy access to daily needs like grocery stores, schools, parks, and transit stops
• Amenities should be located within a 5-10 minute walk (1/4 to 1/2 mile) of most residences
• Clustering complementary uses together (cafes near parks, daycares near schools) can encourage multipurpose trips on foot
• Proximity to amenities reduces the need for driving and supports local economic development

Human-scale architecture and design

• Buildings in walkable neighborhoods are typically oriented towards the street, with active ground-floor uses and frequent entrances
• Architectural details like awnings, storefronts, and porches create a engaging and pedestrian-friendly streetscape
• Smaller building footprints and articulated facades break down the scale of the built environment and add visual interest
• Public spaces like plazas, pocket parks, and sidewalk cafes provide gathering places and support community interaction

Barriers to walkability

• Despite the benefits of walkable neighborhoods, many communities face significant barriers to pedestrian mobility
• These barriers can be physical, social, or institutional, and often disproportionately impact disadvantaged populations
• Identifying and addressing these barriers is crucial for creating more equitable and sustainable urban environments

Car-centric infrastructure

• Many cities are designed primarily for automobiles, with wide roads, high-speed traffic, and abundant parking
• This car-centric infrastructure creates hostile and unsafe conditions for pedestrians, discouraging walking
• Highways, arterials, and other high-volume roads can sever neighborhoods and limit pedestrian connectivity
• Retrofitting car-oriented suburbs for walkability can be challenging and costly, requiring significant changes to land use and transportation systems

Lack of pedestrian connectivity

• Disconnected or incomplete sidewalk networks force pedestrians to walk in the street or navigate unsafe routes
• Gated communities, superblocks, and other insular development patterns create barriers to pedestrian movement
• Lack of crosswalks, signals, and other pedestrian infrastructure can make crossing streets difficult and dangerous
• Poor connectivity disproportionately affects seniors, children, and people with disabilities who may have limited mobility options

Safety concerns and crime

• Real and perceived safety risks can deter people from walking, especially in high-crime or underserved areas
• Inadequate lighting, poor visibility, and lack of eyes on the street can create an environment that feels unsafe for pedestrians
• Fear of crime can lead to reduced pedestrian activity, which can further exacerbate safety issues
• Addressing safety concerns requires a combination of design interventions (lighting, surveillance) and community-based strategies (neighborhood watch, community policing)

Poorly maintained sidewalks and crosswalks

• Cracked, uneven, or obstructed sidewalks can create tripping hazards and accessibility barriers for pedestrians
• Inadequate snow removal, overgrown vegetation, and illegal dumping can make sidewalks impassable or unappealing
• Faded or missing crosswalk markings and pedestrian signals can make crossing streets confusing and unsafe
• Poorly maintained pedestrian infrastructure disproportionately impacts low-income and minority neighborhoods, exacerbating health and mobility inequities

Measuring and assessing walkability
