SJ-BE iMap

The San José Bike Equity Web Map (SJ-BE iMap)

The San José Bike Equity Web Map (SJ-BE iMap) measures and maps the City of San José's best and worst regions for cycling through geospatial analyses and visualization

Alignment Score

SPUR-SAVI

San Jose 15-Minute City

As part of SPUR's 15-minute city projects, SAVI measured and mapped access and proximity (within one-half mile) to groceries, financial institutions, parks, community centers, childcare, and health facilities. They show that areas with high access to some services and amenities, say, financial institutions, can have low access to other services and amenities, in particular, groceries.
