Transit Analyst is an interactive tool for exploring transit accessibility to target resources from focus areas.
The marker shows the current location. The black points are those accesible from that point within the selected travel time, and the gray points are not accessible.
Click or tap on the "Info" tab to see detailed information for the current location
Choose a pointset to explore, and hover over or tap the points to see information for that location.
Move the mouse over the map to show blocks, and click or tap on a block to see detailed information for that block.
The "Show Travelshed" button will bring up a travelshed centered on the marker. Each band of color represents an area that can be traveled to on public transit, in 15 minute increments.
