Explore transport and travel times
Use Transit Map to explore routes and stops, compare data sources, measure distances and see how far you can walk or drive from a point.
- Find your area. Drag and zoom the map. On larger screens, use Search to find a place.
- Choose what to show. Select a Data layer in the left sidebar. Choose Map only for a background map without transport overlays.
- Inspect a feature. Click a route, stop or PTAL area to open its details in the right sidebar.
Start with an area and a data layer. The controls beside the left sidebar provide map and analysis tools. Use the sidebars
The left sidebar controls data layers and filters. The right sidebar shows the selected feature or completed travel-time calculation. Use the arrow on either sidebar to collapse or expand it and make room for the map.
The right sidebar's cross closes the current result. For a travel-time calculation, it also removes the colored areas and their origin marker. Collapsing the sidebar with its arrow keeps the result. 
Select a route to see its details on the right. The two sidebars can be collapsed independently.
Share the same view
Copy the page address from your browser. It saves the map position, zoom, background, data layer and filter settings. Confirmed walking or driving areas are saved too: opening the link restores their point, mode and travel time and calculates them again.
The screenshots below show the desktop layout. Available controls adapt to the screen size. Select an image to open it at full size.
Move, zoom and change the background
Drag to move around. Use the + and - buttons, your mouse wheel or a two-finger pinch to zoom. Open the map layer button beside the sidebar to choose a background such as Light, Dark, Gray or OpenStreetMap. 
The background selector changes the base map. The Data layer menu controls the transport overlay separately.
Find routes and nearby services
In layers that support route search, enter a route number or agency name under Find routes and select Show. Select a result to inspect it on the map.
To search around a place, set the radius in metres and select Show at center. On desktop, you can also right-click a point and choose Search routes in radius. Drag the search circle's center to move it, or its edge handle to change the radius. Use Reset map to leave the search results.
Measure distance
Select the ruler button beside the sidebar. Click successive points on the map to draw a measured path, then double-click to finish. Drag a point to adjust the path. Select the ruler button again to remove the measurement. 
The ruler measures the path you draw. It does not calculate a walking or driving route.
Build walking or driving areas
A travel-time area, also called an isochrone, shows places you can reach from a selected point using the road and path network.
1. Choose a mode and time. Open Choose travel time, the map-and-clock button. Select the walking or car row for the default 10, 20 and 30-minute areas. For a single area, enter a whole number from 5 to 30 minutes in that row and select its checkmark. 
Choose the walking or car icon for three areas, or enter a custom time and apply it.
2. Choose a point. Follow the message on the map and click your starting point. You can also select Use map center. 
The tool waits for your starting point before calculating.
3. Confirm the point. Select Confirm in the popup. To move the point first, click elsewhere on the map. Cancel dismisses that point so you can choose another. 
Confirm starts the calculation for this point, travel mode and time.
4. Read the result. The colored areas appear on the map, with an explanation and legend in the right sidebar. With the default times, the colors represent 0-10, 10-20 and 20-30 minutes. A custom time produces one area. 
Read each color against the legend. Use Map only when transport lines make the areas harder to see.
Changing the Data layer keeps your travel areas. The right sidebar's arrow hides or shows the explanation without removing them. Its cross removes the areas and origin marker. Driving estimates do not include live traffic.
Choose a data layer
- Map only
- Show the background map without transport data overlays. Walking and driving areas and the distance ruler remain available.
- Transit network
- Explore BusMaps routes and stops. Use the transport-mode and frequency filters to narrow what appears. Zoom in for more detail, then click a feature to inspect it.
- GTFS feeds
- Explore routes and stops by their source feed. Search the feed list by name or ID and select the feeds you want to display.
- WikiRoutes
- Explore the WikiRoutes network on its own.
- BusMaps + WikiRoutes
- Show the two networks together. Click a route to inspect its available details.
Select feeds in the left sidebar to narrow the displayed network to those sources. Read the transport filters
The mode colors identify routes such as buses, metro, trams and rail. Frequency categories distinguish Frequent, Regular, Local and Unknown services. Use the filters to show only the categories you need.
Accessible only includes agencies that explicitly supplied wheelchair accessibility information. Show stop-to-stop geometries displays connections between stops where no route alignment was supplied. Show problematic geometries includes route shapes flagged as potentially incorrect.
PTAL - Transport accessibility
PTAL describes access to public transport using walking time, service frequency and reliability. Select this layer and zoom in where data is available. Its legend runs from 1a to 6b; higher bands indicate better access.
Click an area to see its average PTAL score, Average Access Index and Access Index range in the right sidebar. These describe public transport access; they are separate from the walking and driving travel-time tool. 
The selected area is highlighted, and the right sidebar explains its accessibility metrics.
Frequently asked questions
- Why can I not see routes or stops?
- Check the Data layer first: Map only intentionally hides transport overlays. Otherwise, zoom in and review the mode, frequency and feed filters. Data availability varies by area.
- How do I reset the map?
- Reset filters restores the transport filter settings. Reset map leaves route-search results. To remove walking or driving areas, use the cross in their right-hand results sidebar.
- Why are there three travel-time colors?
- The default calculation shows separate 0-10, 10-20 and 20-30-minute bands. Enter a custom time between 5 and 30 minutes to show just one area.
- Why is a travel-time area unavailable?
- The selected point needs a reachable road or path in the calculation data. Try a nearby street or path. If the service is temporarily unavailable, retry the calculation.
- Does collapsing the right sidebar remove my areas?
- No. The arrow only collapses the sidebar. The cross removes the travel-time result. Switching data layers also keeps your calculated areas.
- Can I send someone the same calculation?
- Yes. Confirm and calculate your point, then copy the browser address. The link restores the same point, mode, time and map view.
- Does missing wheelchair information mean a service is inaccessible?
- No. Accessible only filters for explicitly supplied accessibility information; missing data does not prove a service is inaccessible.
- Can I use the transport data in an application?
- See API plans for application access, or connect an AI agent through MCP.
