Distance/Time: road-travel areas

Travel areas follow the road network, so their shapes differ from straight-line circles. Use them to explore a service area or compare travel bands from a starting postcode.

Travel areas on the map. Isochrones are travel-area shapes. Their irregular edges show why a time-based catchment can look very different from a circle: the available network affects how far you can travel. This is an illustrative display made with the tool’s renderer, not a calculated route or journey-time estimate. Use Create areas with your own starting location and settings to calculate your map.

Current panel with an example travel result. The picture illustrates the controls, not a real journey calculation.
  1. Starting postcode

    Enter the full postcode of the starting location. It is the origin for every band in this calculation. Check the spelling before making the request.

  2. Measure by Distance or Time

    Choose Distance for miles travelled or Time for minutes. The number field changes its meaning with this choice. A 20-minute area is not the same as a 20-mile area or a 20-mile radial circle.

  3. Distance / Time limit

    Enter the outer travel limit you want to explore. Travel areas are calculated estimates from the routing service and road network, not a promise that every journey will take exactly that time.

  4. Travel bands

    Choose 1, 2, 3, 4, 5 or 10 equal bands within the total. For example, a 30-minute limit with three bands represents 10, 20 and 30 minutes. More bands show detail but add visual complexity.

  5. Create areas

    Sends the calculation and replaces the previous travel areas with the result. Wait for it to finish before clicking again. The online routing service is required. In the locked/sample tool, the calculation uses sample settings (20 miles and three bands) and displays an unlock message; it does not honour every requested value.

  6. Colour key

    Each band has a colour control. Choose a progression that lets readers distinguish nearer and farther bands. Change the origin, measure or limits and calculate again if you need different geography; recolouring alone does not recalculate it.

  7. Show areas and show legend

    When travel results are present, the visibility controls let you hide the shapes or their legend separately. The areas remain available until deleted or replaced. This is useful when comparing them with your territory assignments.

  8. Move, resize or reset the travel legend

    Drag the travel legend background to move it. Scrolling over it changes its size independently of the map, with down making it smaller and up larger. Use Reset position to bring it back if it is off the page or awkwardly sized.

  9. Delete areas

    Removes the calculated travel areas. It is different from hiding them. Save a copy if the previous calculation is an important comparison you may want later.
