Drive Time Map: Understand 15, 30 and 60 Minute Reach
Learn how realistic drive-time boundaries differ from straight-line radius circles and route-based estimates.
Drive-time isochrones require an authorized routing service. The interactive map below shows geometric distance only. We never label circles as driving-time reach.

Learn how realistic drive-time boundaries differ from straight-line radius circles and route-based estimates.
What is Drive Time Map?
A drive-time polygon, also called a road-network isochrone, joins places reachable within a chosen time budget on a specific road graph. It is not a circle, and changes with travel mode and road data.
Learn how realistic drive-time boundaries differ from straight-line radius circles and route-based estimates. This guide explains the meaning of the output, the assumptions behind it, and situations where a more specialized dataset or routing service is necessary.
What is a drive-time map?
A drive-time polygon, also called a road-network isochrone, joins places reachable within a chosen time budget on a specific road graph. It is not a circle, and changes with travel mode and road data. Start by identifying the center, route, coordinate pair, polygon or reporting location required for the question. The input choice affects every number that follows.
How drive-time isochrones work
For a 30-minute map, the output must be computed by a connected routing/isochrone provider. Without that connection, the radius display on this site is only a straight-line planning reference, not verified driving reach. Set units explicitly and review the numerical output before using the visualization to plan an important decision.
Drive time map versus circle radius
Use the interactive workspace at the top of this page to explore the geometric reference, where available. A map layer alone cannot prove road accessibility, address membership, population counts or legal compliance.
What affects driving time?
Consider who will rely on the result and whether straight-line or network distance is appropriate. Document the selected assumptions before comparing locations or regions.

Retail, delivery and territory applications
For quick checking, compare the output with a known example or calculate a simple reference result independently. Distances measured from inconsistent center points are not comparable.
Routing-provider requirements and limitations
Different geocoders, map tiles, route providers, Census releases and geographic projections can disagree. Record provider, source year and your query inputs when results matter.

Frequently asked questions
How is drive time calculated?
Actual driving times depend on routes, speed limits, traffic, departure time and road restrictions. A simple circle cannot establish a verified driving-time boundary.
How accurate is Google Maps drive time?
Accuracy depends on inputs and methods: coordinate choice, geometry model and any external routing, postal or Census data. See the methodology and source-year notes; do not treat browser measurements as survey-grade.
Can you set a 1 mile radius on Google Maps?
Use the relevant map input, check the method and source limits, and confirm whether the question requires external route, population or third-party data.
How to make a drive time map?
Use the relevant map input, check the method and source limits, and confirm whether the question requires external route, population or third-party data.
How do I create my own custom map?
Use the relevant map input, check the method and source limits, and confirm whether the question requires external route, population or third-party data.
How far can I get in 3 hours?
Start with precise inputs, confirm the unit and method, and read the tool-specific limitations. See the methodology page for what results can and cannot establish.
How far can I drive in 30 minutes?
Actual driving times depend on routes, speed limits, traffic, departure time and road restrictions. A simple circle cannot establish a verified driving-time boundary.
Is 3 hours considered a road trip?
Use the relevant map input, check the method and source limits, and confirm whether the question requires external route, population or third-party data.
How long of a drive is 4 miles?
Use the relevant map input, check the method and source limits, and confirm whether the question requires external route, population or third-party data.
How many miles is $20 in gas?
Use the relevant map input, check the method and source limits, and confirm whether the question requires external route, population or third-party data.
How long is 1 mile at 30 mph?
Use the relevant map input, check the method and source limits, and confirm whether the question requires external route, population or third-party data.
Can you drive for 4 hours?
Use the relevant map input, check the method and source limits, and confirm whether the question requires external route, population or third-party data.
