How to get total driving distance with Google Maps API V3?

60.2k Views Asked by mpen At 17 May 2025 at 07:55

I used to be able to get it like this:

directionsService.route(directionsRequest, function(directionsResult, directionsStatus) {
    var directionsRenderer = new google.maps.DirectionsRenderer({
        directions: directionsResult,
        map: map
    });
    $('#distance').text(directionsResult.trips[0].routes[0].distance.text)
    $('#duration').text(directionsResult.trips[0].routes[0].duration.text)
})

But it looks like they changed their API on me! Looks like trips is no longer there, and routes only gives you a bunch of legs... do I really have to iterate over all the legs and sum up the distance now?

Mark's answer is in meters for totalDistance and seconds for totalDuration.

If you're in the U.S. and want miles with a single decimal point, multiply like so:

var METERS_TO_MILES = 0.000621371192;
$('#distance').text((Math.round( totalDistance * METERS_TO_MILES * 10 ) / 10)+' miles');

And if you want minutes:

$('#distance').text(Math.round( totalDuration / 60 )+' minutes');

Take a look here:

The Directions Results Object

It looks like you now have to sum up each leg distance.

legs[] contains an array of DirectionsLeg objects, each of which contains information about a leg of the route, from two locations within the given route. A separate leg will be present for each waypoint or destination specified. (A route with no waypoints will contain exactly one DirectionsLeg.) Each leg consists of a series of DirectionSteps.

you can easily get by using :

Distance by using:

directionsDisplay.directions.routes[0].legs[0].distance.text

Duration by using:

directionsDisplay.directions.routes[0].legs[0].duration.text

As per Leniel's answer:

var totalDistance = 0;
var totalDuration = 0;
var legs = directionsResult.routes[0].legs;
for(var i=0; i<legs.length; ++i) {
    totalDistance += legs[i].distance.value;
    totalDuration += legs[i].duration.value;
}
$('#distance').text(totalDistance);
$('#duration').text(totalDuration);

Actually, this works just fine too, if you don't have any waypoints:

$('#distance').text(directionsResult.routes[0].legs[0].distance.text);
$('#duration').text(directionsResult.routes[0].legs[0].duration.text);

Here's a fuller example using lodash. Shouldn't be too hard to replace flatBy and sum if you're not using it.

/**
 * Computes the total driving distance between addresses. Result in meters.
 *
 * @param {string[]} addresses Array of address strings. Requires two or more.
 * @returns {Promise} Driving distance in meters
 */
export default function calculateDistance(addresses) {
    return new Promise((resolve, reject) => {
        if(addresses.length < 2) {
            return reject(new Error(`Distance calculation requires at least 2 stops, got ${addresses.length}`));
        }

        const {TravelMode, DirectionsService, DirectionsStatus} = google.maps;

        const directionsService = new DirectionsService;
        const origin = addresses.shift();
        const destination = addresses.pop();
        const waypoints = addresses.map(stop => ({location: stop}));

        directionsService.route({
            origin,
            waypoints,
            destination,
            travelMode: TravelMode.DRIVING,
        }, (response, status) => {
            if(status === DirectionsStatus.OK) {
                let distances = _.flatMap(response.routes, route => _.flatMap(route.legs, leg => leg.distance.value));

                return resolve(_.sum(distances));
            } else {
                return reject(new Error(status));
            }
        });
    });
}

Remember to include the Google Maps API:

<script src="https://maps.googleapis.com/maps/api/js?key=API_KEY&libraries=places"></script>

Also, I'm pretty sure their ToS require you to display a Google Map too.
