I have a page that calculates the distance between Point A and Point B , but I need to compute tolls on this route.

I think of having a bank with the toll (lat and lng) coordinates and check if it exists on the route, but I do not know how.

I need to return the number of tolls and their values in the Point A - Point B range. Any help will be valid.

JavaScript:

var options = {
			componentRestrictions: {country: 'br'}
		};	
        var source, destination;
        var directionsDisplay;
        var directionsService = new google.maps.DirectionsService();
        google.maps.event.addDomListener(window, 'load', function () {
            new google.maps.places.Autocomplete(document.getElementById('txtSource'), options);
            new google.maps.places.Autocomplete(document.getElementById('txtDestination'), options);
            directionsDisplay = new google.maps.DirectionsRenderer({ 'draggable': true });
        });
		
		    var mumbai = new google.maps.LatLng(-19.9166813, -43.9344931);
            var mapOptions = {
                zoom: 5,
                center: mumbai
            };
			
            map = new google.maps.Map(document.getElementById('dvMap'), mapOptions);


        function GetRoute() {
            directionsDisplay.setMap(map);
            //directionsDisplay.setPanel(document.getElementById('dvPanel'));

            //*********DIRECOES E ROTAS**********************//
            source = document.getElementById("txtSource").value;
            destination = document.getElementById("txtDestination").value;
			
			
            var request = {
                origin: source,
                destination: destination,
                travelMode: google.maps.TravelMode.DRIVING
            };
            directionsService.route(request, function (response, status) {
                if (status == google.maps.DirectionsStatus.OK) {
                    directionsDisplay.setDirections(response);
                }
            });

            //*********DISTANCIA E DURACAO**********************//
            var service = new google.maps.DistanceMatrixService();
            service.getDistanceMatrix({
                origins: [source],
                destinations: [destination],
                travelMode: google.maps.TravelMode.DRIVING,
                unitSystem: google.maps.UnitSystem.METRIC,
                avoidHighways: false,
                avoidTolls: false
            }, 
			
			function (response, status) {
                if (status == google.maps.DistanceMatrixStatus.OK && response.rows[0].elements[0].status != "ZERO_RESULTS") {
                    var distance = response.rows[0].elements[0].distance.text;
                    var duration = response.rows[0].elements[0].duration.text;
                    var dvDistance = document.getElementById("dvDistance");
                    dvDistance.innerHTML = "";
                    dvDistance.innerHTML += "Distancia: " + distance + "<br />";
                    dvDistance.innerHTML += "Duração:" + duration + "<br />";

                } else {
                    alert("Não foi possível traçar essa rota.");
                }
            });
        }

Google Maps does not provide the option to see how many tolls a route has. Unlike many Google Maps conditions, you can not tell a code within a code to calculate the amount of x locations on a specific route.

However, you can enter a condition so ALL routes it calculates avoid tolls. Simply enter avoid=tolls (Toll) in the API call link. In this case, the link will look like this:

<script src="https://maps.googleapis.com/maps/api/js?key=YOUR_KEY&libraries=places,geometry&avoid=tolls"asyncdefer></script>

RememberingthatGooglewillnotbebannedfromshowingtollroads,itwillonlygiveprioritytotoll-freeroutes.

Ah, by increasing the response, Google allows you to avoid as well as tolls, freeways and ferries. In this case, just put one or all of the items here: avoid=tolls|highways|ferries
