Compare if there is a point on a given route

Question

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

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

I need to return the amount of tolls and values of them in the interval Point A - Point B. 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.");
                }
            });
        }

Answer 1

Google Maps does not provide the option to see how many tolls there are on a route. Unlike various Google Maps conditions, you cannot enter within a code for it to calculate the amount of x locations on a specific route.

However, you can enter a condition for ALL the routes it calculates to avoid tolls. Just enter avoid=tolls (Toll, in English, is toll) on 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" async defer></script>

Remembering that Google will not prohibit showing roads by tolls, will only give priority to routes that have no tolls.

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