Warstwy Ruch, Transport publiczny i Rower modyfikują warstwę mapy podstawowej, aby wyświetlać aktualne warunki na drogach, informacje o lokalnych sieciach transportu publicznego lub informacje o trasach rowerowych.
Te warstwy są dostępne w wybranych regionach.
Warstwa ruchu
Interfejs Maps JavaScript API umożliwia dodawanie informacji o natężeniu ruchu w czasie rzeczywistym (tam, gdzie jest to obsługiwane) do map za pomocą obiektu TrafficLayer. Informacje o ruchu są często odświeżane, ale nie natychmiast. Szybkie wysyłanie kolejnych próśb dotyczących tego samego obszaru prawdopodobnie nie przyniesie różnych wyników.
Interfejs Maps JavaScript API umożliwia wyświetlanie na mapie sieci transportu publicznego miasta za pomocą obiektu TransitLayer. Gdy warstwa transportu publicznego jest włączona, a mapa jest wyśrodkowana na mieście, które obsługuje informacje o transporcie publicznym, na mapie będą widoczne główne linie transportu publicznego w postaci grubych, kolorowych linii. Kolor linii jest ustawiany na podstawie informacji od operatora linii transportowej. Włączenie warstwy transportu publicznego spowoduje zmianę stylu mapy podstawowej w celu lepszego wyróżnienia tras transportu publicznego.
Jeśli jesteś instytucją publiczną nadzorującą transport publiczny w Twoim mieście i chcesz, aby Twoje dane były uwzględniane, odwiedź stronę Programu partnerskiego Google ds. transportu publicznego, aby dowiedzieć się więcej.
Na przykładzie poniżej widać włączoną warstwę Transport publiczny na mapie Londynu w Wielkiej Brytanii:
Interfejs Maps JavaScript API umożliwia dodawanie informacji o rowerach do map za pomocą obiektu BicyclingLayer. BicyclingLayer renderuje warstwę ścieżek rowerowych, sugerowanych tras rowerowych i innych nakładek związanych z rowerami na danej mapie. Dodatkowo warstwa zmienia styl mapy podstawowej, aby wyróżnić ulice z trasami rowerowymi i pomniejszyć ulice nieodpowiednie dla rowerów.
Ten przykład pokazuje włączony na mapie Cambridge w Massachusetts (Stany Zjednoczone) widok Trasy rowerowe:
Ciemnozielone trasy to ścieżki rowerowe. Jasnozielone trasy wskazują ulice z wydzielonymi pasami rowerowymi. Przerywana linia wskazuje ulice lub ścieżki zalecane do jazdy na rowerze.

When the Transit Layer is enabled, and the map is centered on a city\nthat supports transit information, the map will display major transit lines as\nthick, colored lines. The color of the line is set based upon information from\nthe transit line operator. Enabling the Transit Layer will alter the style of\nthe base map to better emphasize transit routes.\n\nIf you're a public agency that oversees public transportation for your city and\nwould like your data to be included, please visit\nthe [Google Transit Partner\nProgram](https://maps.google.com/help/maps/mapcontent/transit/) site to learn more.\n\nThe following example shows the Transit layer enabled on a map of London, UK: \n\n### TypeScript\n\n```typescript\nfunction initMap(): void {\n const map = new google.maps.Map(\n document.getElementById(\"map\") as HTMLElement,\n {\n zoom: 13,\n center: { lat: 51.501904, lng: -0.115871 },\n }\n );\n\n const transitLayer = new google.maps.TransitLayer();\n\n transitLayer.setMap(map);\n}\n\ndeclare global {\n interface Window {\n initMap: () =\u003e void;\n }\n}\nwindow.initMap = initMap;https://github.com/googlemaps/js-samples/blob/2683f7366fb27829401945d2a7e27d77ed2df8e5/samples/layer-transit/index.ts#L8-L27\n```\n| **Note:** Read the [guide](/maps/documentation/javascript/using-typescript) on using TypeScript and Google Maps.\n\n### JavaScript\n\n```javascript\nfunction initMap() {\n const map = new google.maps.Map(document.getElementById(\"map\"), {\n zoom: 13,\n center: { lat: 51.501904, lng: -0.115871 },\n });\n const transitLayer = new google.maps.TransitLayer();\n\n transitLayer.setMap(map);\n}\n\nwindow.initMap = initMap;https://github.com/googlemaps/js-samples/blob/2683f7366fb27829401945d2a7e27d77ed2df8e5/dist/samples/layer-transit/docs/index.js#L7-L17\n```\n| **Note:** The JavaScript is compiled from the TypeScript snippet.\n[View example](/maps/documentation/javascript/examples/layer-transit)\n\n### Try Sample\n\n[JSFiddle.net](https://jsfiddle.net/gh/get/library/pure/googlemaps/js-samples/tree/master/dist/samples/layer-transit/jsfiddle) [Google Cloud Shell](https://ssh.cloud.google.com/cloudshell/editor?cloudshell_git_repo=https%3A%2F%2Fgithub.com%2Fgooglemaps%2Fjs-samples&cloudshell_git_branch=sample-layer-transit&cloudshell_tutorial=cloud_shell_instructions.md&cloudshell_workspace=.)\n\nBicycling Layer\n---------------\n\nThe Maps JavaScript API allows you to add bicycle information to your maps using\nthe `BicyclingLayer` object. The `BicyclingLayer` renders a layer of bike\npaths, suggested bike routes and other overlays specific to bicycling usage on\ntop of the given map. Additionally, the layer alters the style of the base map\nitself to emphasize streets supporting bicycle routes and de-emphasize streets\ninappropriate for bicycles.\n\nThe following example shows the Bicycle layer enabled on a map of\nCambridge, MA: \n\n### TypeScript\n\n```typescript\nfunction initMap(): void {\n const map = new google.maps.Map(\n document.getElementById(\"map\") as HTMLElement,\n {\n zoom: 14,\n center: { lat: 42.3726399, lng: -71.1096528 },\n }\n );\n\n const bikeLayer = new google.maps.BicyclingLayer();\n\n bikeLayer.setMap(map);\n}\n\ndeclare global {\n interface Window {\n initMap: () =\u003e void;\n }\n}\nwindow.initMap = initMap;https://github.com/googlemaps/js-samples/blob/2683f7366fb27829401945d2a7e27d77ed2df8e5/samples/layer-bicycling/index.ts#L8-L27\n```\n| **Note:** Read the [guide](/maps/documentation/javascript/using-typescript) on using TypeScript and Google Maps.\n\n### JavaScript\n\n```javascript\nfunction initMap() {\n const map = new google.maps.Map(document.getElementById(\"map\"), {\n zoom: 14,\n center: { lat: 42.3726399, lng: -71.1096528 },\n });\n const bikeLayer = new google.maps.BicyclingLayer();\n\n bikeLayer.setMap(map);\n}\n\nwindow.initMap = initMap;https://github.com/googlemaps/js-samples/blob/2683f7366fb27829401945d2a7e27d77ed2df8e5/dist/samples/layer-bicycling/docs/index.js#L7-L17\n```\n| **Note:** The JavaScript is compiled from the TypeScript snippet.\n[View example](/maps/documentation/javascript/examples/layer-bicycling)\n\n### Try Sample\n\n[JSFiddle.net](https://jsfiddle.net/gh/get/library/pure/googlemaps/js-samples/tree/master/dist/samples/layer-bicycling/jsfiddle) [Google Cloud Shell](https://ssh.cloud.google.com/cloudshell/editor?cloudshell_git_repo=https%3A%2F%2Fgithub.com%2Fgooglemaps%2Fjs-samples&cloudshell_git_branch=sample-layer-bicycling&cloudshell_tutorial=cloud_shell_instructions.md&cloudshell_workspace=.)\n\nDark green routes indicated dedicated bicycle routes.
