Salve e categorize o conteúdo com base nas suas preferências.
Essas camadas modificam a camada do mapa de base para mostrar as condições atuais de trânsito, redes locais de transporte público ou informações sobre trajetos de bicicleta.
Elas estão disponíveis em algumas regiões.
Camada de trânsito
Com a API Maps JavaScript, você pode adicionar informações de trânsito em tempo real (quando compatível) aos seus mapas usando o objeto TrafficLayer. Essas informações são atualizadas com frequência, mas não instantaneamente. É pouco provável que solicitações consecutivas para a mesma área produzam resultados diferentes.
Com a API Maps JavaScript, você pode mostrar a rede de transporte público de uma cidade no seu mapa usando o objeto TransitLayer. Quando a camada de transporte público é ativada e o mapa está centralizado em uma cidade que oferece informações desse tipo, o mapa mostra as principais linhas como traços grossos e coloridos. A cor do traço é definida com base nas informações do operador da linha de transporte público. Ativar essa camada muda o estilo do Mapa de base para destacar melhor os trajetos de transporte público.
Com a API Maps JavaScript, é possível adicionar informações de bicicleta aos mapas usando o objeto BicyclingLayer. O objeto BicyclingLayer renderiza, sobre o mapa especificado, uma camada de caminhos de bicicleta, sugestões de trajetos e outras sobreposições específicas para o uso desse meio de transporte. A camada também altera o estilo do mapa básico para destacar as ruas que permitem trajetos de bicicleta e esmaecer as ruas inapropriadas para isso.
O exemplo abaixo mostra a camada de bicicleta ativada em um mapa de Cambridge, MA, EUA:
Os trajetos para bicicletas são mostrados em verde escuro. As ruas com ciclovias dedicadas são indicadas em verde claro, e os tracejados indicam ruas ou caminhos recomendados para ciclistas.

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.
