从Google Maps Directions API响应Mark高速公路
问题描述 投票：3回答：1
我目前正在使用Android上的谷歌地图Directions API进行项目。
当我提出任何指示请求时，我会得到this one等回复
我实际上能够解码点以获得要达到的后续LatLng坐标的列表。现在我需要了解两个后续LatLng点之间的每条路径，如果它是一条公路街道（你必须付钱才能到达那里）或正常的街道。
我认为从这种反应中没有办法做到这一点。我可以使用任何其他参数来显示此信息吗？或者是否还有其他api我可以使用？

您可以在...&avoid=tolls...中设置可选参数highways（或avoid=tolls|highways或两者：Directions Request），例如：
https://maps.googleapis.com/maps/api/directions/json?origin=Toronto&destination=Montreal&avoid=tolls&mode=bicycling&key=[YOUR_KEY]
没有那种道路就能得到回应。
UPDATE
来自this Rishi Singh的回答：对于收费公路，您可以在toll节点的toll road子节点中找到“html_instructions”（或“steps”）标签以响应JSON，如：
...
"steps": [
{
"distance": {
"text": "42.5 mi",
"value": 68323
},
"duration": {
"text": "38 mins",
"value": 2254
},
"end_location": {
"lat": 42.4352772,
"lng": -87.95487469999999
},
"html_instructions": "Merge onto <b>I-94 E</b><div style=\"font-size:0.9em\">Partial toll road</div><div style=\"font-size:0.9em\">Entering Illinois</div>",
"maneuver": "merge",
"polyline": {
...
因此，您不仅标记收费部分，而且标记收费公路的整个“步骤”。
另外，看看this的Emad Dehnavi答案。
更新2
也许可以通过“部分收费公路”标签创建“子请求”，并通过完全“收费公路”部分获得更精确的响应...或者将响应与&avoid=tolls结合并且没有这种限制并以这种方式获得收费部分。
更新3
还有一个解决方法：您可以使用Google Maps Styled Map并设置自定义样式（例如，红色用于带有受控访问的道路和蓝色用于高速公路）类似于图片：
然后获得道路上的积分并使用像this那样的方法，除了JSON分析之外，在那个时候在程式化地图上测试颜色，可能更准确地确定高速公路/收费公路。
