从 Google 地图路线 API 响应中标记高速公路
Mark highway from Google Maps Directions API response
我目前正在 Android 上使用 google 地图方向 API 进行项目。
当我发出任何指示请求时，我会收到诸如 this one
之类的响应
我实际上能够解码该点以获得要到达的后续 LatLng 坐标列表。现在我需要了解两个后续 LatLng 点之间的每条路径是高速公路（您必须付费才能到达那里）还是普通街道。
我不认为这个回复有任何方法可以做到这一点。我可以使用任何其他参数来显示此信息吗？或者我可以使用其他 api 吗？

您可以在Directions Request中设置可选参数...&avoid=tolls...（或highways或两者：avoid=tolls|highways），例如：
https://maps.googleapis.com/maps/api/directions/json?origin=Toronto&destination=Montreal&avoid=tolls&mode=bicycling&key=[YOUR_KEY]
不用那种路也能得到响应。
更新
从this answer of Rishi Singh：对于收费公路，您可以在steps节点的html_instructions子节点中找到“toll”（或“toll road”）标签作为回应 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，您不仅要标记收费路段，还要标记整个 "step" 收费公路。
另外，看看 answer of Emad Dehnavi。
更新 2
也许可以为带有 "Partial toll road" 标签的步骤创建 "subrequest" 并获得更准确的响应 "Toll road" 部分...或将响应与 &avoid=tolls 组合并且没有那个限制并以这种方式获得通行费。
更新 3
还有另一种解决方法：您可以使用 Google 地图 Styled Map 并设置自定义样式（例如，红色代表有控制通道的道路，蓝色代表高速公路），如图所示：
然后在道路上获得分数并使用 答案中的方法来测试程式化地图上那个点的颜色，此外 JSON 分析，也许你确定 highway/toll 道路更准确地说。
我目前正在 Android 上使用 google 地图方向 API 进行项目。
当我发出任何指示请求时，我会收到诸如 this one
之类的响应我实际上能够解码该点以获得要到达的后续 LatLng 坐标列表。现在我需要了解两个后续 LatLng 点之间的每条路径是高速公路（您必须付费才能到达那里）还是普通街道。

您可以在Directions Request中设置可选参数...&avoid=tolls...（或highways或两者：avoid=tolls|highways），例如：
https://maps.googleapis.com/maps/api/directions/json?origin=Toronto&destination=Montreal&avoid=tolls&mode=bicycling&key=[YOUR_KEY]
不用那种路也能得到响应。
更新
从this answer of Rishi Singh：对于收费公路，您可以在steps节点的html_instructions子节点中找到“toll”（或“toll road”）标签作为回应 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，您不仅要标记收费路段，还要标记整个 "step" 收费公路。
另外，看看

也许可以为带有 "Partial toll road" 标签的步骤创建 "subrequest" 并获得更准确的响应 "Toll road" 部分...或将响应与 &avoid=tolls 组合并且没有那个限制并以这种方式获得通行费。
更新 3
还有另一种解决方法：您可以使用 Google 地图 Styled Map 并设置自定义样式（例如，红色代表有控制通道的道路，蓝色代表高速公路），如图所示：
然后在道路上获得分数并使用
