HERE Api Maps计算的路线不遵循陆路

Question

我正在使用此REST调用从HERE Maps Routing API获取路线信息：

"https://route.api.here.com/routing/7.2/calculateroute.json?" +
         "waypoint0=34.045535,-118.222708&waypoint1=34.045142,-118.235551" +
         "&mode=fastest;car;traffic:disabled&departure=now&app_id=[appID]&app_code=[appCode]"

该呼叫有效，这是响应：

这是有效的，只是它似乎不包括该路线的所有链接点。最终路线的屏幕截图非常不言自明：

API返回的链接点标出了红线，而不是绿线，后者应该是实际的陆上路线。

我是否缺少任何可能导致此问题的属性？

Answer 1

[请尝试考虑使用流量模式：已启用

具有禁用模式：没有提供出发时间：

基于静态时间的限制：已忽略实时流量关闭：已忽略。实时交通流速度：被忽略。历史流量和预测流量：已忽略

提供出发时间：

基于静态时间的限制：如果在限制的有效期内穿越道路，则可以避免。实时交通封闭：在整个路线上均有效。实时交通流速度：被忽略。历史流量和预测流量：已忽略

注：禁用和启用流量之间的差异仅影响路由的计算。仍将使用与traffic：enabled相同的规则为所有路由计算该路由的通过时间。

也请参考下面的汽车路线示例：https://developer.here.com/documentation/examples/rest/routing
