Question

在相同的到达/离开时间，为什么从 A 到 B 的 trafficTime（最快）比从 A 到 B 通过 C 的 trafficTime 长？

V7 请求：A 到 B：trafficTime = 4979 秒 https://route.ls.hereapi.com/routing/7.2/calculateroute.json?apiKey=KEY&waypoint0=32.6289624435649%2C35.079885159610136&waypoint1=32.0155%2C34.7505&mode=fastest%3Bcar&combineChange =true&language=he&instructionformat=text&departure=2020-05-21T10:00:00.000Z

A 到 B 通过 C：trafficTime = 4936 秒 https://route.ls.hereapi.com/routing/7.2/calculateroute.json?apiKey=KEY&waypoint0=32.6289624435649%2C35.079885159610136&waypoint1=32.119485%2C34.938341&waypoint234=32.0155%2 7505&mode=fastest%3Bcar&combineChange=true&language=he&instructionformat=text&departure=2020-05-21T10:00:00.000Z

V8 也是 A 到 B：持续时间 = 3987 秒 https://router.hereapi.com/v8/routes?transportMode=car&return=travelSummary,summary,polyline,actions&origin=32.6289624435649,35.079885159610136&destination=32.0155,34.7505&apikey=KEY

A 到 B 通过 C：持续时间 = 3955 秒 https://router.hereapi.com/v8/routes?transportMode=car&return=travelSummary,summary,polyline,actions&origin=32.6289624435649,35.079885159610136&destination=32.0155,34.7505&via=32.11914853 ,. stopDuration=0&apikey=KEY

如果我要求显示几个替代方案（仅在没有“到达”参数的情况下可用）我会得到更快和更短的路线：V7 A 到 B 有替代方案：最快的 trafficTime = 4765 https://route.ls.hereapi.com/routing/7.2 /calculateroute.json?apiKey=KEY&waypoint0=32.6289624435649%2C35.079885159610136&waypoint1=32.0155%2C34.7505&mode=fastest%3Bcar&combineChange=true&language=he&instructionformat=text&departure=2020-05-200T10:00:00salternative=90&

在我们最后创建相同的场景，清楚地表明当我们指定 API 中给出的中间航点时，它们会发生重大的路线变化，这会减少旅行时间。请检查附件
