expect_arrival_time	预期的到达时间，UNIX时间戳。该字段将影响suggest_departure_time字段的返回，用于返回建议出发时间。取值范围：当前时间之后15分钟的任意时刻（小于这个时间则不做处理）若设置此参数，则路线规划服务将依据设定时间计算路线和耗时，并给出建议出发时间若算出的suggest_departure_time小于当前时间，则设置suggest_departure_time为-1。详细说明	string	选填	不填则不返回ext_duration字段注意：该功能为高级付费服务，需通过工单联系工作人员开通
gps_direction	起点的车头方向。字段类型：int64 取值范围：0-359	int	选填	车头方向为与正北方向顺时针夹角，该参数用于辅助判断起点所在正逆向车道，提高算路准确率。当speed大于1.5米/秒且gps_direction存在时，采用该方向。gps_direction并不代表需填写从gps获取的方向，可以填入校正后的方向。请填写尽量准确的方向，其准确性很大程度决定了计算的精度。
radius	起点的定位精度，字段类型：float，取值范围[0,2000]	float	选填	配合gps_direction字段使用
speed	起点车辆的行驶速度，字段类型：float	float	选填	单位：米/秒，配合gps_direction字段使用，当speed大于1.5米/秒且gps_direction存在时，采用gps_direction的方向。
output	表示输出类型，可设置为xml或json	string	选填	默认为json
sn	用户的权限签名，当AK设置为SN校验时，该参数必填 SN计算方法	string	选填
timestamp	时间戳，与SN配合使用	int64	SN存在时必填
callback	回调函数	string	选填	仅在output=json时，该参数有效
intelligent_plan	传入多个途经点，综合考虑路况、交规限行、途经点的相对位置以及路线整体的绕路成本等，支持智能调整途经点顺序，给出最优路线。可选值： 0（默认值）：不执行途经点智能规划 1：执行途经点智能规划。详细说明	int	选填	默认0：不执行途经点智能规划注意：该功能为高级付费服务，需通过工单联系工作人员开通
walkinfo	起终点步导路线	int	选填	1 表示下发起终点步导路线； 0 不下发起终点步导路线；默认值为0
steps_info	是否下发step详情 1：下发step详情 0：不下发step详情	int	选填
