The invention discloses an intersection passing green wave guiding method, a vehicle-mounted unit and a computer readable storage medium. The vehicle-mounted unit receives a roadside data packet sent by a roadside unit near an intersection, extracts traffic light information from the roadside data packet, obtains lane data through a high-precision map, and according to the obtained lane data, screens out traffic light information influencing the current lane from the extracted traffic light information, determines a suggested speed per hour, displays the traffic light information on the high-precision map and draws the suggested speed per hour on a specific lane when a green wave passing guide triggering condition is reached, so that the intersection traffic light information can be presented and guided on a high-precision map, lane-level traffic light prompt and guidance can be accurately prompted, a driver is assisted in judging acceleration and deceleration of an intersection, the intersection traffic light waiting time is shortened, the commuting cost is reduced, and the intersection congestion condition is indirectly relieved.
本发明公开了一种路口通行绿波引导方法、车载单元和计算机可读存储介质,本发明中车载单元接收路口附近的路侧单元发送过来的路侧数据包,从中提取出红绿灯信息,并通过高精度地图获取车道数据,根据获取的车道数据,从提取出的红绿灯信息中筛选出影响当前车道的红绿灯信息,以及确定建议时速,当达到绿波通行引导触发条件时,在所述高精度地图上显示所述红绿灯信息以及在具体车道上绘制建议时速,如此,本发明可以实现路口红绿灯信息在高精度地图上的呈现以及引导,可精确提示车道级红绿灯提示与指引,协助驾驶员对路口加速减速的判断,减少路口红绿灯等待时间,减少通勤成本,间接的缓解路口拥堵情况。
