Abstract

The invention discloses a traffic assessment method for a bus and autonomous vehicle mixed lane. The method comprises the steps: depicting a bus based on the time when the bus arrives at each road section; according to the driving time and period of the bus, calculating the local coordinates and phase differences of all road sections, wherein the road sections comprise a common road section, an entrance road section, an exit road section, an overtaking road section and a non-overtaking road section; based on the starting point and the destination point of the automatic driving vehicle, distributing the space-time tracks for the automatic driving vehicle on each road section; calculating the passing time of the automatic driving vehicle on different road sections; and calculating the passing time of all the automatic driving vehicles on each road section in one period. According to the invention, the advantages of the road resources of the bus lane and the automatic driving technology are fully utilized, so that the traffic efficiency and safety of the automatic driving vehicle are improved while the public traffic service level is guaranteed. The invention further provides an effective traffic evaluation method for the traffic efficiency of the mixed traffic lane.

Description

technical field [0001] The invention relates to the field of automatic driving technology and urban public transportation, in particular to a traffic evaluation method and system for a mixed lane of public transportation and automatic driving vehicles. Background technique [0002] Autonomous driving technology has developed very rapidly in recent years, because it can automatically drive vehicles and accurately detect road conditions, and has great potential in improving road traffic capacity, reducing energy consumption and pollution emissions. However, despite considerable progress in autonomous driving technology, full-fledged, fully autonomous driving is not yet possible at this stage. At the same time, manual driving vehicles will also exist for a long time, forming a "automatic driving-manual driving mixed traffic" traffic scene. For self-driving vehicles, the existence of manually-driven vehicles will seriously affect the efficiency of traffic, and increase the diff...
