Global Multi-Vehicle Decision Making System for Connected and Automated Vehicles in Dynamic Environment

Connected and automated vehicles (CAVs) have shown the potential to improve safety, increase road throughput, and optimize energy efficiency and emissions in several complicated traffic scenarios. This invention describes a mixed-integer programming (MIP) optimization method for global multi-vehicle decision making and motion planning of CAVs in a highly dynamic environment that consists of multiple human-driven, i.e., conventional or manual, vehicles and multiple conflict zones, such as merging points and intersections. The proposed approach ensures safety, high throughput and energy efficiency by solving a global multi-vehicle constrained optimization problem. The solution provides a feasible and optimal time schedule through road segments and conflict zones for the automated vehicles, by using information from the position, velocity, and destination of the manual vehicles, which cannot be directly controlled. Despite MIP having combinatorial complexity, the proposed formulation remains feasible for real-time implementation in the infrastructure, such as in mobile edge computers (MECs).

20180012493 · 2018-01-11 · ·

A method performed by a database managing system for maintaining a database comprising reported traffic-affecting events is provided. The system derives a position of a first vehicle supporting detection of vehicle surroundings and determines by comparing the vehicle position to positions of reported traffic-affecting events comprised in the database, that the first vehicle is approaching at least a first traffic-affecting event. The system prompts the first vehicle to attempt to detect the first traffic-affecting event, which prompting comprises providing to the first vehicle an expected position of the first traffic-affecting event. The system receives a response from the first vehicle, which response indicates whether or not the expected position was at least partly unobstructedly observable by the first vehicle. The response further indicates—if the expected position was at least partly unobstructedly observable—whether or not the first traffic-affecting event was at least partly detected by the first vehicle.

Mitigation of traffic oscillation on roadway

In an example, a method determines a first controllable vehicle traveling along a mitigation road segment of a roadway and determines a control lane in the mitigation road segment. The control lane includes the first controllable vehicle and is impedible by the first controllable vehicle. The method determines a first open lane in the mitigation road segment and applies a target mitigation speed to the first controllable vehicle in the control lane. The first open lane is adjacent to the control lane in the mitigation road segment and the target mitigation speed is based on a traffic state of the first open lane. The target mitigation speed adjusts a traffic stream that flows through the first open lane to mitigate traffic congestion located downstream of the mitigation road segment.
