A traffic flow congestion incident associated with a segment of roadway that is proximate to a responder vehicle can be established. The congestion can include a set of automobiles on the roadway. The automobiles can include a driver operated vehicle, a semi-autonomous vehicle, and an autonomous vehicle. The responder vehicle can be an emergency response vehicle associated with an emergency service or emergency entity. A notification can be conveyed to a computing device associated with the automobiles responsive to the establishing. The notification can alert the operator of the automobile that the responder vehicle is proximate.

Techniques for creating, configuring, and employing flow management lights are presented. Such light(s) can comprise or be associated with a flow management component (FMC) that can employ sensors to monitor environmental conditions in a defined area of people or vehicle traffic, and can enhance its function to manage flow and security of the people or vehicle traffic. Such light(s) can be installed in a defined area. FMC can monitor and determine a context associated with the defined area, and can adjust light output or another parameter(s) of one or more lights based on the determined context. Over time, FMC can learn contexts of people or vehicle traffic at various times and adjust operations accordingly for the particular context at a specific time. FMC can control operations of such light(s) in relation to enhancing security and safety of people or traffic, business and sales operations, and other objectives.

The disclosure provides a method for acquiring a traffic volume and an electronic device. The method includes: acquiring first feature information and signal timing information of each of the phases in a target road section; and acquiring a traffic volume of the whole road section in a current signal light control period of the target road section based on the first feature information and the signal timing information.

A signal passing support apparatus includes: a providing device provides support information for supporting a vehicle to pass through a traffic signal to a driver, and a determining device that determines whether or not a vehicle speed is larger than a first reference speed and is smaller than a second reference speed, the providing device starts the providing of the support information when it is determined that the vehicle speed is larger than the first reference speed when the providing device does not provide the support information, and the providing device terminates the providing of the support information when the vehicle speed is smaller than the second reference speed when the providing device provides the support information.

A method for controlling a variable lane includes: acquiring first traffic data for a first driving direction corresponding to the variable lane and second traffic data for a second driving direction of a lane adjacent to the variable lane; determining a first saturation in the first driving direction based on the first traffic data and determining a second saturation in the second driving direction based on the second traffic data; determining an imbalance coefficient between the first driving direction and the second driving direction based on the first saturation and the second saturation; and controlling a driving direction of the variable lane based on the imbalance coefficient. An apparatus for controlling a variable lane and a non-transitory computer-readable storage medium are also provided.

The disclosure includes a system and method for managing traffic in a roadway system based on Basic Safety Message data (“BSM data”) included in a set of Basic Safety Messages (“BSMs”). The method may include wirelessly receiving a set of BSMs describing a set of vehicles traveling along the roadway system. Each BSM included in the set of BSMs may describe a specific vehicle included in the set of vehicles, including that vehicle's lane, speed and heading of travel. The method may include analyzing the BSM data to determine whether there is an imbalance of traffic flow among a first set of vehicles traveling towards a first heading and a second set of vehicles traveling towards a second heading. The method may include determining that the bidirectional lane will be reconfigured so that traffic in the bidirectional lane flows towards the second heading based on the imbalance of traffic flow.
