A roadway condition monitoring system is configured to receive sensed data that is acquired by sensors that are mounted on vehicles that operate on a roadway. The sensed data includes values of parameters that characterize a roadway condition, including a pattern of travel of the vehicles along the roadway or a mapping of the roadway. A current roadway condition is calculated from the sensed data that is received during a current trip of the vehicles on a segment of the roadway, and the current roadway condition is compared with a nominal roadway condition. The calculation of the nominal roadway condition utilizes the sensed data that is received from the sensors during a plurality of trips of the vehicles on the segment. When an anomaly is detected in which the current roadway condition deviates from the nominal roadway condition, a notification of the detected anomaly is issued.

A predictive driver intention to stop (DITS) system for a vehicle having an engine includes one or more sensors configured to measure a set of operating parameters of the vehicle including at least (i) vehicle speed and (ii) vehicle deceleration rate. A controller is configured to identify no-stop braking events and complete stop braking events, and reference a generated baseline probability table indicating a probability of a driver braking to bring the vehicle to a stop, based on at least the vehicle speed and vehicle deceleration rate measured during at least one of the identified no-stop braking events and complete stop braking events. The controller is further configured to predict a DITS event based on the generated baseline probability table, and control operation of the engine based on the predicted DITS event to facilitate reducing vehicle fuel consumption and/or tailpipe emissions.

Traffic control systems, signal control systems, and methods of using such systems are disclosed. A real-time adaptive traffic control system includes multiple signal control systems, each associated with a signalized intersection. Each signal control system includes a receiver, a processor, and a transmitter. The receiver receives inflow traffic control information from other signal control systems and information associated with one or more vehicles or devices. The processor generates a signal timing plan based on the information and the inflow traffic control information. The transmitter transmits outflow traffic control information to other signal control systems. A fee or toll may be incurred for receiving the route information associated with a vehicle or device. The result of providing such route information may be better traffic flow for the transmitting vehicle or device and other vehicles or devices resulting from improved information being available to the traffic control system.

A method is provided for controlling a passage along a single-track roadway section, wherein confrontational meetings of vehicles moving in opposite directions of travel are avoided through speed adjustment and use of stopping facilities within the single-track roadway section. A system and a vehicle for carrying out the method are further provided.
