The optical unit includes a magnifying optical unit attached to the housing and reflecting the light toward the windshield, a screen attached to the housing and reflecting or transmitting the light toward the magnifying optical unit, and an incident angle changing unit changing an incident angle of the light that goes incident on the screen.

Abstract: A self-learning cycle timer is disclosed. A wait time is measured between a first indication, associated with a stop, and a second indication, associated with movement following the stop, each indication received from a smart device. A geolocation is received from the smart device and a traffic signal identified at the geolocation. The traffic signal's area of influence is determined. The wait time is determined to have occurred inside the area of influence. An average cycle time and a reference time associated with the traffic signal are retrieved from a database. A cycle time associated with the traffic signal is calculated according to the wait time and the reference time. The average cycle time is updated according to the calculated cycle time.

Abstract: An adjustable head-up display (HUD) arrangement for a vehicle is provided that may be, for example, suitable for tuning a perceived distance to projected information based on a current speed and application type of the vehicle. A corresponding method for operating the HUD and to a related computer program product are also provided.

Abstract: A system for controlling activation of a traffic warning sign. The system receives a signal generated from a local sensor indicating presence of an automobile and sends an activate signal command in response. The system will activate a local interface logic controller in response to receiving the activate signal command. The system further generates a Wi-Fi connect request with an SSID in response to activating the interface logic controller. The system sends the Wi-Fi connect request to a remote system. The system further determines if the traffic warning sign should be activated and if a positive determination is made, activate the traffic warning sign. Determination is made by determining if a Wi-Fi remote connect request is received. If it is determined a remote connect request has been received, a traffic warning message is generated and sent to a terminal for display or activation.

Abstract: A computer-readable detailed map format is disclosed. The map format can be used in the operation of an autonomous vehicle. The detailed map format includes a plurality of lane segments and a plurality of lane links. Each of the lane links can extend between two lane segments across a traffic intersection. Each of the lane links can also be associated with one of a plurality of traffic signals. A transition rule is associated with a first lane link and based on information associated with the one of the plurality of traffic signals associated with the first lane link. An interlock rule can be based on information associated with the one of the plurality of traffic signals associated with a second lane link. The first lane link and second lane link can be associated with different traffic signals and can extend between different lane segments across the traffic intersection.

Abstract: An illumination apparatus which comprises a timing module, a control module and a first power conversion module and can be automatically adjusted with time is provided. The timing module sets the time into N sessions, and generates an ith timing signal according to the ith session corresponding to the current time, wherein i and N are natural numbers and i?N. The control module reads the ith timing signal from the timing module, and outputs an ith control signal. The first power conversion module, coupled to an AC power supply, the control module and a first light source, converts the AC power supply signal into a DC power signal and outputs the DC power signal to the control module, and outputs an ith DC driving signal to drive the first light source to emit light of the ith situation after receiving the ith control signal.

Abstract: A traffic management system and method are provided that determine and present a target speed for a vehicle to travel from a first position to a second position when a signaling device at the second position is in a desired phase. The target average speed can be presented via a variety of output devices, such as a display and/or speaker. The output device could, for example, be stationary, at a fixed distance from the signaling device, such as a roadside display. The output device could be a mobile device, carried in a vehicle or by a user, e.g., a cell phone, GPS navigation system, or personal digital assistant. The system can include a signal timing processor that determines a target average speed of travel between the first and second positions, which can be based on, or calculated from, timing information of the signals and a distance between the two positions.

The external adaptive control system determines a non-linear schedule with one or more states corresponding to one or more individual phases with each state having a start time and a duration. The external adaptive control system generates presence data for reception by the controller assembly for each state and its associated duration.

The storage system examines the number of car images to find license plates in each car image, counts the number of the cars, obtains the status of the traffic lights according to the number of the cars, and manages status of the traffic lights correspondingly.

Abstract: A method of controlling traffic signals at a road intersection, which has a plurality of signal groups, each of which controls at least one direction of traffic within the intersection. The method comprises the steps of obtaining and utilizing traffic data to calculate a current traffic state and the rate of change in the traffic state.

Abstract: A smart traffic control device transmits information to approaching vehicles regarding its current and future state enabling vehicles to control their speed to avoid arriving at the traffic control device until it permits the passage of traffic, thus avoiding stopping, idling and reaccelerating when reaching the traffic control device. In other embodiments the traffic control device or systems receives information from vehicles, transmitting it to other vehicles.

Abstract: In a method for monitoring and controlling traffic states in a road traffic system current or predicted traffic states are determined for one or more points and a distinction is made between the three types of traffic states: free-flowing traffic, slow-moving traffic and stationary traffic. Vehicle inflow into the traffic system is then controlled as a function of the detected traffic states. The state monitoring method is configured to detect phase transitions between free-flowing and slow-moving traffic and/or stationary traffic states, which can be detected or predicted by means of specified criteria. Furthermore, according to the invention the vehicle inflow into the monitored traffic system section is controlled as a function of detected phase transitions between free-flowing and slow-moving traffic.
