A user-controlled portable traffic control system comprises one or more traffic signal units and a wireless handheld remote-control unit. Each traffic signal unit provides instruction to approaching motorists via a segmented backlit display consisting of first and second message panels. The wireless handheld remote-control unit allows a user to communicate commands to the traffic signal units via a transceiver circuit. Additionally, the handheld remote-control unit includes an interface indicating system status information via a plurality of indicator lights corresponding to the traffic signal units. Each traffic signal unit is housed in a two-part collapsible rigid outer case with a mounting handle allowing for ease of transport and a versatile means of both mounting and transporting the system.

A portable, self-illuminating traffic sign having a sign face with two opposite sides. One side indicates a first traffic signal, and the other side indicates a second traffic signal. Light assemblies are attached to each side of the sign. The light assemblies emit light that may match the predominant color of one of the sides of the sign. A battery may be disposed in a pole that connects to the sign. A handlegrip allows for the sign to be held and provides a switch to allow for the lights to be selectively turned on and off. The light assemblies are disposed within collar assemblies so as to reduce, or prevent, light emitted from the light assemblies reflecting off of the sign faces.

There is provided an unmanned roadside signage vehicle comprising an autonomous, semiautonomous and/or remotely controllable roadside signage vehicle for various roadside signage, emergency response and maintenance applications. In accordance with one aspect, the unmanned roadside signage vehicle comprises drive motors operably coupled to driven wheels; steering coupled to the driven wheels; a controller for controlling the drive motors and steering; at least one electronic signage board for displaying roadside signage; and a data interface for receiving at least remote control instructions, the data interface operably coupled to the controller and wherein the controller is configured for controlling the drive motors and steering in accordance with the remote control instructions.

A mobile warning device on a vehicle includes a detecting module, a driving module, a monitoring module, and a communication module. The detecting module determines whether the vehicle is unexpectedly immobile. The driving module is detachably set on the vehicle to detach and move the warning device to a specified position when the vehicle is immobile. The monitoring module is used to collect information around the vehicle. The communication module is used to transmit signals between the vehicle, the warning device, and a cloud network.

A system and method are provided, wherein the system includes a traffic control signal, a wireless interface, a mast, a support base, a wireless control device, and a base station for communicating between the wireless interface and the wireless control device. The method involves receiving input from the wireless control device, generating a control signal for operating the traffic control signals, and transmitting the control signal to the traffic control signals.

An alert warning system. In an aspect, alert lights are configured to provide a visual alert and a sound system is configured to provide an audible alert to an approaching vehicle operator. The visual and audible alerts are responsive to a two-part initiation event. The first part of the event initiates the visual alert when the approaching vehicle reaches a first predetermined distance from a safety target. The second part of the event initiates the audible alert when the approaching vehicle reaches a second predetermined distance from the safety target. The second predetermined distance is less than the first predetermined distance.

A road traffic alarm and warning device, moveably mounted to an enclosure of a car and configured to notify a traffic obstacle and coupled to a main controller, includes a first communication unit configured to couple to the main controller and send out a control signal. An operation unit is configured to receive the control signal and output a driving signal according to the control signal and a driving unit is configured to receive the driving signal and move as required driving the alarm device to move out of the enclosure and into action. An alarm system with the alarm device is further disclosed.

A travel height sensor is attached to a front of a pilot vehicle escorting a trailing vehicle hauling an oversized load to alert traffic ahead of the trailing vehicle of the oversized load approaching with the travel height sensor elevated to a highest point of the trailing vehicle and its oversized cargo, wherein the travel height sensor determines whether or not the trailing vehicle and cargo will clear a overhead wire, tree branch, bridge or overpass height prior to incurring damage to the trailing vehicle, its cargo or the overhead obstacle, the travel height sensor making contact with an obstruction below the preset height and subsequently communicating the contact to the driver of the pilot vehicle and driver of the trailing vehicle before the trailing vehicle arrives at the low obstruction, thus avoiding a catastrophic incident.
