A readily replaceable accessible pedestrian signal station is described including a bottom base plate and a sacrificial base plate.

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.

Apparatus, systems and methods for providing one or more accessories on a support surface include a base releasably engageable with the support surface, a housing configured to carry at least a first accessory and be releasably engaged with the base and an elongated carrier rod configured to carry at least a second accessory and be releasably engaged with the base.

One or more techniques and/or systems are disclosed for alerting workers in a work zone of a potential intrusion by a vehicle. The example system can comprise a detection unit operable to mount to a work zone boundary marker. The detection unit monitors the work zone for intrusion by moving objects using the Doppler Effect. The detection unit can transmit an alarm signal to one or more personnel alerters, such as worn by workers. The personnel alerters can receive the alarm signal and activate an alert, such as an audible, visual, or other sensory alert. In this way, an alert is provided to personnel working in an established work zone that a moving object, such as a vehicle, has penetrated the work zone perimeter. This type of alert may provide the personnel the vital seconds needed to move to safety.

A traffic indicator warning unit for preventing collisions in blind corners has a weather-resistant chassis, a rechargeable battery within the chassis configured to power the unit, an indicator assembly mounted to the chassis comprising a first indicator light configured to indicate to a driver to stop and wait, and a second indicator light configured to indicate to a driver that the unit is non-operational, and further a motion-detector mounted to the chassis, configured to detect a moving vehicle near the unit, a metal detector mounted to the chassis, configured to detect the metal in a vehicle near the unit, and a transmitter/receiver within the chassis having an antenna, wherein the transmitter/receiver is configured to communicate with one or more other traffic warning units. A method of use of a traffic indicator warning system for a blind corner system is also disclosed.

A positionable warning sign device provides a portable unit which facilitates identification of a traffic hazard. The device includes a primary member, a first arm, and a second arm. The first and second arms are coupled to the primary member and pivotally positionable to form an end of an arrow. Light emitters are coupled to respective front walls of the primary member, the first arm and the second arm. Arcuate projections extend from the primary member defining a receiver. A projection extends upwardly from a top end of a tripod. An upper portion of the projection is insertable into the receiver whereby the primary member is coupled to the tripod and supported on the lip. A power supply is operationally coupled to the plurality of light emitters.

A pole mounting system can be configured as a center drawn mounting system which allows the user to securely mount and adjust the inner stanchion in various rotational orientations about the vertical axis. The system also allows any electrical wiring or other conduit to be run up inside of the pole. Once the inner stanchion is fastened in place, the outer stanchion fits over top with a first disc on the outer stanchion interlocking with a disc recess on the inner stanchion, thereby preventing the outer stanchion from twisting with respect to the inner stanchion. Once a locking bolt is in place, the parking meter is fastened to the top of the outer stanchion. The present system is tamper resistant because the electrical wiring or conduit and the mounting hardware are not externally accessible once installation is completed.

The system also allows any electrical wiring or other conduit to be run up inside of the pole. Once the inner stanchion is fastened in place, the outer stanchion fits over top with a first disc on the outer stanchion interlocking with a disc recess on the inner stanchion, thereby preventing the outer stanchion from twisting with respect to the inner stanchion. Once a locking bolt is in place, the parking meter is fastened to the top of the outer stanchion.
