Traffic signs that facilitate portability are disclosed. In certain embodiments, they are designed to be lighter and have fewer steps involved in their set up, preferably involving only one person. The design of certain embodiments also allows multiple signs to be transported together, and facilitates air flow through the signs. Certain embodiments include generally horizontal panels with breakaway or fracture paths so as to improve crashworthiness and safety of the traffic sign.

A structure investigation assistance system comprises: a first storage unit that stores image data of a road captured continuously by a camera; a second storage unit that stores detailed information about a structure around the road in association with position information about the structure on a map, the detailed information on the structure being configured using point cloud data obtained by 3D scanning the structure; a first selection unit that selects, from the first storage unit, image data targeted for an investigation request in a case where a request for an investigation of the structure is received; a second selection unit that selects, from the second storage unit, detailed information about the structure targeted for the investigation request; and an information presentation unit that presents a map indicating a location of the structure, the image data selected, and the detailed information about the structure.

A flashing beacon may include a signal unit, a control unit associated with the signal unit, a solar panel or collector, and an activation device that may all be mounted or otherwise positioned on a post of a roadway sign. Light units associated with the signal unit may be programmed to flash on and off in a unique wig-wag pattern. Further, a light bar may also be used with the beacon to generate an intense flash of light soon after activation of the beacon as an additional means of grabbing the attention of the operator of a vehicle.

A roadside signal system and a roadside controller are provided relating to the control and operation of roadside signals and signs, such as those used by departments of transportation and municipalities. The roadside signal system and controller are configured to operate using National Transportation Communications for Intelligent Transportation Systems Protocol (NTCIP) compliant transmissions at both a local and remote level. The roadside controller by itself and as a part of the roadside signal system operates a local network to control multiple signs or signals from a single connection to a central network, thus saving physical space within the roadside cabinets used to store such controllers and virtual network space on the central network.

An apparatus includes a wireless communication system capable of receiving position information for a plurality of workers in a work zone and a position system capable of providing position information for a piece of movable equipment in the work zone. A processor is capable of receiving the position information for the plurality of workers and the position information for the movable equipment and is capable of determining the position of the workers relative to the position of the movable equipment.

A dynamic message sign includes a front housing defining a viewing window and an interior. A LED assembly is in the interior for displaying a message within a cone of vision. A louver assembly limits the cone of vision. The dynamic message sign may also include a back frame for supporting the front housing and a bracket for setting the front assembly at an angle with respect to the back frame. The LED assembly can include a plurality of LED pixels arranged in rows and columns. The louver assembly can include a plurality of louver racks, each louver rack extending adjacent to a column of LED pixels.

A parking space sign system that is placed in a parking space at the interior end and includes a U-shaped flexible bracket defining a base and two opposing arms projecting from the base, a pair of frame mounts adapted for mounting to the projecting arms, at least one sign panel having indicia thereon for placement in one of the frame mounts and an end cap for each end of each frame mount to secure the frame mounts to the flexible bracket. The flexible brackets are preferably made from a rubber-based material used for tires.

A permeable paver and modular light system for making a parking space or a traffic lane using at least one replaceable lighting module or a plurality of replaceable lighting modules, wherein the replaceable lighting module or the plurality of replaceable modules have at least one power supply and at least one light source. The permeable paver and modular light system have a controller configured to turn on and off the replaceable lighting module individually or as a group, change a color of the replaceable lighting module individually or as a group, illuminate a configuration of the replaceable lighting module individually or as a group based on a stored configuration, and change the illuminated configuration of the replaceable lighting module individually or as a group. The permeable paver and modular light system have a plurality of permeable pavers to form a surface for supporting a load of a vehicle.
