BACKGROUND
Field
Embodiments generally relate to a traffic control device or marker (hereinafter collectively referred to as a “traffic control marker”) for highway and/or roadway systems. More particularly, various embodiments are directed to a traffic control marker including a reinforcing member.
Description of the Related Art
Many modern highway and roadway systems utilize traffic control markers, also known as guide posts, delineators, and stakes, to provide a variety of indications to motorists. Generally, traffic control markers can be used to mark the boundaries of roadways or to indicate special access lanes, such as toll lanes or high-occupancy vehicle lanes, though other uses also exist. Some areas of the highway, such as shoulder areas and zones that buffer cars from hazards routinely use traffic control markers to indicate to motorists that these areas are not safe to drive in. Typically, the traffic control marker includes a reflective sheeting partially or completely surrounding the primary tube to provide a distinct indication to motorists at night or through a construction zone. A vehicle's lights reflect off the reflective material on the traffic control marker, thereby indicating to the motorists they should not cross the boundary indicated by the marker.
Generally speaking, traffic control markers are designed and manufactured to survive multiple impacts by vehicles of varying sizes and speeds. One type of traffic control marker is a flexible delineator highway marker, which typically includes a flexible insert positioned in a primary tube of the highway marker to provide it with a rebound effect. In particular, the insertion of the flexible insert into the primary tube of the highway marker allows the marker to return to a substantially upright position after being struck and deflected by a moving vehicle. However, after surviving multiple impact events, a damaged traffic control marker may no longer return to a substantially upright position. If so, motorists may not identify the traffic control marker.
Such a traffic control marker features many parts and requires multiple steps to properly assemble and install the flexible insert into the primary tube, which is subsequently attached to a mounting base of the traffic control marker. Additionally, each of the parts included in such a device is naturally subject to wear over time, requiring the disassembly of multiple parts to repair the damaged traffic control marker.
Thus, it would be desirable to provide a traffic control marker, or flexible delineator highway marker, with a reinforcing member to enhance the structural integrity of the outer or primary tube to prevent it from detaching or deforming from the traffic control marker on impact by a moving vehicle, to improve the functioning life of the traffic control marker, and to maintain the performance of known types of flexible highway markers, when vehicles deflect them on the roadway or other marking area. Such a marker would provide safer roadways for motorists and also provide a cost benefit by reducing the routine service and replacement expenses for traffic control markers.

DETAILED DESCRIPTION
Although the following detailed description contains many specific details for purposes of illustration, it is understood that one of ordinary skill in the relevant art will appreciate that many examples, variations, and alterations to the following details are within the scope and spirit of the invention. Accordingly, the various embodiments described herein are set forth without any loss of generality, and without imposing limitations, relating to the claimed invention. Like numbers refer to like elements throughout.
Referring to FIGS. 1-10, embodiments of a traffic control assembly are shown. A traffic control device, traffic control, assembly, roadside marker, or flexible delineator 100 (hereinafter collectively referred to as “traffic control assembly 100”) for marking roadways or other marking areas is shown.
As shown in FIG. 1, the traffic control assembly 100, in accordance with at least one embodiment, includes a base 110, and a flexible marker or primary tube 120 (hereinafter referred to as “primary member 120”) that extends substantially vertically from the base 110, when the primary member 120 is in a non-impacted and non-deformed state (i.e., not impacted or deformed by a moving vehicle). In accordance with at least one embodiment, the base 110 can attach to asphalt, concrete, or other hard surfaces, and serves as a mounting point by which the primary member 120 may be secured to the ground. In accordance with at least one embodiment, the primary member 120 is sufficiently thick to resist casual bending or flexing along its length from forces, for example, a strong wind. As such, the primary member 120 remains substantially vertically upright, when the primary member 120 is in a non-impacted and non-deformed state. The primary member 120 is sufficiently flexible, so that it will elastically deform along its length, when a physical object forcibly applies a significant impact thereto, for example, by a moving vehicle or automobile.
As further shown in FIG. 1, the traffic control assembly 100 includes a reinforcing member 130 and a retaining member 140.
In accordance with at least one embodiment, as shown in FIG. 1, the base 110 includes a cylindrical and conical shape, while in at least one other embodiment, the base is configured in the shape of a square or rectangle (not shown), or alternatively any other suitable shape. These various shapes may be suitable for uneven terrain to better stabilize the traffic control assembly 100, when the surface of the supporting ground is not level. For example, on a roadway having a sloped shoulder, the base 110 having an elongated shape (e.g., oval with a size of, for example, 4 inches by 18 inches), with a long side of the base 110 being parallel to the roadway, may be used to better follow the contour of the shoulder in which the traffic control assembly 100 is located. The base 110 having a round shape, as shown in FIG. 1, will be discussed in more detail below.
As further shown in FIG. 1, when the traffic control assembly 100 is assembled, the reinforcing member 130 is positioned in a recess in the base 110 and is coupled with the primary member 120.

In an alternate embodiment, the reflective component 180 can be replaced by an alternate reflective material, a light emitting diode, an array of light emitting diodes, or other illumination source that will alert a vehicle to the presence of the traffic control assembly 100. In a light emitting embodiment, the base 110 or other portion of the traffic control assembly 100 can be configured with solar panels and a battery can be housed inside the traffic control assembly 100, such that the traffic control assembly 100 can generate enough electricity during the day to keep them illuminated at night. In an alternate embodiment, the solar panels and/or batteries can be displaced from the traffic control assembly 100. Additionally, in each of the above described embodiments, an illumination source can be placed in the protected inner section of the traffic control assembly 100, such that the lights can be protected from vehicle impacts and can continue to function after an impact or number of impacts. In an embodiment, the lower end of a traffic control assembly 100 can be configured to be embedded in the roadway and the reflective material and protected portion of reflective materials can be configured to face towards oncoming traffic.

In accordance with at least one embodiment, the lower portion 534 of the reinforcing member 130 is configured to include a shoulder 635 such that the retaining member 140 locks the reinforcing member 130.
As further shown in FIG. 6, according to at least one embodiment, the primary member 120 has a lower flange 328, such that the primary member 120 is positioned below the reinforcing member 130. In accordance with at least one embodiment, the upper portion 631 of the reinforcing member 130 includes at least one substantially circumferential cavity 636 and a plurality of substantially circumferential crests.
As further shown in FIG. 6, according to at least one embodiment, the upper portion 531 of the reinforcing member 130 includes an outer substantially circumferential crest 632a and an inner substantially circumferential crest 632b. The at least one substantially circumferential cavity 536 is formed as a result of the inner diameter of the outer substantially circumferential crest 632a being greater than the outer diameter of the inner substantially circumferential crest 632b. In accordance with at least one embodiment, more than one substantially circumferential cavities (not shown) is formed by more than two substantially circumferential crests (not shown). In accordance with at least one embodiment, heights of individual crests (e.g., heights of the outer substantially circumferential crest 632a and the inner substantially circumferential crest 632b), forming the plurality of substantially circumferential crests 632a, 632b may vary. In accordance with at least one embodiment, the at least one substantially circumferential cavity 536 and the primary member 120 are substantially concentric.
In accordance with at least one embodiment, the primary member 120 is sufficiently thick to resist casual bending or flexing along its length from forces, for example, a strong wind. As such, the primary member 120 remains substantially vertically upright, when the primary member 120 is in a non-impacted and non-deformed state. The primary member 120 is sufficiently flexible, so that it will elastically deform along its length, when a physical object forcibly applies a significant impact thereto, for example, by a moving vehicle or automobile.
Although the primary member 120 by itself is sufficiently thick to resist casual bending while being sufficiently flexible enough to maintain a substantially upright position after a vehicle impact event, in accordance with at least one embodiment, the at least one substantially circumferential cavity 536 is configured to provide the primary member 120 additional elastic support perpendicular from a side of the primary member 120. In accordance with at least one embodiment, the force of a moving vehicle impacting the traffic control assembly 600 cause the inner substantially circumferential crest 632b, coupled with the primary member 120, to bend towards the outer substantially circumferential crest 632a then bounce back to its initial substantially upright position.
The traffic control assembly 600, according to various embodiments, having this configuration has non-obvious advantages over conventional traffic control markers with respect to resiliency of the primary member 120 coupled with the reinforcing member 130 and anchoring the primary member 120 coupled with the reinforcing member 130 to the traffic control assembly. In other words, a traffic control assembly 600 having the at least one circumferential cavity 536 can be struck many more times than conventional traffic control markers, which do not have such feature. Such a traffic control assembly 600 provides safer roadways for motorists and also provides a cost benefit by reducing the routine service and replacement expenses for traffic control markers. Markers can be deployed in the hundreds or thousands along highway and roadway sections and thus the added safety benefits and service cost reductions can be substantial.
