A method has steps for dividing a controlled roadway into virtual moving packets with characteristics of being spaced apart by a specific distance and moving at a controlled speed on the roadway, by a master computer coupled to sensors and actuators of the controlled roadway, managing vehicles traveling on the controlled roadway to enter, leave and occupy individual ones of the virtual packets, through communication by the master computer with on-board computers in individual ones of the vehicles, and adjusting virtual packet size and spacing during operation, causing vehicles occupying the spaces of the virtual packets to readjust position relative to one another according to the size and spacing adjustment of the packets by the master computer.

A crane mat is disclosed having a plurality of panels of lumber positioned in alternating transverse directions with respect to one another, where the top and bottom panels are oriented parallel to the direction of vehicular traffic. The top and bottom panels may include a plurality of spaced apart grooves extending longitudinally from a first longitudinal end of the crane mat to a second longitudinal end of the crane mat for enhancing traction of a vehicle when traversing across the crane mat by transporting rain or moisture off the mat, or for receiving mud or other debris. The crane mat may include a plurality of edge protectors positioned on respective sides of the crane mat to protect the crane mat from handling damage. In various embodiments, the crane mat may be manufactured using either softwood, hardwood, or any combination of softwood and hardwood.

Disclosed are interlocking elongate composite bamboo industrial mats having an upper layer with two or more elongate laminated composite bamboo panels, an intermediate layer with a plurality of elongate laminated composite bamboo panels arranged in parallel and perpendicular to the laminated composite bamboo panels in the upper layer, and a bottom layer with a plurality of elongate laminated composite bamboo panels arranged in parallel to the upper layer. The three layers are secured together with fasteners consisting of a bolt, an outward-facing concave washer engaged with the bolt head, and a sleeve nut having an outward-facing washer engaged with the sleeve nut head. The interlocking elongate composite bamboo industrial mats are configured to interlock end-to-end or alternatively, side-to-side. Each of the elongate laminated composite bamboo panels comprises a plurality of kiln-dried glue-dipped elongate asymmetrically fractured bamboo strips compressed into a solid panel devoid of air spaces.

Provided is a technique including: a main dolly that includes a cargo platform, three or more wheels supporting the cargo platform, and a handle connected to the cargo platform; and a sub dolly that is configured to be movable between a position on the cargo platform of the main dolly and a position outside the cargo platform, wherein the sub dolly includes a front wheel and a rear wheel enabling the sub dolly to move at least in a forward and backward direction, a holder configured to hold an object so that its center of gravity ahead of the front wheel, and a counterweight detachably provided behind the front wheel, and the main dolly is configured to be capable of carrying and conveying the sub dolly in a state of holding the object.
