Abstract: 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.

Abstract: A computerized system for guiding activity in a current construction project has digital memory storing information about completed and current construction projects, at least one input mechanism for a user to provide information to the digital memory concerning the current construction project, a processor system for accessing information in the digital memory, processing said information, and providing output available to a user of the computerized system, and software guiding the processor in its accessing information, processing the information, and in providing the output. Considering a current project, the software accesses information regarding one or more completed projects as well as information concerning the current project, processes the information, and provides output specifying one or more actions to be taken in the current project.

Abstract: A transit system has an elevated controlled roadway system, a plurality of powered transport vehicles with steerable front wheels having a common width dimension, and both manual controls and an on-board computer (OBC) system for control on the elevated roadway, a master computer system communicating with the OBCs, enabled thereby to determine location of transport vehicles and to control velocity of the transport vehicles, and outwardly-angled guide curbs along opposite sides of the roadway surface, and spaced apart at a dimension larger than the common width dimension. The front wheels of the transport vehicles, by virtue of the angle of the guide curbs, provide a region of contact to vehicle wheels only at a relatively thin line near the outside diameter of each wheel, and wherein the guide curbs or the front wheels at the region of contact, or both, are surfaced with a low-friction material.

Abstract: In a vehicle guideway having a vehicle track, a guidance system is provided comprising one or more guide curbs installed along a length of the guideway, and a low-friction coating or coatings presented by the curbs, a vehicle's tires, or both, the coating or coatings reducing friction and wear in the event of contact between the tires and the one or more guide curbs.

Abstract: A method of constructing an elevated roadway, utilizing a crane having an articulated boom arm and a gripping mechanism, at the end of the arm for gripping a pylon, below a roadway cradle of the pylon, in order to temporarily transfer loads, generated by a tramway moving a precast bridge section along the crane arm and onto a pair of cradles, mounted upon the pylons. The construction method permits the crane to be positioned on an assembled portion of the elevated roadway, while constructing the remaining portion of the elevated roadway.

Abstract: A cast-concrete simulated log has a longitudinal axis and an outside surface simulating a natural log appearance, and also has at least one triangular rebar reinforcement embedded in the concrete in a plane at substantially a right angle to the longitudinal axis, with corners of the triangular rebar exposed at the outside surface, such that the exposed corners of the rebar triangle are available as connection points for attachment to other structures or for lifting and manipulating the log. In some cases there are two or more embedded rebar triangles spaced along the length of the log, and the concrete is colored to simulate the color of a natural log. Concrete logs are assembled to simulate large-woody-debris.

Abstract: A unique transit system incorporates at least one internally powered, wheeled, transport vehicle having both manual controls enabling a user to drive the vehicle on a surface street and an on-board computer (OBC) system enabling software control of at least vehicle steering and velocity. A controlled roadway system having a roadway surface upon which the transport vehicle runs on its internal power on the same wheels as on surface streets is provided as well. On surface streets off the controlled roadway the manual controls are active, and on the controlled roadway the software controls are active. Manual or computer control depends on whether the vehicle is on the controlled roadway or surface streets. The OBC communicates with a Master computer for the controlled roadway, providing a range of functions. The transport vehicles operate at a fixed and constant speed on the controlled roadway system.
