An on-board intelligent vehicle system includes a sensor assembly to collect data and a processor to process the data to determine the occurrence of at least one event. The data may be collected from existing standard equipment such as the vehicle communication bus or add-on sensors. The data may be indicative of conditions relating to the vehicle, roadway infrastructure, and roadway utilization, such as vehicle performance, roadway design, roadway conditions, and traffic levels. The detection of an event may signify abnormal, substandard, or unacceptable conditions prevailing in the roadway, vehicle, or traffic. The vehicle transmits an event indicator and correlated vehicle location data to a central facility for further management of the information. The central facility sends communications reflecting event occurrence to various relevant or interested users. The user population can include other vehicle subscribers (e.g., to provide rerouting data based on location-relevant roadway or traffic events), roadway maintenance crews, vehicle manufacturers, and governmental agencies (e.g., transportation authorities, law enforcement, and legislative bodies).

This maintenance decision-making support includes communication components and processing modules that integrate data from multiple external sources to locally simulate conditions on, and generate treatment recommendations for, local roadways and transportation network segments based on user-selected parameters.

The present invention is designed to complement the existing transportation infrastructure in order to alleviate ever-worsening traffic congestion in problematic areas by minimizing the impact of driver “bunching” habits and/or external events that lead to congestion problems. Events alleviated by the present invention may happen at naturally occurring roadway infrastructures such as merges, lane shifts, and exits, and under conditions like rush hour, accidents, stand-stills, and HOV lane activation times. Further, vehicles allowing their speed and spacing to be controlled should have access to high-flow lanes. This invention will best and most safely be implemented at low speeds when congestion is most problematic and bunching habits prevent the dissipation of gridlock. In particular embodiments, the invention will regulate multiple vehicle accelerations (non-negative acceleration) once a low threshold speed has been reached through the transmission of signals to receivers in properly equipped vehicles. The exclusive non-negative acceleration control system simplifies the manufacturing, safety and redundancy necessary for implementing such a system and is commercially viable.

The technology described herein provides for the creation of an atmospherically-lifted multi-tethered structure in a semi-stationary position in the atmosphere, which supports cabled cargo handling operations within the three-dimensional space beneath the structure, allowing cargo loads to move directly from source to destination in that same space (between the ground and the atmospherically-suspended structure itself). The design combines a highly configurable aerial platform with the usefulness of complex cargo transportation systems to enable transit both at high speeds over long distances, and at low speeds on the localized level. Constant atmospheric lift from buoyancy and wind effects allows for a flexible transportation infrastructure over a broad three-dimensional area.

The Environment Adaptive Electric Vehicle (EAEV) is capable of operating in a number of operating environments such as on a conventional highway, or on an elevated mainstream transportation infrastructure and also on a variety of local, low velocity, low volume, automated and semi-automated transportation infrastructures that may serve as collector roads for vehicles to access the mainstream elevated integrated bimodal infrastructures. The EAEV has a variety of sensors, receivers, cameras, monitoring devices, magnetic readers, GPS built into the vehicle. In a typical vehicle all of this information would be interpreted and applied in the same way. In the EAEV the vehicle wants to know what environment it is in. It then uses the software that defines that environment for all of its decisions. As a result, the EAEV uses the same equipment and similar information that is received over the equipment but applies it differently depending on what kind of system the vehicle is travelling on.
