  • Patent number: 9576485
    Abstract: One embodiment of a traffic intersection lane and signal system for improving intersection capacity and safety. Through traffic is stopped by signal means (22) a distance away from the intersection. Turning traffic on turn lanes (10) and (14) have an option to proceed and queue on lane segments (12) and (16) respectively, then complete the turning maneuvers during phase ?7 and phase ?1 respectively. The through traffic released from signal means (22) arrives at the intersection at the time opposing left turn phase ?5 expires and through phase ?6 starts, and passes through the intersection without significant delay. A set of detectors (50) and signal means (52) located before the presignal help drivers to make stop decisions, and another set of detectors (54) and signal means (56) located before the intersection provide last second warning to drivers who ran the red light at the presignal. This system accommodates left-handed or right-handed driving conventions.

  • Patent number: 9549686
    Abstract: A time series myoelectric potential signal is acquired, which is representative of time series activity amount of a muscle of a driver when the driver is performing a driving operation on the vehicle, the muscle being involved in the driving operation. Based on the acquired time series myoelectric potential signal, a parameter value indicative of a fluctuation amount of the time-series myoelectric potential signal and an average value of the myoelectric potential signal are obtained. Drivability of the vehicle is evaluated based on the obtained parameter value and the obtained average value.

  • Patent number: 9322137
    Abstract: Method for building structures, particularly passages under operating railways or the like. The invention relates to a method for considerably reducing the occurrence and duration of temporary service interruptions required for building underpasses. After temporarily interrupting service on the tracks (9) and placing said tracks perpendicular to the site in the embankment of the passage that is to be built, the top of the embankment is cleared of soil in order to allow the deck (4) to be built and sealed (7), then the work area is backfilled (8) and the tracks are put back in place in order to allow traffic to resume at the end of the service interruption period. The side walls (10) of the passage are built by digging channels down to the foundation, placing reinforcement and pouring cement therein, then the interior of the passage is graded in preparation for the eventual permanent bottom slab (16).

  • Publication number: 20150078820
    Abstract: The Flow Boulevard concepts provide a system of transportation improvement for urban and suburban existing development and or new development. The system provides the optimization of vehicular capacity and level of service for at grade interrupted flow facilities without the widening of streets. The system is comprised of single and couplet street configurations that allow corridors and networks to be developed that have vehicles flowing without stopping throughout the corridor or network. Benefit of true bus rapid transit is attained by removing the necessity to stop at signals and with only stopping for boarding and alighting of bus riders. Consolidation of population increases in low density settings by introducing medium density corridors can dramatically reduce vehicular miles traveled in suburban locations to conserve resources and reduce greenhouse gases. The system of improvement is both inexpensive by using existing streets and has little impact on existing development by not widening streets.

As a vehicle travels from the first road segment and starts moving across the upper bridge, the upper bridge will rotate downward about the pivot axis and will continue to rotate until the one or more upwardly extending segments of the lower bridge extend through respective openings defined by the upper bridge, at which time the vehicle will transition from driving on the road surface as defined by the upper bridge to driving on the road surface as defined by the upwardly extending segments of the lower bridge. The movement of the upper bridge produces work, which can then be used for power generation.

One version of the intersection includes a protected turn-around lane that allows traffic to turn around and proceed in the opposite direction. The protected turn-around lane provides for a protected turn without having a traffic indicator phase dedicated to protecting such a turn. Another version of the intersection includes an overpass and a protected path through the overpass allowing traffic to turn around and travel in substantially the opposite direction. Another version of the intersection includes an overpass and a protected turn-around lane.

  • Publication number: 20100303544
    Abstract: This method increases the number of lanes immediately preceding and immediately following a given intersection. When the traffic signal is red, vehicles must come to a stop. When the traffic signal turns green, vehicles traverse the intersection and enter the stretch of road immediately following the intersection (3). Of these, vehicles in the priority lanes (6) move on while those in the non-priority lanes must slow and/or stop. When the traffic light turns red and all vehicles from the priority lanes have safely left the area, vehicles in the non-priority lanes can safely merge back into the priority lanes and move on. This method results in a tremendous increase in the traffic flow rate in intersections.

    Abstract: Provided are a vehicle having high degree of operation freedom due to electric power being able to be supplied to the vehicle during its travel and due to the vehicle being able to drive on normal roads, and a traffic system. A large number of overhead lines are arranged over a road. An extendable electric power collector is provided at the rear of the vehicle, and a battery and a drive mechanism are mounted on the vehicle. When the power collector is in contact with an overhead line, electric power supplied from the overhead line is supplied to the battery to charge it and electric power is supplied also to the drive mechanism. When the vehicle travel on a normal road having no such overhead lines, electric power is supplied from the battery to the drive mechanism.

  • Publication number: 20100111601
    Abstract: Systems for improved vehicular movement between first and second crossing roadways. The systems employ multiple turn roadways to permit a vehicle traveling on one of the crossing roadways to appropriately turn and continuously travel onto the other of the crossing roadway. The systems are adaptable to use in conjunction with either left side of the road vehicle movement or right side of the road vehicle movement. In addition, the systems can be adapted for use in conjunction a roadway crossing whereat at least one of the roads is for forwarded vehicle movement in only one direction.

  • Publication number: 20090185856
    Abstract: The present invention relates to the urban roadway system and accompanying underground railway system, which provide the efficient use of limited constructible areas of the congested cities, and also relates to the traffic flow control system capable of the effective control of vehicular movements through the roadways. In the whole or partial areas of a city, the roadway network is constructed and connected in the honeycomb-like net structure. Compared with a typical tetragonal city, the hexagonal city of the present invention can reduce 22% of road extent, 63% of road area and 30% of constructible area in total, and the traffic flow can be improved enormously. The present invention also proves that the hexagonal roadway system enables vehicles to move in average 75% less time without meeting stop-signals by the synchronized signal system for traffic flow controls.
