Relieving urban traffic congestion
View Patent ↗A method of reducing congestion on a roadway is disclosed comprising dividing selected lengths of selected normal lanes of a roadway into two commuter lanes, providing distinctive lane markings to identify the commuter lanes, and dynamically designating selected lengths of selected lanes as either normal lanes or pairs of commuter lanes. In order to dynamically change lane configurations, a set of indicators can be provided as lane markers together with a control system to alter particular lane configurations between normal lanes and commuting lanes both cyclically according to a preprogrammed schedule and dynamically in response to sensed vehicle traffic volume, unusual events such as accidents, weather, and so on. Commuter lanes are designated cyclically and dynamically in response to traffic conditions to increase the capacity of the affected road. Normal lanes are designated at other times. To facilitate entry and exit from designated commuter lanes, transition zones can be provided where entering and exiting commuter lane traffic has right of way. A commuter vehicle is disclosed for use on commuter lanes. A typical commuter vehicle weighs less than 650 lbs., has at least three wheels, an enclosed seating compartment, and a low center of gravity with at least one occupant. In one embodiment, occupants sit in a near-kneeling position to lower their center of gravity. In, an alternate embodiment also providing a low center of gravity, occupants sit in a recumbent position. A mechanism can be provided to raise and lower the seats to facilitate occupant entry and exit. Occupants can be position in-line, one behind the other. Embodiments with two, three, or more seats can be provided.
1. A method of reducing congestion on a roadway, comprising
providing a vehicle roadway having at least one normal lane,
dividing selected lengths of selected normal lanes of said roadway into two commuter lanes, wherein the direction of travel for vehicles in said two commuter lanes is the same as that of the selected normal lane so divided, and wherein conventional vehicles are prohibited from driving in said selected normal lane so divided,
providing distinctive lane markings to identify said commuter lanes, and
cyclically, according to a preprogrammed schedule, and dynamically, in response to sensed vehicle traffic volume or unusual events, designating said selected lengths of selected lanes as either normal lanes or pairs of commuter lanes.
2. The method of claim 1 , wherein said roadway is a freeway.
3. The method of claim 1 , wherein said roadway is a local arterial street.
4. The method of claim 1 , wherein said distinctive lane markings comprise flashing lights.
5. The method of claim 1 , wherein a control system is provided to perform said dynamic designation in response to signals comprising one or more of vehicle sensors on said roadway, notice of unusual events, weather sensors, and weather condition reports.
6. The method of claim 1 , wherein said preprogrammed schedule designates said selected lengths of selected lanes as commuter lanes during certain times and as normal lanes during all other times.
7. The method of claim 1 , wherein each of said commuter lanes can support travel fully within each of said commuter lanes by commuter vehicles having a width of about 2.75 ft, for the full length of each of said selected lengths of selected normal lanes, at speeds at least as fast as the normal speed limit for said selected normal lanes.
8. A method of reducing congestion on a roadway, comprising
providing a vehicle roadway having at least one normal lane,
dividing selected lengths of selected normal lanes of said roadway into two commuter lanes, wherein said selected normal lanes and said commuter lanes are of substantially constant width, and said dividing results in commuter lanes that are substantially parallel to said selected normal lanes, and wherein conventional vehicles are prohibited from driving in said selected normal lane so divided,
providing distinctive lane markings to identify said commuter lanes, and
cyclically, according to a preprogrammed schedule, and dynamically, in response to sensed vehicle traffic volume or unusual events such as accidents or weather, designating said selected lengths of selected lanes as either normal lanes or pairs of commuter lanes.
9. The method of claim 8 , wherein said roadway is a freeway.
10. The method of claim 8 , wherein said roadway is a local arterial street.
11. The method of claim 8 , wherein said distinctive lane markings comprise flashing lights.
12. The method of claim 8 , wherein a control system is provided to perform said dynamic designation in response to signals comprising one or more of vehicle sensors on said roadway, notice of unusual events, weather sensors, and weather condition reports.
13. The method of claim 8 , wherein said preprogrammed schedule designates said selected lengths of selected lanes as commuter lanes during certain times and as normal lanes during all other times.
14. The method of claim 8 , wherein each of said commuter lanes can support travel fully within each of said commuter lanes by commuter vehicles having a width of about 2.75 ft, for the full length of each of said selected lengths of selected normal lanes, at speeds at least as fast as the normal speed limit for said selected normal lanes.
15. A method of reducing congestion on a roadway, comprising
providing a vehicle roadway having at least one normal lane,
dividing selected lengths of selected normal lanes of said roadway into two commuter lanes, wherein the effective vehicle carrying capacity of each of said selected normal lanes is increased by a factor of at least two after said dividing, and wherein conventional vehicles are prohibited from driving in said selected normal lane so divided,
providing distinctive lane markings to identify said commuter lanes, and
cyclically, according to a preprogrammed schedule, and dynamically, in response to sensed vehicle traffic volume or unusual events such as accidents or weather, designating said selected lengths of selected lanes as either normal lanes or pairs of commuter lanes.
16. The method of claim 15 , wherein said roadway is a freeway.
17. The method of claim 15 , wherein said roadway is a local arterial street.
18. The method of claim 15 , wherein said distinctive lane markings comprise flashing lights.
19. The method of claim 15 , wherein a control system is provided to perform said dynamic designation in response to signals comprising one or more of vehicle sensors on said roadway, notice of unusual events, weather sensors, and weather condition reports.
20. The method of claim 15 , wherein said preprogrammed schedule designates said selected lengths of selected lanes as commuter lanes during certain times and as normal lanes during all other times.
