Abstract
An interchange for road and freeways that allows for a constant movement of traffic via entrances and exits from a circular road accessible from all directions.
Description
- This invention relates to an road and freeway interchange that can be built at a lower cost than prior art interchanges, and can allow traffic to not stop at intersections, which saves fuel, and reduces time sitting at stop lights.
- A safer and cost effective interchange layout applicable to primary road interchanges at a freeways as well as freeway to freeway Interchanges is sorely needed for areas with limited right of way (ROW) or limited budgets. The current interchange library consists of designs with several conflict points regulated by using signals or stop operations. It is inferred from safety records and cost data for the current systems that an alternative is needed.
- The present invention is a new tool for interchange designers and for Transportation Agencies to consider. This may also be referred to as a road grade separation. The present invention has the potential to become the interchange standard for the country.
- A safer and cost effective interchange layout applicable to Primary Road To Freeway Interchanges as well as Freeway to Freeway Interchanges. It primarily relies on traffic free flow movement within the interchange without signals or stop operations. Benefits of using the present invention include (1) increased safety, (2) efficient, (3) simple, (4) flexible, (5) less expensive to construct, (6) environmentally friendly (7) relies on tested construction and design procedures.
- There is a need to create a road and freeway interchange that is intuitive to users.
- There also exists a need to create an interchange that does not need traffic signal, and also eliminates the need for emergency power generators for signals.
- There is also a need to eliminates hot spot emissions associated with signalized urban interchanges.
- There is also a for an interchange that reduces chances of wrong-way entry onto freeways.
- There is also a need for an interchange to perfect maintenance of traffic during construction since most of the system can be built off-line.
- There is also a need for an interchange that is very effective at depressed freeway locations.
- There is also a need for an interchange that has multiple road safety advantages, including, but not limited to:
-
- a Eliminates directional conflict points for all movements
- b. Eliminates platooning associated with signals
- c. Eliminates weave-merge movements on freeways
- d. Provides turning radii twice as long as loop ramps for the same ROW
- e. Redundant ramp (FTF) system allowing for a bypass in case of accidents
There is also a need for an interchange that has multiple road design advantages: - a Eliminates weave-merge movements on freeways
- b. It requires a small foot print making it applicable for tight ROW locations
- c. Accommodates sharply skewed road alignments
- d. Accommodates irregular intersections and multi-leg roads at interchanges
- e. Applicable to divided and undivided highways
- There is also a need for an interchange that has multiple bridge advantages:
-
- a Eliminates the need for high and long ramp bridges for indirect freeway to freeway movements
- b. Reduces a four level freeway interchange to a three level freeway interchange
- c. Eliminates the need for separate infrastructures for AM and PM peak traffic volumes
- d. Requires shorter span bridges allowing for smaller beams sections and increased vertical clearance without raising approach roadways.
- There is also a need for an interchange with the following advantages, replacing eight ramps with four; easy maintenance of traffic (MOT) since the new bridges and circular road can be built off main line; eliminates weave merge lanes on the freeway; no collector-distributor (CD) roads, as required for modern Cloverleaf Interchanges; reduces chances of wrong-way entry onto the freeway; no traffic signals are needed; eliminates the need for emergency power generators for signals; it requires a small foot print allowing it to fit the ROW; it requires a small foot print making for proper and grading without guardrail; eliminates emission hot spots associated with signalized urban interchanges; reduces the pavement area on ramps and roads. Lane splitters can be added, if needed for capacity
