The first and second traveled ways cross over the third and fourth traveled ways. Each of the first and second traveled ways has a design speed compatible to a highway or freeway design speed, or is designed according to highway or freeway design standards. Each of the third and fourth traveled ways has a design speed compatible to the design speed of a street, road, or a conventional highway, or is designed according to the design standards of a street, road, or a conventional highway. In the preferred embodiment, the first traveled way left turn ramp crosses over the third and fourth traveled ways, then crosses under the first and second traveled ways, and finally joins the fourth traveled way. The second traveled way left turn ramp crosses over the third and fourth traveled ways, then crosses under the first and second traveled ways, and finally joins the third traveled way. In the additional embodiment, the third traveled way left turn ramp crosses under the first and second traveled ways, then crosses over the third and fourth traveled ways, and finally joins the first traveled way. The fourth traveled way left turn ramp crosses under the first and second traveled ways, then crosses over the third and fourth traveled ways, and finally joins the second traveled way. The present invention eliminated the highway and street weaving sections. Each fly over or under ramp achieves minimal number of horizontal curve, slope, and sag and crest, which represents better alignment and profile than the one in the interchange in U.S. Pat. No. 4,861,184. Therefore, the present invention has higher efficiency and safety standard than a conventional cloverleaf type local interchange and the interchange in U.S. Pat. No. 4,861,184. The two level configuration, improved ramp geometric design, higher safety, and better efficiency make this interchange a better choice for congested urban highway system. | 10-30-2008 |

| 20150078820 | Flow Boulevard; continuous flowing traffic on interrupted urban streets - 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. | 03-19-2015 |
