Abstract: A Flow Boulevard system of transportation for existing urban and suburban streets which optimizes vehicular capacity and flow for at grade facilities having intervening crossing streets is provided. The system may be applied to a single street right of way having two-way traffic with a median and enables packs of traffic to continuously flow in both directions concurrently. Flow Boulevards may be connected through interchanges supporting continuously flowing traffic to that connect to couplets of one-way streets to define networks of high vehicular capacity and continuous flowing traffic over large urban areas. Lane signals are provided to optimize traffic flow in each flow boulevard lane and at each interchange.

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.
