Description
Technical field
The present invention relates to a kind of grade separation molded line road of new-type current theory, particularly relate to grade separation molded line road in urban highway traffic system, be specially the flexibility grade separation molded line road that a kind of control is blocked up.
Background technology
In the planning framework of the every bar circuit of city road network, substantially all be made up of section district and crossroad mouth region two large divisions, the size of each section wagon flow traffic flow and the number of track-lines of this section, also there is direct relation with the average passage rate in each track, and present the relation of multiple, wherein arbitrary numerical value changes, and will make this section flow value current in short-term that either large or small change also occurs, have influence on the height of its average daily traffic sometimes.
In existing urban highway traffic system, usual friendship circuit is because of the impact of its discontinuity wagon flow, the impact of large discharge wagon flow can not be adapted to, and grade separation molded line road is in the current running of reality, when current conventional flow, or can normally tackle, but when having multiple emergency case on various nonstandard current behavior and road in current process, or easily cause the indefinite road occupying of various scope and doubling sinuous flow, make the wagon flow in section, local slowly current, and when above situation occurs in large discharge or current peak period, coupling and the restraining factors of adding existing grade separation type line-internal are more, section, local will show gathers around, stifled, the generation of situation such as to squeeze, when obstruction is caused because blocking up in section, local, all a kind of huge waste to time of each side and usefulness.
