speed limit control

基本解釋

Therefore, an effective combination of ramp metering and variable speed limit control is important to achieve a good performance.
由此，匝道調(diào)節(jié)率與可變速度限制間高效的聯(lián)合控制對于提高道路性能顯得尤為重要。
When the traffic demand is too high that ramp metering is not effective anymore, the variable speed limit control is needed to relieve the congestion.
但是當(dāng)高速公路嚴(yán)重?fù)頂D時，匝道控制不再有效，需結(jié)合主線可變限速控制，以緩解交通擁擠。
The critical problem in highway systems was discussed, and action of the main variable speed-limit control of the surveillance and control system of highway was analyzed.
闡述了高速公路運行中存在的主要問題，分析了可變限速控制在高速公路監(jiān)控系統(tǒng)中所起到的作用。
