【摘要】：隨著城市機(jī)動(dòng)車輛的增多，交通擁堵也越來越嚴(yán)重，交通控制方法隨之成為降低交通壓力、緩解交通擁堵的重要方法。在交通控制中最常用的控制方法一般分為兩種：軟控制和硬控制。軟控制包括可變信息標(biāo)志、可變限速系統(tǒng)、道路標(biāo)志標(biāo)線等，主要起到誘導(dǎo)作用，誘導(dǎo)車輛安全通行；硬控制包括信號(hào)燈控制及減速壟等，能夠強(qiáng)制車輛減速行駛，保證駕駛員行車安全。無論是軟控制方法還是硬控制方法，目的為了解決城市交通和道路安全問題、改善道路交通條件、提高道路通行率、減少交通事故，但是由于上述方法控制作用不明顯、不能均衡路網(wǎng)流量等缺點(diǎn)，需要新的控制方法在更高層次上滿足社會(huì)大眾的需求及服務(wù)交通。 本論文在研究國內(nèi)外現(xiàn)狀的基礎(chǔ)上，針對交通限速控制方法中軟硬控制的特點(diǎn)，，提出了動(dòng)態(tài)限速控制方法。該方法對于超過限定速行駛的車輛產(chǎn)生明顯且安全的顛簸，對于未超過限定車速行駛的車輛則平穩(wěn)放行，通過視覺警示和超速顛簸反饋?zhàn)饔糜隈{駛?cè)耍ㄟ^行為控制實(shí)現(xiàn)對車輛的限速通行控制。在此基礎(chǔ)上分析研究了速度、密度和流量關(guān)系，基于LWR模型和基本元胞傳輸模型建立基于密度的元胞傳輸模型，即動(dòng)態(tài)限速控制模型。結(jié)合北京市東四環(huán)快速路的進(jìn)出口匝道進(jìn)行仿真驗(yàn)證，驗(yàn)證了本文提出的動(dòng)態(tài)限速控制方法和理論模型的可行性。
[Abstract]:With the increase of urban motor vehicles, traffic congestion is becoming more and more serious, and the traffic control method has become an important method to reduce traffic pressure and alleviate traffic congestion. The most commonly used control methods in traffic control are divided into two kinds: soft control and hard control. Soft control includes variable information signs, variable speed limit systems, road signs. Marking line and so on, mainly play an inducement effect, induce vehicle safe passage, hard control including signal lamp control and deceleration ridge, which can force the vehicle to slow down and ensure the driver safety. The purpose is to solve the problem of urban traffic and road safety, improve the road traffic conditions and improve the road. Road traffic rate, reduce traffic accidents, but because of the above methods of control is not obvious, can not balance the road network flow and other shortcomings, the need for new control methods at a higher level to meet the needs of the public and service traffic.
On the basis of studying the current situation at home and abroad and aiming at the characteristics of the soft and hard control in the traffic speed limit control method, a dynamic speed limit control method is proposed. This method produces a clear and safe bump for the vehicles running over the speed limit, and runs smoothly for the vehicles running without a limited speed, through the visual warning and the overspeed. On the basis of the LWR model and the basic cellular transport model, the density based cellular transmission model, that is, the dynamic speed limit control model, is built on the basis of the LWR model and the basic cellular transport model, which combines the import and export of the East Fourth Ring Expressway in Beijing. The simulation of ramp shows that the proposed speed limit control method and theoretical model are feasible.
