摘要:

为了提高道路交叉口通行能力,设计了一种单点交叉口自适应控制系统。系统采用SOPC方案,利用具有NiosⅡ软核的FPGA芯片设计了控制器的硬件,并利用遗传算法建立了信号配时优化模型、VHDL语言进行了遗传算法的硬件化、C语言编写了单点自适应控制器的程序。以成都市温江区南熏-光华大道路口的实测数据为例,进行软硬件系统联调的仿真实验,获得了交叉路口的信号配时优化方案。仿真结果表明,通过采用优化的方案进行交叉口信号配时后,各进口的车辆排队为零。验证了基于NiosⅡ单点在线自适应控制器的设计是有效的。

Abstract:

A single intersection adaptive control system is designed using the SOPC scheme to improve the road intersection capacity.The hardware of the controller is designed using FPGA chip with NiosⅡ,and the signal timing optimization model is established with the genetic algorithm in hardware written in VHDL language and of single point adaptive controller procedure by genetic algorithm in C language.The Wenjiang district intersection data of Chengdu city is simulated as an example of the software and hardware system debugging,and an optimization scheme is obtained for the signal intersection.The simulation results show that for intersection signal by using the optimized scheme,the imported vehicle queue is zero.The design of NiosⅡ single point online based adaptive controller proves feasible and effective.
