本文提出了利用Excel VBA作为主控程序将VISSIM与MATLAB进行集成构建仿真平台的方法,解决了直接对VISSIM二次开发编程难度大、耗时长的问题.该方法综合Excel VBA与VISSIM、MATLAB的接口编程容易,且MATLAB具有强大的工具箱、库函数和擅长处理矩阵的优点,其中VISSIM和MATLAB作为Excel VBA的调用对象,利用MATLAB编制新建交通控制模型的代码,利用VISSIM模拟车流运行和提取各种交通运行性能指标.具体地,VISSIM与Excel之间采用COM数据通讯接口进行集成,Excel与MATLAB之间采用Excel Link扩展接口进行集成.采用这种方法建立的交通控制仿真平台为研究验证新型的交通控制模型提供了有效途径,最后给出了一个基于该控制仿真平台建立的Q学习配时优化模型的实例.

The synergy of single atoms （SAs） and nanoparticles （NPs） has demonstrated great potential in promoting the electrocatalytic carbon dioxide reduction reaction （CO2RR）;however,the rationalization of the SAs/NPs proportion remains one challenge for the catalyst ***,a Ni2+-loaded porous poly（ionic liquids）(PIL) precursor synthesized through the free radical self-polymerization of the ionic liquid monomer,1-allyl-3-vinylimidazolium chloride,was pyrolyzed to prepare the Ni,N co-doped carbon materials,in which the proportion of Ni SAs and NPs could be facilely modulated by controlling the annealing *** catalyst Ni-NC-1000 with a moderate proportion of Ni SAs and NPs exhibited high efficiency in the electrocatalytic conversion of CO2into *** Ni K-edge X-ray absorption near-edge structure （XANES） spectra and theoretical calculations were conducted to gain insight into the synergy of Ni SAs and *** charge transfer from Ni NPs to the surrounding carbon layer and then to the Ni SAs resulted in the electron-enriched Ni SAs active *** the electroreduction of CO2,the coexistence of Ni SAs and NPs strengthened the CO2activation and the affinity towards the key intermediate of*COOH,lowering the free energy for the potential-determining*CO2→*COOH step,and therefore promoted the catalysis efficiency.

Prigogine-Herman交通流中观模型的超车概率公式仅是密度的函数,是线性的,没有考虑超车需求。利用期望速度对超车概率公式进行改进,提出了新的非线性超车概率公式,并建立了相应的交通流中观模型。改进的模型能够同时考虑车流密度和超车需求,更加真实地反映交通流运行。利用新模型对车流从高密度区向低密度区的扩散过程进行了模拟,分析了线性超车概率公式和Greenshields抛物线型超车概率公式的区别。结果表明:采用线性超车概率公式时速度分布演化较快,且全部集中在3个速度类;采用Greenshields抛物线型超车概率公式可以反映速度分布演化的过程,且速度分布收敛为6个速度类,更加符合实际。
