【摘要】：傳統(tǒng)拓?fù)渚W(wǎng)絡(luò)級(jí)聯(lián)失效可靠性模型,大多忽略路網(wǎng)設(shè)施與運(yùn)輸需求的空間分布問(wèn)題。在復(fù)雜分層網(wǎng)絡(luò)結(jié)構(gòu)模型基礎(chǔ)上,提出了城際路網(wǎng)的級(jí)聯(lián)失效可靠性仿真模型,對(duì)中國(guó)內(nèi)地城際路網(wǎng)的可靠性進(jìn)行了實(shí)例仿真研究。仿真數(shù)據(jù)表明:穩(wěn)定配流狀態(tài)下,長(zhǎng)三角、環(huán)渤海、京津唐、珠三角地區(qū)OD負(fù)載聚集程度最高。當(dāng)OD總量大于一個(gè)臨界值時(shí),針對(duì)高OD負(fù)載區(qū)域路段的蓄意攻擊,容易引起城際路網(wǎng)系統(tǒng)的級(jí)聯(lián)崩潰,其中長(zhǎng)三角地區(qū)對(duì)蓄意攻擊最為敏感。實(shí)驗(yàn)結(jié)果顯示,該模型能夠有效仿真分層網(wǎng)絡(luò)的空間結(jié)構(gòu)特征對(duì)路網(wǎng)級(jí)聯(lián)失效可靠性的影響作用。
[Abstract]:The traditional topology network cascade failure reliability model mostly ignores the spatial distribution of road network facilities and transportation demand. Based on the complex hierarchical network structure model, the cascade failure reliability simulation model of intercity network is proposed, and the reliability of intercity network in mainland China is studied by an example. The simulation data show that the OD load concentration is the highest in the Yangtze River Delta, the Bohai Sea, the Beijing-Tianjin-Tangshan and the Pearl River Delta. When the total OD value is greater than a critical value, the intentional attack on the section of high OD load area is liable to cause the cascade collapse of the inter-city network system, especially the Yangtze River Delta region is the most sensitive to deliberate attack. Experimental results show that the model can effectively simulate the effect of spatial structure characteristics of hierarchical network on the reliability of cascade failure of road network.
