【摘要】：結(jié)合成都市48路公交線路全天車輛自動(dòng)定位(automatic vehicle location,AVL)數(shù)據(jù),定量分析公交運(yùn)行可靠性及其相關(guān)關(guān)系。對比證明區(qū)間運(yùn)行時(shí)間均值與其標(biāo)準(zhǔn)差的對數(shù)呈現(xiàn)更為顯著的線性關(guān)系后,量化指標(biāo)區(qū)段長度、信號交叉口個(gè)數(shù)、公交專用道長度、站點(diǎn)個(gè)數(shù)、時(shí)間段,并細(xì)化指標(biāo)沿線土地利用性質(zhì),建立多元線性回歸模型以解釋造成區(qū)間運(yùn)行時(shí)間波動(dòng)的原因。考慮到不可靠性會隨著車輛的運(yùn)行而逐步向后續(xù)區(qū)段傳播的特性,提出了在因變量中加入前一區(qū)段運(yùn)行波動(dòng)性這一指標(biāo),以從時(shí)間和空間兩個(gè)層面探究造成公交運(yùn)行不可靠的原因,最終證明區(qū)段間公交運(yùn)行可靠性存在較強(qiáng)的關(guān)聯(lián)性。
[Abstract]:With the 48 Chengdu city bus lines all day long (automatic vehicle automatic vehicle location location, AVL) data, quantitative analysis of the reliability of the bus and the relationship between the running time interval. By comparing with the standard logarithmic mean difference is more significant linear relationship, quantitative indicators section length, the number of signal intersection, bus lane length the site, the number of time periods, and detailed index of land use along the nature, the reason for establishing multiple linear regression model to explain the cause of interval running time fluctuation. Taking into account the reliability with the operation of the vehicle and gradually spread to the subsequent section characteristics, proposed by adding this index in the previous section run volatility variables in order to explore, from two aspects of time and space caused by the bus operation is not reliable, finally prove the existence of strong correlation between the reliability of bus section .
