【摘要】：近年來高速公路、高速鐵路等快速交通不斷發(fā)展,城市區(qū)域可達(dá)性得到大幅提高。基于柵格數(shù)據(jù)的成本加權(quán)距離法,利用平均旅行時(shí)間、等時(shí)圈以及日常可達(dá)性等區(qū)域可達(dá)性指標(biāo),比較分析有無高速公路和有無高速鐵路情況下長(zhǎng)三角地區(qū)中心城市可達(dá)性空間格局變化,探索兩種快速交通方式對(duì)中心城市可達(dá)性的影響差異。結(jié)果顯示:由于高速公路網(wǎng)發(fā)育程度較好,對(duì)城市區(qū)域可達(dá)性的影響較為均衡,而高速公路橋能顯著縮短兩岸旅行時(shí)間;高速鐵路運(yùn)行速度更快,但主要沿大城市帶呈線狀分布,因此對(duì)沿線可達(dá)性改善明顯,尤其是對(duì)鐵路端點(diǎn)城市;高速鐵路較高速公路對(duì)城市之間日�？蛇_(dá)時(shí)間優(yōu)化效果顯著;高速公路和高速鐵路對(duì)于可達(dá)性影響各異,需銜接配合方能大幅提高城市日�？蛇_(dá)性,促進(jìn)區(qū)域經(jīng)濟(jì)社會(huì)公平快速發(fā)展。
[Abstract]:In recent years, with the rapid development of expressway and high-speed railway, the accessibility of urban area has been greatly improved. The cost weighted distance method based on raster data makes use of the average travel time. The regional accessibility indexes such as isochronous circle and daily accessibility are compared and analyzed, and the spatial pattern of accessibility in the central cities of Yangtze River Delta region is compared and analyzed under the condition of whether there is a highway or not and whether there is a high-speed railway. This paper explores the difference between the two modes of rapid traffic on the accessibility of central cities. The results show that the impact on the accessibility of urban areas is more balanced due to the good development of the expressway network. The highway bridge can significantly shorten the travel time between the two sides of the strait; The speed of high-speed railway is faster, but it is mainly distributed linearly along the big city zone, so the reachability along the railway line is improved obviously, especially for the railway terminal city. Compared with the expressway, the high-speed railway has a remarkable effect on the optimization of the daily reachable time between the cities. The influence of expressway and high-speed railway on accessibility is different, so the daily accessibility of city can be greatly improved and the regional economy and society can be developed fairly and rapidly.
