A Study on Influence of LRT on Population Shift in European Various Cities

Abstract

On the term of decrease in population in Japan, the compact city , where people can travel by nonmotorized transportation (NMT) such as walk and bicycle and public transportation, is being promoted in local cities. In Toyama city, the plan of compact city based on public transportation such as a light rail transit (LRT) is being promoted recently. The government recommends the residents to live around the stations of LRT. Therefore the authors focus on the population shift in the cities which have LRT systems, then clarify the necessity of LRT system on future compact city’s plans, considering from the population of the city and the area along the LRT line. This research examined 27 cities throughout Europe by performing a detailed analysis of a particular reference to the each city’s population distribution. Moreover the authors picked up particular cities to analyze the population of the area along the LRT line in detail. Then the authors' results showed that how the introduction of LRT affects the population shift.人口減少フレームにある我が国では，人々が徒歩や自転車、公共交通を中心として生活が可能な都市機能集約型のまちづくりであるコンパクトシティが地方都市で進められている．富山市では，LRTなどの公共交通を軸とした拠点集中型のまちづくりが進められており，LRT沿線地域への居住を推進している．そこで，LRT導入都市の人口変動に着目し，都市の人口とLRT沿線の人口の2つの観点から，今後のコンパクトシティ戦略におけるLRT導入の必要性を検討する．本研究では，欧州のLRTが運行している27都市について，LRT導入前後での都市人口の変動を分析した．さらに，その中の4都市に着目し，LRT沿線の人口分布を詳細に分析することで，LRT導入が人口変動にどのように影響しているかを考察する．
