駐車場案内システムによる案内効果に関する検討

摘要

駐車場案内システムによる案内効果を比較するために、セルオートマトンモデルによるシミュレータを構築し、これを用いて、通過交通のない状況で目的地までの往復の平均旅行時間を測定した。東京都江戸川区から千葉県市川市の道路網において、駐車場案内なし、案内システム、実際の駐車場案内という3つの状況について平均旅行時間を比較したところ、駐車場案内の効果が示されるとともに、案内システムと実際の案内には大差がないという結果が示された。%In this paper, we describe about guidance effects of parking guidance system by traffic simulator. For comparison guidance effect by the system, we constructed a cell-automaton simulator. To evaluate pure guidance effect by the simulator, we have measured total trip time between origin and destination, to go and come back, without passing traffics. Driver's parking choice feature is based by reference No.(3). So if a driver does not understand any parking statement, (this thing means, there is no parking guidance system), the driver chooses a nearest park from own destination. If drivers are provided the information by standing guide boards, they consider parking statement (full congestion or empty), and they choose parking location. The information of parking statement is renewed at any intersections where the guide boards stand. And we define the driver's parking choice feature, if driver can be provided right parking statement, destination and parking location. We compare with guidance effect under these environments. An application area is east Tokyo to west Chiba along the Edogawa-river, and this area includes some living zones. The parks in this area are integration managed by the system, we show quantitatively evaluation values of guidance effect.
