improve its service level, the long term evolution of willingness-to-use (WTU) and thetime-spatial distribution of DRSTS demands should be well modelled. This project focuses on
the mechanisms of customization behavior on the supply-demand evolution of DRSTS service,
which may provide theoretical foundation and scientific basis for improving the supply capacityand operation efficiency of share transportation system.

࣭In this study, the characteristics of the DRSTS service in Dalian City, China, including travel
characteristics of different subscriptions and spatial features, were analyzed based onlong-term travel demand data of DRSTS users. The performance of the current DRSTS wasevaluated based on five performance metrics and compared with those for public
transportation (PT), bicycles, taxis, and private cars. The average travel speed (ATS) andnumber of stops (NOS) were used as the performance metrics for each O-D pair of eachtravel mode. The difference arrival time(DAT) is a performance metric that can be used todescribe the level of punctuality and reliability of the public transit service. The travel
expense (TE) and travel time (TT) were chosen as the travel cost metrics.
࣭The DRSTS is a mode which coexist and compete with PT but not a complement in areas
with poor level of service of traditional public transportation. More fluctuated daily
subscriptions indicate that minibus is more suitable to serve the random demands in order forgetting higher occupancy ratio easily. Commuters are main DRSTS users especially for themonthly subscription. The travel expense of DRSTS is three times higher than that of PT, but
it is significantly lower than those for taxis and private cars, especially for monthly
subscriptions. Parking fees play a significant role in high travel expense of private car andmake DRSTS quite attractive for person who drive to commute.

࣭In order to examine the long term evolution of willingness-to-use (WTU) of DRSTS demands,
this work proposed a user loyalty model to investigate user subscription duration times and themechanism of subscription behaviors based on long-term subscription records andorigin-destination information of DRSTS users in Dalian City, China. This work fills the researchgap on user loyalty for DRSTS. The results show that travel time, travel speed, travel expense,
gender, order of boarding station for users, length of continuous subscription period, availabilityof rail transit, etc., have significant influences on user loyalty. In particular, the time reduction intransferring and detouring of a trip has a significant effect on strengthening the user loyalty for
DRSTS. Moreover, the unobserved heterogeneity of service quality at different stages in the
progress of the DRSTS significantly contributes to loyalty deviation. The loyalty model proposedand calibrated in this work was demonstrated to be well-fitted and robust. It provides a method of
forecasting the evolution of the number of passengers and can serve as a policy-making reference
to build a diversified and attractive public transportation system.

１．研究目的
交通事故は当事者の死亡，身体損傷等の人的損失や車両，構造物等の損壊による物的損失，交通事故に関連して発生する社会福祉費用，救急費用，車両・医療設備費用，裁判費用，保険運営費といった各種公的機関等において発生する損失等を引き起こす．また交通事故渋滞による環境負荷ももたらす．本研究では，交通事故頻度分析により交通事故多発地点を特定し，交通事故防止・軽減対策による交通事故削減効果および事故渋滞による環境負荷削減効果を算出することを目的とする．特に，交通事故発生危険個所は事故種別によって異なり，さらに，事故種別によって効果的な防止・軽減対策も異なるため，事故種別を区別した交通事故分析が必要である．本研究では，事故種別間の相関を考慮した交通事故頻度分析により，効率的な交通事故対策および環境負荷削減を可能とすることを目指す．

２．研究内容と成果
愛知県豊田市を対象として，2006 年から 2015 年の 10 年間に発生した交通事故デー
タを事故種別及び事故発生地点別に分類し事故データベースを構築した．本データベー
スでは，交差点で発生した交通事故に着目し，運転者の年齢階層別の各交差点での交通事故数を集計した（Figure 1）．
上記のデータベースを用いて運転者年齢階層（若者，一般，高齢者）別の交通事故頻度モデルを構築し，交通環境や周辺条件が交通事故数に及ぼす影響を定量化した．ここでは，データベースには交通事故が 1 件以上発生した交差点のみが含まれており，交通事故が発生していない交差点が含まれていないことから，ゼロ切断モデルを適用した．
さらに，本研究では，運転者年齢階層別の交通事故頻度に及ぼす交通環境の影響を個別に定量化するために，多変量ポアソンモデルを適用した．尤度関数は以下の式で与えられる．ここで，分母はいずれかの運転者年齢階層の交通事故数がゼロでない確率を表す．
