Descriptive analysis of detouring traffic through neighborhood streets using probe car data

Seishu Kitamura, Toshiyuki Yamamoto, Toshio Yoshii and Tomio Miwa

Proceedings of the 10th World Congress on Intelligent Transport Systems, November 16-20, 2003, Madrid, Spain 2003

Language：English

The relationship between the travel speed at the main road and that detouring through neighborhood streets is examined by using the probe car information. The results suggest that the two travel speeds are positively correlated, implying that more drivers detour from the main road to the neighborhood street when the congestion at the former is severer. The results also show that the travel speed through the neighborhood streets has considerable variances regardless of the travel speed at the main road.

A methodology for weighting data from complex endogenous sampling Reviewed

Kitamura, R., Yamamoto, T. and Sakai, H.

Transportation Research Part B Vol. 37 ( 4 ) page： 387-401 2003

Language：English Publishing type：Research paper (scientific journal)

The methodology for weighting endogenous samples is extended in this study and applied to a multi-dimensional choice-based sample and an enriched sample. It is shown that a unified weight exists for a sample obtained from a complex endogenous sampling scheme. Problems with conventional weighting methods for samples from endogenous sampling, such as roadside surveys, are pointed out and an improved weighting scheme is proposed. Coefficient estimates of discrete choice models with and without weights are compared, and the importance of applying appropriate weights and a valid covariance estimator is pointed out.

The effectiveness of panels in detecting changes in discrete behavior Reviewed

Kitamura, R., Yamamoto, T. and Fujii, S.

Transportation Research Part B Vol. 37 ( 2 ) page： 191-206 2003

Language：English Publishing type：Research paper (scientific journal)

This study addresses the issue of how accurately parameters characterizing a stochastic, discrete behavioral process can be estimated using data from a discrete-time panel study. Specifically, the study examines the likelihood and magnitude of error in estimating the parameters characterizing the behavioral process based on observations of the process obtained at discrete time points. The results of the study offer strong indications that the likelihood and magnitude of error can be both very large. Furthermore, reducing the interval between survey waves improves estimation accuracy but only very slowly. The study results point to the need to obtain continuous data as accurately as possible from surveys made at discrete time points, using carefully designed and administered recall questions.

On the Formulation of Time-Space Prisms to Model Constraints on Personal Activity-Travel Engagement Reviewed

Ram M. Pendyala, Toshiyuki Yamamoto and Ryuichi Kitamura

Transportation Vol. 29 ( 1 ) page： 73-94 2002

Language：English Publishing type：Research paper (scientific journal)

The notion of time-space prisms has often been used in the context of describing activity-travel patterns of individuals. This paper presents a methodology for estimating the temporal vertices of time-space prisms using the stochastic frontier modeling technique. Observed trip starting and ending times are used as dependent variables and socio-economic characteristics and commute characteristics serve as independent variables. The models are found to offer plausible results indicating that temporal vertices of time-space prisms, though unobservable, can be estimated based on temporal characteristics of observed activity-travel patterns. Comparisons of stochastic frontier models of prism vertices and the distribution of prism vertices are presented using two activity data sets collected in the United States – San Francisco and Miami. Differences and similarities in temporal vertex locations are highlighted in the paper.

Comparison of non-compensatory models of driver's choice on dynamic park and ride Reviewed

Toshiyuki Yamamoto, Shinya Kurauchi and Takayuki Morikawa

Proceedings of the 9th World Congress on Intelligent Transport Systems (CD-ROM) 2002

Authorship：Lead author Language：English Publishing type：Research paper (scientific journal)

Non-compensatory models of driver's choice on dynamic park and ride are developed and examined on the predictability in this study. One of the data mining tools, C4.5, is used to develop decision tree and production rules of driver's choice. The generated decision tree and production rules are compared with the semi-ordered lexicographic model developed in the preceding study. Compared are the similarity of the estimated decision making structures and the distribution of the segments not correctly represented by the models as well as goodness-of-fit and hit ratio. The comparison shows that the semi-ordered lexicographic model has a higher goodness-of-fit and hit ratio than models with data mining tools. The results also suggest that the models developed in this study represent different decision rules from, but have similar distributions of the segments not represented by the models with the semi-ordered lexicographic model. Empirically, the consistent results by models with data mining tools and the semi-ordered lexicographic model suggest that the parking congestion level in CBD has a significant effect on the choice behavior.
