Liu, Zhigang (author), Wang, H. (author), Dollevoet, R.P.B.J. (author), Yang, S. (author), Nunez, Alfredo (author), Zhang, J. (author)This paper explores the use of pantograph-catenary contact force (PCCF) for monitoring of the current collection quality and detection of anomalies in the interaction between pantograph and catenary. The concept of catenary structure wavelength (CSW) is proposed as the dominant component of PCCF. It describes the signal components caused by the...journal article 2016

Zheng, Fangfang (author), Li, Jie (author), van Zuylen, H.J. (author), Liu, Xiaobo (author), Yang, Hongtai (author)The decision making of travelers for route choice and departure time choice depends on the expected travel time and its reliability. A common understanding of reliability is that it is related to several statistical properties of the travel time distribution, especially to the standard deviation of the travel time and also to the skewness....journal article 2017
