Abstract: This paper explores the interrelationship between trip chain pattern and trip mode choice based on multinomial logistic model, using 2010 Nanjing resident trip survey data. Unlike previous literatures, trip mode choice is divided into single-mode and multi-modes in this study. Estimation coefficients verify trip chain pattern and trip mode selection are a pair of choices that influence each other. Trip mode is great positively associated with trip chain pattern of HW+WH, HO+OH, HW+OH, however, in return trip chain pattern is the most significant negative factor that affects trip mode choice, which means that no trip chain pattern would provoke travelers to select multi-modes. Despite the results seem to reach a contradiction between trip chain pattern and trip mode choice, still two facets of views try to explain the phenomenon, in addition, discussion on the interrelationship between complex trip chain pattern and multi-modes which might put forward more challenges to urban planning is also proposed as well in the paper.

Abstract: This study reviews the current status of the understanding and development of laser shock peening(LSP) on various metals. The influence of processing parameters on residual stresses, microstructure and properties are discussed. Special emphasis is placed on analyzing their underlying interrelationship between the LSP induced modifications. Finally, recommendations for further study are listed. Results indicate that the combination of uniquely flexible process and excellent performance makes the laser shock peening an attractive candidate for surface optimization applications.
