Comparative Analysis on Complexities of Macroscopic Transportation System between China and Japan
Fengtao Liu, Haisheng Cao, Yong Liu · 2009
How to measure the complexity of transportation system is a hotspot in the transportation study. The Lempel-Ziv algorithm of information theory was introduced to investigate the measure problem of transportation system complexity. Aiming at the misapplication of this algorithm, the universal algorithm of trial and error was proposed. Twenty time series, representing Chinese and Japanese different subsystems, whose complexities and prediction errors were calculated by Lempel-Ziv measuring and ARIMA modeling, respectively. The conclusions are as follows: the complexity of macroscopical transportation system is low and the macroscopical transportation system is predictable; predictability is negatively correlated with complexity.
