Mathematical models for traffic observation and prediction and design and probabilistic safety analysis of railway lines

ABSTRACT: This thesis consists of two main parts. The first one is devoted to traffic problems, that (a) include a state-of-the-art review of the sensor location, flow observability, estimation and prediction problems in traffic networks and (b) present new methods for the optimization of link obser...

Sumario:ABSTRACT: This thesis consists of two main parts. The first one is devoted to traffic problems, that (a) include a state-of-the-art review of the sensor location, flow observability, estimation and prediction problems in traffic networks and (b) present new methods for the optimization of link observability based on linearly independent paths. The second part deals with some railway problems, including: (a) the alternate double-single track proposal (ADST) for high speed peripheral railway lines, which optimizes the construction investment and (b) a new method for probabilistic safety analysis (PSA) of railway lines based on Bayesian networks to assess safety level of any line, and to detect their critical points. It is worth to indicate that two software have been developed to study of ADST and PSA analysis.
