Due to its environmentally sustainable and energy-saving characteristics, railway transportation nowadays plays a fundamental role in delivering passengers and goods. Emerged in the area of transportation planning, the crew (workforce) sizing problem and the crew scheduling problem have been attached great importance by the railway industry and the scientific community. In this paper, we aim to...

New infrastructure-less traffic collision avoidance systems are currently developed for road and railway transportation. Similar to maritime and air transport a significant increase in safety is expected by exploiting direct vehicle-to-vehicle communication to detect possible collision threats and to immediately warn the driver. Augmented cognition is a key feature to expand the driver’s “view”...

Short-term passenger flow forecasting is an important component of transportation systems. The forecasting result can be applied to support transportation system operation and management such as operation planning and revenue management. In this paper, a divide-and-conquer method based on neural network and origin-destination (OD) matrix estimation is developed to forecast the short-term passen...
