The aim of this work is to present Real-Time Driver Advisory System (RTDAS) for improving energy economy of Electric Vehicles (EV) and Hybrid Electric Vehicles (HEV). System relies on a road map data provided in accordance with the second version of Advance Driver Assistant Systems Interface Specification (ADASIS v2) Protocol. Road map data is then transformed into Electronic Horizon (EH). The Electronic Horizon provides a preview of the road characteristics ahead of the vehicle, which is used for development of a predictive energy economy algorithms. The system is focused on static characteristics of the road ahead such as road slope, curvature, superelevation, speed limits and the traffic signs. Based on this data and vehicle parameters, the system is using algorithms to define if and when to send a message to the driver to release the gas pedal and to achieve higher energy economy, comfort and safety of driving. The releasing of gas pedal triggers an algorithm to adjust the speed using controlled regenerative braking without using mechanical brakes that leads to optimization of vehicle kinetic energy recuperation.

The driver behavior is a complex problem of the road traffic safety. It is influenced by numerous factors. Drowsiness, fatigue, health issues, influence of alcohol, irritated or aggressive behavior , arrogance etc. - all contribute to dangerous behavior of drivers on the roads and lead to traffic excesses. Driver faults happen all the time, so their prevention and mitigation of unwanted consequences is a necessary step in improving road traffic safety. The book covers analysis of different aspects of dangerous driving behavior, from drivers' faults due to lack of experience, the influence of drugs (in a general sense), driver's age etc., up to intentional offensive and aggressive driving.

This paper provides the assessment of in-vehicle information system of virtual traffic lights. The measurements on steady simulator, based on a cockpit of personal car, were obtained for two groups of drivers (either with or without assistance device provided). During the experiment on a simulator the driver behavior was investigated with a help of head mounted eye-tracking device (focus and eye behavior was analyzed) and video camera. The driver performance was analyzed from simulator outputs (based on analyses of actual speed, lane keeping and lane position, brake pedal depression and derived reaction times) and appropriate reactions to scenario events and situations (following directions given by traffic signs). Technical data of drivers’ performance - following traffic sign instructions, the reasons in case of not following those in real road situations as well as driver acceptance of the system collected during surveys are analyzed.

This paper studies a possibility to use a set of onboard high-resolution cameras and GPS unit to detect aggressive drivers near a floating car in real traffic. Hardware and software requirements and system architecture are described in detail. Different types of classifiers and object tracking algorithms are described and compared. Mainly open source software packages, such as OpenCV with GNU license, are considered due to the possibility to use them in projects without any restrictions and adjust a source code to specific needs. Additionally we describe a possibility to increase quality of GPS positioning with information obtained from a CAN bus of the vehicle. Information about vehicle speed, steering angle etc. are used to construct a physical model of the vehicle, real GPS coordinates and position obtained by a model are further fused by Kalman filter. At the same time, GIS data and information from onboard cameras are used to obtain in lane position of the vehicle.

The book deals with possibilities how to reduce risk of a road and rail vehicle collision on level crossings. There are several reasons making the solution of this matter urgent nowadays. One of the reasons is the increase in traffic intensity and rising cruising speed of cars. As well the rising railway traffic, mainly caused by regional and local lines in the urban areas, calls for higher cruising speeds of trains. Such elements can increase the coincidence of factors leading, under unfavorable circumstances, to fatal effects mostly for road users. The book presents historical view on R-R level crossing safeguard and its development mainly within the Central Europe area, worldwide activities which should lead to safer situation at level crossings, recommendations for safer design and risk analysis and finally the lessons learn from the real pilot project realized in the scope of national grant which members the book authors were.
