Summer extreme heat threatens the health of individuals, especially persons who are involved in outdoor activities. Ensuring the normal function of a city, bus drivers are among those who participate in outdoor physical activities and are exposed to excessive heat in hot summer weather. This qualitative study was performed to explore professional bus drivers' in-depth views of extreme heat risk...

Dieses Paper stellt eine Methode zur Absicherung der Basissoftware von AUTOSAR Steuergeräten vor. Dabei wird die Basissoftware auf die Funktionalität getestet, die sie für die Kundenfunktionalität, also die Applikationsschicht, zur Verfügung stellen muss. Der Test wird im Steuergerät durch ein Complex-Device-Driver-Modul durchgeführt. Ein externer Tester steuert automatisiert das Complex-Device...

The development of mobile IT continuously provides new resources of use in the road environment. However, there are problems turning technical options into meaningful applications. This paper presents a method where observation of daily practices to identify users' demands to inform ITS-design. The particular case is bus driving and public transport management, seen from the bus-drivers’ perspe...

Bus drivers often have irregular working hours like split shifts and their work involve high levels of stress. These factors can lead to severe sleepiness and dangerous driving. The purpose of this study is to highlight how split shifts affect sleepiness and performance during afternoon drive. The study is an experiment on real road with an equipped bus driven by professional bus drivers. The s...

A high-speed memory bus interface which enables greater throughput for data reads and writes is described in this paper. Current mode CMOS logic synthesis methods are used to implement multi-valued logic (MVL) functions to create a high bandwidth bus. First, a fundamental bi-directional data bus for multiple logic levels is presented. Then a bi-directional data bus with impedance matching termi...

Research in bus and driver scheduling at Leeds University has been taking advantage of new technologies since the early 1960s, with the objective of yielding better schedules more quickly. Here recent SERC supported work is presented. Most bus scheduling systems produce schedules for only one operating scenario. In practice, planning and scheduling are interconnected, and operators have to expl...

The paper presents a methodology to integrate information on power consumption in a high level functional description of a System-on-chip. The power dissipated during the execution of each system level instruction, stored in a Look-up Table, is used in a System level simulation. The methodology has been applied to the design of an IC bus driver

The Navlab group at Carnegie Mellon University has a long history of development of automated vehicles and intelligent systems for driver assistance. The earlier work of the group concentrated on road following, cross-country driving, and obstacle detection. The new focus is on short-range sensing, to look all around the vehicle for safe driving. The current system uses video sensing, laser ran...

A series hybrid city bus with diesel engine and electric batteries is studied on a specified route. The study uses two different basic control strategies, " On/off " and " Continuous " strategy. These basic strategies are complemented in two ways. First, an " Adviser " strategy which filters the driver commands and gives driver support feedback based on the route data. Second, an " Adapter " st...
