The last decade has witnessed the introduction of several driver assistance and active safety systems in modern vehicles. Considering only systems that depend on computer vision, several independent applications have emerged such as lane tracking, road/traffic sign recognition, and pedestrian/vehicle detection. Although these methods can assist the driver for lane keeping, navigation, and colli...

Bus bunching is an instability problem where buses operating on high-frequency public transport lines arrive at stops in bunches. This work unveils that bus-following models can be used to design bus-to-bus cooperative control strategies and mitigate bunching. The use of avoids the explicit modelling bus-stops, which would render resulting discrete, with events occurring arbitrary time interval...

OBJECTIVE Between November 1994 and April 1995, more than 3300 students in 49 schools in two counties in New York were potentially exposed to five school bus drivers with tuberculosis. This investigation was carried out to determine the extent of transmission of Mycobacterium tuberculosis among students. METHODS Components of the epidemiologic investigation included tuberculin skin-test scree...

The Bus Driver Rostering Problem (DRP) consists of assigning bus drivers to daily duties during a planning period. The problem considers hard constraints imposed by institutional and legal requirements. Solutions should as much as possible satisfy soft constraints that qualify rosters according to either the company’s or the drivers’ interests. A bi-objective version of the DRP is considered an...

This paper presents the implementation of a Linux-based experimental boundary scan environment. Its primary aim is to provide a ¯exible and completely open platform to people interested in experimenting with IEEE 1149.x and related standards and allow them to develop custom applications requiring boundary scan infrastructure control capabilities. The experimental boundary scan test platform is ...

A study was conducted to investigate the effects of time-gap settings and contents of secondary tasks on a fix-based bus driving simulator on drivers’ performance while reclaiming control from ACC in a car-following scenario of emergency brake by the lead vehicle. Thirty professional bus drivers drove on the simulator with the scenario of highway traffic flow under 12 random time-gap settings: ...

This study reports the results of a simulator-based assessment of driver response to two different urban highway work zone configurations. One configuration represented an existing design which was contrasted with a second configuration that presented a reduced taper length prototype work zone design. Twenty-one drivers navigated the two different work zones in two different conditions, one wit...

Microprocessors with built-in Liquid Crystal Device (LCD) controllers and equipped with Flash ROM are common in mobile computing applications. In the first part of the paper, a software-only encoding technique is proposed to reduce the power consumption of the processor-memory bus when displaying an image on the LCD. Based on the translation mechanism of the LCD controller, the approach of this...

The desire to enhance the attractiveness of public transit services constitutes a factor of development as well as innovation in this field. Such a motivation is typically aimed at improving the performance of systems while holding costs under control. Against this backdrop, we have analyzed a docking assistance device installed on conventional articulated buses and placed into operation in two...

Psychosocial risk factors have been considered as characteristics of the work environment rather than an individual issue, but their presence in the workplace is usually measured by self-reported questionnaires, based on worker attitudes. The objective of the study was to compare a self-reported measure of psychological job demands in a bus driver sample with selected indicators of bus company ...
