We study a queueing system with Poisson arrivals on a bus line indexed by integers. The buses move at constant speed to the right and the time of service per customer getting on the bus is fixed. The customers arriving at station i wait for a bus if this latter is less than di stations before, where di is non-decreasing. We determine the asymptotic behavior of a single bus and when two buses ev...

Most airports have two types of gates: gates with an air bridge to the terminal and remote stands. For flights at a remote stand, passengers are transported to and from the aircraft by platform buses. In this paper we investigate the problem of planning platform buses as it appears at Amsterdam Airport Schiphol. We focus on robust planning, i.e., we want to avoid that the bus planning is affect...

This paper proposes a flexible approach to bus media redundancy in Controller Area Network (CAN) fieldbuses, both to improve the bandwidth by transmitting different traffic in different channels or to promote redundancy by transmitting the same message in more than one channel. Specifically the proposed solution is discussed in the context of Flexible Time-Triggered protocol over CAN (FTTCAN) a...

The aim of this article is to explore the linkage of two microsimulators developed at the University College London. At present, these models deal independently with buses at either bus stops or traffic networks. First, both microsimulators are described in some detail. The generic way in which both models can be connected is then proposed. As a result of this analysis, the main issues for a co...

In this paper, new voltage sensitivity indexes are proposed to search and evaluate the candidate buses in a microgrid, where the energy storage systems can be installed to contribute most effectively to the system. These indexes are derived from the inverse Jacobian matrix from the NewtonRaphson power flow analysis. After calculating and evaluating these indexes for the studied microgrid, four ...

The primary challenge for an urban bus system is to maintain constant headways between successive buses. Most bus systems try to achieve this by adherence to a schedule; but this is undermined by the tendency of headways to collapse, so that buses travel in bunches. To counter this, we propose a new method of coördinating buses. Our method abandons the idea of a schedule and even any a priori t...

Recently, bus transit operators have begun to adopt technologies that enable bus locations to be tracked from a central location in real-time. Combined with other technologies, such as automated passenger counting and wireless communication, it is now feasible for these operators to execute a variety of real-time strategies for coordinating the movement of buses along their routes. This paper c...

The development of surface public transportation networks is a major issue in terms of ecology, economy and society. Their quality in term of punctuality and passengers services (regularity between buses) should be improved in order to improve their attractiveness. To do so, cities often use regulation systems at intersections that grant priority to buses. The problem is that each transportatio...

Most automotive applications today consist of a set of interacting tasks. These applications are implemented on a distributed architecture consisting of several ECUs connected by buses. Although algorithms are designer to be robust, several communication flows between tasks should be designed in such a way that there is no loss of data. Furthermore, safety critical applications depend on correc...

A number of field buses are available to exchange the serial data among one or more controllers and a number of field devices that are communicating with each other. However, field bus standards are not uniform at present, which brings many difficulties in system design, as different equipments from different manufacturers follow different standards. For a reliable system design there is a need...
