Yetkin, Raife Meltem
The aim of this study is planning the locations of emergency centers (ECs) as well as the number of vehicles in each EC of Corporation, Man Truck and Bus Group, to respond to the calls (arrival of the mobile/24 emergency service vehicle to the broken vehicle) within the desired time. The company aims to respondto the calls within 90 minutes. If the EC cannot respond to the calls within 90 minutes, they should be satisfiedwithin 180 minutes. We propose a probabilistic programming approach to maximize the number of responded calls in 90 minutes while responding to all the calls in 180 minutes. The model determines the locations of the new ECs addition to the existing ones and also the number of vehicles assigned to those centers. The data source to this study is the emergency service calls of the company within February 2008 and December 2010. There are 30 ECs of the company distributed all over Turkey. By using the data, it is examined if the company can get closer to its target in responding to the calls with the current ECs. Necessary changes are proposed in the number and the locations of emergency centers for the desired target. Furthermore, several scenarios for targets with different quality service levels are generated and the effects of these parameters on the objective are observed.

Location analysis of emergency vehicles using an approximate queueing model
Akdoğan, Muharrem Altan; Bayındır, Zeynep Pelin; İyigün, Cem (Elsevier BV; 2016-09-07)
In this study, location analysis of emergency system vehicles is discussed using an approximate queueing model (AQM) on fully connected networks. We relax single vehicle restriction in each vehicle location which is commonly employed in the literature. Order of districting structure is used to transition rates in AQM. Service rates are computed regarding the location of the demand call and the vehicle, which provides higher resolution than inter-intra district service rates. Generic rate formulations are de...
Tracking Reported Vehicles in Traffic Management and Information System using Intelligent Junctions
Elci, Atilla; RAHNAMA, BEHNAM; Amintabar, Amirhasan (2010-05-01)
This study highlights a security scenario involving vehicles in a Traffic Management and Information System (TMIS) network. TMIS and its nodal architecture, nicknamed Intelligent Junction (IJ), are summarized from our recent work. System design sets an example to a software architecture implementing autonomous semantic agents through semantic web services, junction-based sensor networks, local- and wide-area networking through wire/wireless integrated communication infrastructure. It is so construed as to p...
Mobility-on-demand scenarios relying on lightweight autonomous and connected vehicles for large pedestrian areas and intermodal hubs
Kumru, Murat; Makarem, Laleh; Gillet, Dens (null; 2017-10-05)
This paper presents Mobility-On-Demand (MoD) scenarios relying on lightweight autonomous and connected vehicles to ease commuting in large pedestrian areas and intermodal hubs. In particular, we discuss the case of the EPFL campus as an example of a large pedestrian area and the case of the main Zurich train station as an example of a large intermodal hub. These two scenarios help to investigate the potential benefits and the implementation challenges of innovative lightweight autonomous and connected vehic...
Telegram Scheduling for the Multifunction Vehicle Bus (MVB): Algorithms and Evaluation
Çaǧlar Güldiken, Mustafa; Schmidt, Şenan Ece; Schmidt, Klaus Verner (2020-07-01)
© 2020 IEEE.Multifunction Vehicle Bus (MVB) is a highly robust real-time field bus for rail vehicles. On MVB, periodic process data and sporadic message data are transmitted in the form of telegrams. The main focus of this paper is the development of heuristic scheduling algorithms for periodic telegrams on MVB. We first propose two heuristics that find the best location of individual telegrams in the MVB schedule based on different criteria. Then, we introduce a new swap operation that allows improving MVB...
Secure message authentication protocol for can (controller area network).
Mertol, Sarp; Doğanaksoy, Ali; Department of Cryptography (2020)
The widespread communication of vehicles with each other and road infrastructure has raised concerns about how to ensure network security of the electronic control units (ECUs) in the vehicle. The fact that networks such as the Controller Area Network (CAN), which is commonly used in in-vehicle communications, will also be connected to external networks (e.g. 3G / 4G mobile networks) will allow malicious adversaries to benefit from the vulnerability of the CAN. The authentication of messages of ECUs in the ...
