A Generic and extendable system architecture for intelligent transportation systems /

Çetinkaya, Kaan
Intelligent Transportation Systems (ITS) are distributed systems with different communicating parties which are vehicles with ITS-supporting On Board Units (OBUs), Road Side Units (RSU) and user mobile devices. These parties collectively run application services that are developed and managed by different application service providers by communicating among each other under certain timing constraints. In the current state of art, hardware, software and communications that are required to implement a given ITS application are all specifically re-designed for each application service. This thesis presents a system architecture named as Car Content Delivery (CarCoDe) for ITS application development complete with a software stack and communication specifications. CarCoDe is generic and can be used by all ITS parties by defining the relevant specific features. It provides a simple software stack and supports both short range and long range communications over a third node. Furthermore, CarCoDe has been attached with great importance to flexibility and modularity features which make it extendable for future contributions. The features of CarCode are demonstrated by a realization of it for a vehicle OBU and implementing an icy road warning application.


An End-to-end communication architecture for intelligent transportation systems: design, implementation and latency analysis
Bağcı, Çağatay; Schmidt, Şenan Ece; Department of Electrical and Electronics Engineering (2018)
Vehicle to anything (V2X) communication is a very significant component of Intelligent Transport Systems (ITS) applications. This thesis proposes an application layer communication architecture, ITSVeCon for V2X communications which enables communication among the end-hosts which can be vehicle Electronic Control Units (ECU)’s, Road Side Units (RSU)s, computers, smart phones or third party service providers. All these end-hosts are bi-directionally connected to the ITSVeCon Server where this server carries ...
An algorithm for multiscale license plate detection and rule-based character segmentation
Karalı, Ali Onur; Ulusoy, İlkay; Department of Electrical and Electronics Engineering (2011)
License plate recognition (LPR) technology has great importance for the development of Intelligent Transportation Systems by automatically identifying the vehicles using image processing and pattern recognition techniques. Conventional LPR systems consist of license plate detection (LPD), character segmentation (CS) and character recognition (CR) steps. Successful detection of license plate and character locations have vital role for proper LPR. Most LPD and CS techniques in the literature assume fixed dist...
An algorithm for the capacitated vehicle routing problem with time windows
Pehlivanoğlu, Osman; Meral, Fatma Sedef; Department of Industrial Engineering (2005)
In this thesis the capacitated vehicle routing problem with time windows (VRPTW) is studied, where the objective is to serve a set of geographically dispersed customers with known demands and predefined time windows at the minimum cost. It is hard to find an optimal solution for the VRPTW even if the problem size is small. Therefore, many heuristic methods are developed to obtain near optimal solutions. In this study a local search algorithm is proposed for solving the VRPTW, which consist of route construc...
A communication architecture for Intelligent Transportation Applications
Bağcı, Çağatay; Schmidt, Şenan Ece (2017-06-29)
This paper proposes ITCON (ITS CONnectivity) which is based on communication of the end systems running Intelligent Transportation Applications over a remote server that. performs application level switching. ITCON provides seamless connectivity for different types of devices using WebSocket structures. ITCON is implemented for vehicle to vehicle applications that access the IP Core networks over cellular mobile networks. Detailed timing performance evaluations are presented.
An Adaptive Approach for Road Boundary Detection Using 2D LIDAR Sensor
Demir, S. O.; Ertop, T. E.; Koku, Ahmet Buğra; Konukseven, Erhan İlhan (2017-11-18)
Robotic ground vehicles are commonly used in various road conditions for performing special tasks with different levels of autonomy. This requires the robots to possess a certain degree of perception about the road conditions up ahead and make plans accordingly. It is essential for the robots to be able to quickly adapt their perception for various road conditions they operate. In this paper, an adaptive method for road boundary extraction using 2D LIDAR sensor is presented. A three-stage detection algorith...
