Abstract: In this paper, model predictive control of traffic networks using first-order macroscopic link transmission model (LTM) is considered. The LTM model provides fast yet accurate predictions for traffic networks compared to other models. In order to use this model for traffic control, it is extended to include ramp metering. Using the extended LTM model as prediction model in a model predictive control framework, one can determine optimal control signals for metered on-ramps. However, the optimization problem is still nonlinear and nonconvex, and in general it is not tractable to find its global optimimum, as global or multi-start local optimization techniques take considerable time. Therefore, in this paper the extended LTM model is transformed into a mixed logical dynamic model. The resulting optimization problem can be recast as a mixed integer linear program (MILP) that can be solved much more efficiently than the nonlinear optimization problem, and it allows to determine a global optimum efficiently. A simple case study is selected, first to test the modeling performance of the extended LTM and next to compare the control performance of the MILP approach and the original nonlinear formulation in terms of computational efficiency and total cost.

Abstract: In the present article we offer a method for the highway traffic flow modeling, based on the Green function as a trans¬formation tool. This approach is suitable for distributed parameter systems in order to re¬formulate their partial differential equation description as sets of transfer functions. The model used in our work is the macroscopic continuous Lighthill-Whitham-Richards representation. The physical phenomena characteristic for the vehicular flow on a highway section are analyzed over some important length. This im¬plies the description of the traffic as a distributed parameter plant. We present the Green func¬tion transforma¬tion’s general case and after we apply it to the considered traffic flow model in order to obtain its transfer func¬tion form. The sets of expressions obtained can be specified using concrete fundamental diagrams and data, and also can be im¬plemented in the design of control strategies.

Abstract: Over the recent years Dynamic Traffic Assignment (DTA) models are commonly used for the online and offline optimization of traffic control strategies in complex urban environments. The stability of the Dynamic Traffic Assignment is crucial for achieving the best possible representation of traffic phenomena in congested urban networks, where through the progress of time, the increase of traffic congestion reduces the network efficiency. In this paper we investigate the stability analysis of a DTA procedure through the notion of network efficiency. Numerical results of a sensitivity analysis of the interval size for two test networks show the correlation between the stability of the DTA, the time-dependent efficiency of the network and the interval size of the DTA procedure.

Abstract: Reliability is defined as “ability of an item to perform a required function under given conditions for a given period of time” in CENELEC (European Committee for Electrotechnical Standardization) EN 50128 document where software development requirements for railway applications are defined. Similarly, Software Reliability is defined as the probability of failure-free software operation for a specified period of time in a specified environment which is also important factor affecting system reliability (Pan, 2012). Systems such as railway signalization systems, where small errors can result in fatal accidents and death of several people or possibility of unwanted risks (like component malfunction) is high, also need software with high reliability. In this study, some parts of the safety-critical interlocking software development process for the Turkish National Railway Signalization Project (TNRSP) executed in cooperation with Istanbul Technical University (ITU) and The Scientific and Technological Research Council of Turkey (TUBITAK) for Turkish State Railways is defined.

Abstract: Interlocking is the most important component of a signalization system, which ensures safe travel and transportation. An interlocking system helps movement of trains on desired routes in fixed block signaling systems. The first step in the design of interlocking systems is to generate interlocking tables. Generation of interlocking tables for small scaled stations or railway yards can be realized easily. However, when the topology of the station is complicated, generation of the corresponding interlocking table becomes considerably difficult. In this study, a program that automatically generates interlocking tables for a given railway yard is explained. One of the main advantages of the program is that, switches and signal lights are placed automatically for a given station or railway yard depending on the topology.

Abstract: The main issue in controlling safety-critical systems such as nuclear power reactors or railway signalization systems where risk ratio is at the highest level because small errors might result in hazardous accidents (e.g. death or injury of several people) is to satisfy safety-related standards and provide high-safety with high-reliability. In order to improve reliability and safety of such systems to the required level by decreasing common-cause failures at the same time, diverse programming (or N-version programming) technique where N-different independently designed modules run in parallel on the same input output specifications can be used. In this study, a new bitwise voting strategy based on safe-states of variables is proposed and possible critical races between modules those run in a parallel manner are determined. Solutions for critical races are also explained.

Abstract: Interlocking systems are one of the most important elements of railway signalization systems in order to ensure safe transportation. Software design of the interlocking systems can be performed by different methods such as automaton method, petri nets. These systems can be implemented by mechanical components or electronic devices such as Programmable Logic Controllers (PLCs). In this study, an interlocking system is designed by using automaton method for a sample railway simulator so that trains can move in a safe manner. In addition, in order to provide complete automatic operation, another system is also designed. Then both designed interlocking and automatic operation systems are implemented in Beckhoff CX1010 PLC and tested on simulator with the help of human interface that is created for this purpose.

Abstract: An important problem in traffic estimation, forecasting, and control is the reconstruction of densities in portions of the road links not equipped with sensors. In this paper, and based on ideas from Morarescu and Canudas-de Wit [2011], we use a deterministic constrained model that reduces the number of possible affine dynamics of the system and preserves the number of vehicles in the network. In particular we formulate the idea in Morarescu and Canudas-de Wit [2011] with the correct number of feasible modes, and introduce the concept of graph constrained-CTM observer, which is used to reconstruct the densities from the Grenoble south ring use case that contains 45 cells organized in 9 links, and is simulated using a calibrated AISUM micro-simulator. This work is performed in connection with HYCON2 traffic show case (www.hycon2.eu), and with the Grenoble Traffic Lab (GTL) (http://necs.inrialpes.fr/pages/reseach/gtl.php)

Abstract: The goal of this paper is to describe TIMIPlan, an application that solves the multi-modal and uni-modal transportation problems of one of the largest Spanish transportation companies. The first problem, related to multi-modal transportation, reflects the combination of at least two modes of transport in a single transport chain, without change of container for the goods. In this paper we describe a hybrid algorithm, combining Linear Programming and Automated Planning, to tackle the multi-modal transportation problem exploiting the benefits of both kinds of techniques. The second problem refers to a common uni-modal transportation problem: the delivering of goods from a central depot to consumers with time windows, and where only the road transport mode is used. This is the well-known Vehicle Routing Transportation Problem with Time Windows (VRTPTW). In this paper we describe an ant colony optimization approach used to solve the VRTPTW.

Abstract: The overexposure of drivers to congested traffic and/or non-recurrent incidents (such as accidents or adverse weather) significantly affects their driving style. Hysteretic phenomena in the macroscopic fundamental traffic diagram have been linked to aggressive and timid driving. We analyze hysteresis through vehicle trajectories on both a macroscopic and a microscopic level in order to reveal the features of different driving styles in the occurrence of congested conditions. Instances of traffic hysteresis are detected and categorized according to the driver behavior they reflect. Then, their macroscopic and microscopic traffic flow characteristics are estimated and statistically investigated using artificial neural networks. Analysis reveals that changes in spacing and acceleration at the end of the phenomenon appear to be the most critical determinants of driver behavior. Different determinants of hysteresis for aggressive, as well as timid drivers are investigated, quantified and compared.

Abstract: This paper proposes an efficient solution approach for the line balancing problem in state-of-the-art baggage handling systems that are based on destination coded vehicles that transport the bags from their origins to their destinations. First, a simple event-driven model of the process is presented. Next, this model is applied within the context of model predictive control to determine the optimal number of destination coded vehicles to be dispatched from the central depot to each loading station. The performance criterion is minimizing the overall baggage waiting time as well as the energy consumption.

Abstract: This paper presents a signal control method of urban road traffic by using model predictive control (MPC), where online adjustments of all free parameters of traffic signals, i.e., cycle times, split times and offsets, are focused on simultaneously. A simple model of macroscopic traffic, whose dynamics are nonlinear involving binary representation corresponding to green and red signals, is formulated. The parameters of the model are calibrated by using data obtained from detailed microscopic simulation that yields realistic statistics. The simple model is transformed into a mixed logical dynamical system (MLDS), and a mixed integer optimization is applied in the MPC framework. The proposed control scheme makes the signals flexibly turn to red and green depending on traffic conditions in the road network. By adapting quickly to any changes in traffic conditions, the scheme generates appropriate traffic signals, and the traffic flow is kept optimum regardless of such changes. Results of optimization are also verified by microscopic traffic simulation using a detailed model. It is demonstrated that the proposed control scheme reduces the average number of vehicles and their average stay time in the network by outperforming other ones that control only the frequency and the phase of each traffic signal.

Abstract: A bi-level optimization problem is defined for controlling an arterial corridor of a traffic network. The hierarchical relations between two optimization problems allow optimizing two types of control variables: the split of green duration and the cycle time of the traffic lights. The benefit of the bi-level formulation has been identified and assessed.

Abstract: A game-theoretical method is proposed to achieve a system-optimal distribution of traffic over a freeway network. In particular, the road authority is represented by a leader player and each follower player embodies a group of drivers with the same value of time that plan to travel between a given origin and destination. In the proposed reverse Stackelberg approach, the leader presents a function to each follower that maps a vector of splitting rates over possibles routes to a monetary incentive. The follower then decides upon a splitting rate and the associated monetary incentive that yield the minimum weighted measure of travel time and monetary fees. In this manner, the road authority can compose an optimal leader function under which the followers will behave as desired, i.e., to achieve the system-optimal splitting rates.

Abstract: This paper deals with the modeling and the identification of an electromechanical Diesel engine actuator. The SAIA-Burgess actuator, studied in this work, is in charge of the control of the coolant flow passing through an exhaust gas recirculation (EGR) cooler. This study aims to design a complete simulator that accurately predicts the actuator dynamics taking into account the effects of friction phenomenon. An overview of the actuator structure and its operation principle is first given. Then, its mathematical model as well as the nonlinearity, related to its behavior, are generally discussed. A step-by-step identification procedure is subsequently introduced allowing the estimation of both the system parameters and the friction model coefficients. Finally, Simulation results, using Matlab-Simulink, and experimental results, using LabVIEW and CompactRIO, are presented showing that the developed simulator is able to accurately reproduce the actuator dynamics.

Authors: Acarman, Tankut
Abstract: In this paper, a multimodal adaptive driver assistance system is studied on a simulator setup. The main goal is to determine human driver's attention and authority level in a cognitive model and to trigger timely warnings according to his/her driving intents and driving skills with respect to the possible driving situation and hazard scenarios. In the previous studies, a fairly restrictive vision-based driver assistance system has been deployed to detect lane departure, blind-spot and to monitor following distance, headway time. The presented system models driving task in a cognitive architecture and assesses the cognition of the human driver by modeling the situation awareness of the driver by using fuzzy sets. Each fuzzy set simply represents the expert driver's perception in both of the longitudinal and lateral traffic. The presented system evaluates the driver's driving skills and attention level by comparing the expert and human driver's reactions suited in a finite set of decision and maneuvering task. In case of hazard analysis, the system triggers timely warnings pointing the driver's attention at the lateral or longitudinal maneuvering tasks depending on the interpreted situation. Introductory experiments are performed with a limited number of participants, the test driving data including the driver's perception and reaction to the surrounding vehicles and traffic situations are collected by the use of vehicle simulator. And the presented multimodal adaptive driver assistance system is evaluated by the simulator. The preliminary results seem to be promising.

Abstract: A planning method for traffic management and control is developed in this paper based on Hierarchical Task Network (HTN) planning technology. This method overcomes some weaknesses of goal-oriented algorithm Traffic Problem Solver (TPS) that is applied in the knowledge-based agent called Traffic Congestion Manager (TCM) to deal with real-time traffic congestion problems. Based on the domain knowledge, such as the definition of control actions, extracted from TCM, a domain model with domain description and problem description is built and tested by JSHOP2. The test result shows that, compared with TPS, the HTN planning method can provide a better system performance when dealing with large-scale problems, and have a great potential to deal with real-time traffic management and control problems.

Abstract: The paper focuses on the design of look-ahead control, in which road inclinations, speed limits and traveling time are taken into consideration. In the control system the longitudinal control incorporates the brake and traction forces to achieve the required velocity. The advantage of the method is that during the travel of the vehicle the control calculates the appropriate velocity, with which the number of unnecessary accelerations and brakings and their durations can be significantly reduced. The velocity proposed by the automatic system may interfere with the velocity selected by the driver. In the paper the system based on look-ahead control is compared to a vehicle operated by a driver using a hardware-in-the-loop simulation system.

Abstract: The maritime transportation is one of the important economic fields. It permits to exchange a huge volume of goods across the world every year. In order to ameliorate the productivity of this field, it was necessary to automate the port equipment. But this solution has some limits, particularly in optimization of handling goods operations. The ship can remain a long period of time waiting the loading or unloading operation. Several researchers had been interested in this problem; it was different modules in this field. In this paper, we are interested in assignment containers to AIV optimization problem; it includes also the AIV routing problem. We propose a resolution method; a mathematical model is made by analogy with the vehicle routing problem and the proposed approach is a genetic algorithm. An experimental calculus is made and the numerical results are acceptable.

Abstract: The paper describes the crane control application and method of designing the anti-sway crane control system based on the fuzzy logic and pole placement method. The crane control system consists of the machine vision system used to contactless measure the sway of a payload, and the untypical stereovision system based on a single camera used to capture the stereo pair of crane workspace snapshots. The method of crane workspace identification based on the stereovision system, and safe and time-optimal path planning for a payload utilizing the heuristic graph search algorithm is delivered in the paper, together with the hardware and software description of the control application.

Abstract: Automatic berthing control is one of the unresolved problems in the field of ship control. Many methods and theories were developed to achieve the goal of performing automatic berthing of ship. Among them Artificial Neural Network (ANN) has found to be the most successful one by many researchers. But still questions arise about the consistency of teaching data which are used to train ANN and also about the capability of ANN to cope with wind disturbances. To investigate such phenomena, consistent teaching data based on four virtual windows (for restricted rudder angle 10º, 15º, 20º and 25º) are created using optimal steering with the help of nonlinear programming language (NPL) method. Then trained ANN is used to validate its workability in case of no wind condition first. In case of gust wind, separate ANN is trained with reconstructed teaching data and to deal with any abrupt condition, ANN-PD controller is introduced whose effectiveness is well verified not only for teaching data but also in case of non-teaching data even in case of severe wind condition.
