Adaptive Cruise Control (ACC) is one of the first automated functionalities available for privately owned vehicles and the deployment of such systems in public transport networks is constantly increasing. The impact of such controllers is still under investigation and there is a lot of discussion regarding their ability to positively affect congestion and pollution. In simulation studies regarding the impact of ACC on traffic flow, one key parameter is their response time. This parameter, usually takes low values, based on the controller’s theoretical ability to respond instantaneously. In the preliminary results presented by the authors in [1] based on an empirical approach, it seems that this hypothesis is not valid. The present work builds on this conclusion presenting further results on two more commercially available controllers and testing their response in both urban and highway driving conditions under normal driving behavior without critical situations regarding the safety of the vehicle’s passengers. The deployed ACC systems are primarily designed for safety and comfort. Adding on top of that the delays due to the interoperability of various vehicle systems, the final response time, that an observer would see, is very close to the human reaction time and this work shows that in some cases is even higher and by no means instantaneous. The findings here refer to normal driving conditions.","PeriodicalId":285883,"journal":{"name":"2019 6th International Conference on Models and Technologies for Intelligent Transportation Systems (MT-ITS)","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-06-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132191611","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In the application of Evolutionary Algorithms (EA) such as Genetic Algorithms (GA) and Particle Swarm Optimization (PSO) for calibration of traffic simulation models, objective function evaluation is the most time-consuming step in such calibration problems, because EA has to run a traffic simulation and calculate its corresponding objective function value once for each set of parameters. The main contribution of this study has been to develop a quick calibration procedure for the parameters of driving behavior models using EA and parallel computing techniques (PCTs). The proposed method was coded and implemented in a microscopic traffic simulation software. Two scenarios with/without PCT were analyzed using the developed methodology. The results of scenario analysis show that using an integrated calibration and PCT can reduce the total computational time of the optimization process significantly - in our experiments by 50% - and improve the optimization algorithm’s performance in a complex optimization problem. The proposed method is useful for overcoming the limitation of computational time of the existing calibration methods and can be applied to various EAs and traffic simulation software.","PeriodicalId":285883,"journal":{"name":"2019 6th International Conference on Models and Technologies for Intelligent Transportation Systems (MT-ITS)","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-06-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122167891","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Many entities are interested in accident data in order to identify current problems. The accurate recording and analysis of accident data, though, is a time-consuming task. New data mining methods allow for a more efficient analysis of large amounts of (unstructured) data. In this paper, accident data provided by the police department of the city of Munich is analyzed both by classical methods considering only classified accidents, as well as with the help of text mining methods, taking into account all descriptions of the accidents. The results indicate that text mining methods can give quick results identifying main problems at the given locations. Using statistical and machine learning methods for the analysis shows promising results. The results of the automatic classification of accidents into accident types based on a learned classification model using the textual descriptions is highly accurate. Retrieving structured information from the descriptions, though, requires a more concise writing of the accidents reports. We conclude that in future, data mining methods could be used to reduce the workload for police officers for both the reporting work as well as the analysis of road accidents.","PeriodicalId":285883,"journal":{"name":"2019 6th International Conference on Models and Technologies for Intelligent Transportation Systems (MT-ITS)","volume":"260 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117348463","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The last decade, the European Union has funded more than 140 million euros for research in innovative ITS and C-ITS technologies through the HORIZON 2020 funding mechanism.Taking into account the significance of ITS and C-ITS technologies, in the frameworks of the CAPITAL project, an ITS knowledge database has been introduced in order for a common framework to be provided for the deployment of ITS and C-ITS. The ITS knowledge database is presented in the form of Massive Open Online Courses (MOOCs) through the CAPITAL Online Training Platform, developed in the standards of other online training platforms. The solution of MOOCs has been chosen due to the fact that more and more platforms, either university platforms or not, are already introduced for providing educational programs.The ITS knowledge database consists of nine independent topic studies, with each one aiming to describe the current state of the art of ITS and C-ITS. The aforementioned topic studies are the following:•Introduction to ITS and C-ITS.•ITS and C-ITS user services.•TMC and roadside technologies for ITS.•Communication technologies for ITS and C-ITS including relevant standards.•Impact assessment of ITS and impacts of selected ITS and C-ITS systems•Financial incentives, business models and procurement models for C-ITS deployment.•Cost-benefit analyses of ITS services.•Guidance in deploying ITS and C-ITS.•Data protection and privacy.The topic studies mainly take the form of literature reviews and they are presented as video lectures. They address all ITS stakeholders, divided by their know-how level into three categories: 1st level ITS start-up communities, 2nd level intermediary communities and 3rd level professional users. The educational and informational material is customized for each individual know-how level. Every trainee has the possibility to evaluate the concept of online training tools as well as the effectiveness of this specific tool both before and after the attendance to each course. Moreover, various quizzes have been developed based on the material of each lecture separately in order to measure the level of knowledge and the information that the trainees gain after each lecture.Within this paper, a first thorough analysis of the feedback of the participants – trainees is being presented and a consequent evaluation of the effectiveness of the platform is being executed in order to identify the efficiency and the success of such an online tool. The level of awareness and demand for ITS technologies is being measured through descriptive statistics that conclude to useful results for both the material of the courses as well as the usefulness of an online training tool for ITS.","PeriodicalId":285883,"journal":{"name":"2019 6th International Conference on Models and Technologies for Intelligent Transportation Systems (MT-ITS)","volume":"2014 28","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"113966321","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The paper provides a double contribution to the research activity on sharing mobility: i) the exploration of the electric car sharing potential demand among students; ii) the implementation of an Hybrid Choice Model to analyze the role of the pro-environmental attitude on the users’ willingness to use car sharing. The analysis has been based on the data collected in a survey among the potential users of the e-go car sharing service. One of the first findings of the study is that the pro-environmental attitude doesn’t significantly influence the choice of the users. The authors suggest to the car sharing operators and to the policy makers to take in consideration the results of the study in order to plan promotional strategies and to develop policies aiming at supporting the spread of this service.","PeriodicalId":285883,"journal":{"name":"2019 6th International Conference on Models and Technologies for Intelligent Transportation Systems (MT-ITS)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130102695","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Considering the future prospect of this mode of transportation and the great advantages that it offers in terms of space consumption, health and environmental sustainability, several city authorities worldwide are presently undertaking schemes aiming at improving cycling infrastructure. The aim of the present study is to monitor the impact of such schemes on the riding comfort of cyclists, as expressed by the, usually lower, quantity and magnitude of vibrations occurring as a result of cycling over pavement defects. Millbrook Road East in the western edge of the city center of Southampton is used as a case study, where vibration measurements are taken by means of an instrumented bicycle during periods before and after a redevelopment scheme involving the resurfacing of the road pavement. The results show a clear overall improvement in cycling comfort post-redevelopment, with statistically significant reductions in both the number of high severity vibrations and of their magnitude in \"typical\" cycling trips taken on the road. However, instances of finishing \"snags\" in some parts of the surface appear to introduce new minor defects (e.g. around manholes) that are not visible to the naked eye, and these still have some negative effect on the riding experience. Moreover, the study highlights the detrimental impact that widespread pavement defects can have on riding comfort, which affect cyclists of all ages, abilities and styles.","PeriodicalId":285883,"journal":{"name":"2019 6th International Conference on Models and Technologies for Intelligent Transportation Systems (MT-ITS)","volume":"67 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127030047","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Mahmassani","doi":"10.1109/MTITS.2019.8883286","DOIUrl":"https://doi.org/10.1109/MTITS.2019.8883286","url":null,"abstract":"Simulation frameworks for autonomous mobility-on-demand (AMoD) systems are currently implemented as round-based games, where the real-world simulation time effectively stops until the fleet operator and users finish their decision-making processes. As such, these decisions, which take time to complete in the real-world, are unrealistically treated as instantaneous in the simulation.This work presents a real-time gaming framework for AMoD simulations that creates asynchronous processes to compute fleet operator decisions and delayed mode choice decisions of users (after they receive real-time information), while continuously updating the system state, i.e. moving vehicles and performing boarding processes. The framework enables a multiplayer game with multiple AMoD operators using different policies and pricing strategies to compete against each other and public transportation for on-demand travelers.Two operator strategies only available in a framework with non-instantaneous decision-making processes are introduced. The first strategy involves forecasting the future system state when the operator decision will probably be applied. The second policy sends a vehicle to the assigned request even if the corresponding user has not confirmed service with this operator yet.The framework is applied to numerical experiments in order to simulate effects of non-instantaneous operator and user decision-making. As expected, results show that operator computation time becomes relevant for the number of served requests in case of impatient users who want to make their mode choice decision shortly after their request. The new operator strategies also show beneficial behavior in the tested scenarios.","PeriodicalId":285883,"journal":{"name":"2019 6th International Conference on Models and Technologies for Intelligent Transportation Systems (MT-ITS)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125557383","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
