A large percentage of traffic accidents are due to human errors. Driving behavior and driving stress influence the probability of making these mistakes. Both are influenced by multiple factors, among which might be elements such as age, gender, sleeping hours, or working hours. The objective of this paper is to study, in a real scenario and without forcing the driver’s state, the relationship between driving behavior, driving stress, and these elements. Furthermore, we aim to provide guidelines to improve driving assistants. In this study, we used 1050 driving samples obtained from 35 volunteers. The driving samples correspond to regular commutes from home to the workplace. ANOVA and ANCOVA tests were carried out to check if there are significant differences in the four factors analyzed. Although the results show that driving behavior and driving stress are affected by gender, age, and sleeping hours, the most critical variable is working hours. Drivers with long working days suffer significantly more driving stress compared to other drivers, with the corresponding effect on their driving style. These drivers were the worst at maintaining the safety distance.

The transport network and mobility aspects are constantly changing, and major changes are expected in the coming years in terms of safety and sustainability purposes. In this paper, we present the main conclusions and analysis of data collected from a survey of drivers in Spain and Portugal regarding user preferences, highlighting the main functionalities and behavior that an advanced driver assistance system must have in order to grant it special importance on the road to prevent accidents and also to enable drivers to have a pleasant journey. Based on the results obtained from the survey, we developed and present a working prototype for an advanced driver assistance system (ADAS), its architecture and rules systems that allowed us to create and test some scenarios in a real environment.

Road accidents and safe driving are one of the main concerns of transportation systems and the companies that explore different solutions to reduce the accident rate. The most interesting option to achieve this goal is through an on-board training of professional drivers to apply safe driving techniques during their work activity. The purpose of this study is to analyze a monitoring system that is not limited to the real-time vehicle tracking but is also capable of monitoring and providing real-time feedback and in-vehicle training. We analyze the influence of different sociodemographic factors on driving behavior. The analyzed data correspond to an urban public transport company, obtained from a study performed on 246 drivers. The drivers received training based on a blended learning system with an on-board feedback device, accompanied by both theoretical and practical sessions. The driving behavior of each driver is obtained from the data gathered from the vehicles that allow us to characterize their driving patterns. The information related to safe driving is completed with a list of the records of road accidents. The results of the sociodemographic influence on driving behavior provide significant information, giving an elaborated classification of safety driving patterns in order to apply intelligent transportation systems.

Globalization has increased the number of road trips and vehicles. The result has been an intensification of traffic accidents, which are becoming one of the most important causes of death worldwide. Traffic accidents are often due to human error, the probability of which increases when the cognitive ability of the driver decreases. Cognitive capacity is closely related to the driver’s mental state, as well as other external factors such as the CO2 concentration inside the vehicle. The objective of this work is to analyze how these elements affect driving. We have conducted an experiment with 50 drivers who have driven for 25 min using a driving simulator. These drivers completed a survey at the start and end of the experiment to obtain information about their mental state. In addition, during the test, their stress level was monitored using biometric sensors and the state of the environment (temperature, humidity and CO2 level) was recorded. The results of the experiment show that the initial level of stress and tiredness of the driver can have a strong impact on stress, driving behavior and fatigue produced by the driving test. Other elements such as sadness and the conditions of the interior of the vehicle also cause impaired driving and affect compliance with traffic regulations.

Interest in energy cost saving and in global warming have persuaded transport companies to apply measures to reduce fuel consumption. Efficient driving is one of the most employed solutions as it allows savings in fuel consumption of around 10% with a minimal investment. The drawback is that efficient driving is a learning process, and it greatly depends on the drivers' behavior, which in turn is closely related to their motivation. If drivers are not really involved or after some time their interest decreases, efficiency improvements would disappear. Thus, an efficient driving program should make drivers' motivation one of the main targets. One option could be the implementation of reward programs. However, these should be based on a clear individual evaluation process, as an unfair system could lead to discomfort, complaints, and repudiation. In this paper, we propose an analytic system, based on the detection of efficient and inefficient behavioral patterns, to evaluate the individual driver's progression in efficient driving with the aim of being the basis of a reward program. The system receives relevant, driving related, vehicle information every 1.5 s, allowing a precise searching of patterns. It has been tested successfully in 16 bus companies, analyzing the performance of 880 professional drivers. To accurately illustrate the analytic process, three detailed driver analyses have been included as a case study. Results of this applied research on the eco-driving field show that the proposed system identifies efficient and inefficient actions that are used to fairly evaluate the drivers' performance.

Diesel engines of the vehicles in the transport sector are responsible for most of the CO2 emissions into the environment. An alternative to reduce fuel consumption is to promote efficient driving techniques. The aim of this paper is to assess the impact of efficient driving on fuel consumption in professional fleets. Data captured from the engine control unit (ECU) of the vehicles are complemented with external information from weather stations and context data from the transport companies. The paper proposes linear and quadratic models in order to quantify the impact of all the terms influencing energy consumption. The analysis was made from the traces captured from a passenger transport company in Spain with more than 50 bus routes. 20 vehicles of five different models were monitored and 58 drivers participated in the study. The results indicate that efficient driving has significant influence on fuel consumption, which confirms efficient driving as a valid and economical option for reducing consumption and therefore emissions of harmful particles into the atmosphere. According to the proposed model, in average external conditions, a driver that increases efficiency from 25% to 75% can reach savings in fuel consumption of up to 16 L/100 km in the analysed bus fleet, which is a significant improvement considering the long distances covered by professionals of the transport sector.

In recent years, the number of on-board devices that provide information about the vehicle, the driving process and the environment has increased. Nevertheless, these devices can be very distracting. Head-up display devices (HUDs) and speech recognition may be good technologies to enrich the experience of drivers while keeping safety under control. Thus, the purpose of this study is to carry out an evaluation of these technologies under real conditions. A total of 50 drivers participated in a study divided into two parts. In the first part, we performed an evaluation of the usage of driving assistants with HUD devices under real conditions. We also compared HUDs with conventional head-down display (HDD) screens. Finally, we asked users about their opinion on methods of interaction with HUDs. Considering the results, the second part of the study aimed at evaluating interaction with HUD devices using speech recognition. 65% of the drivers prefer to use HUDs instead of HDDs for safety reasons. Furthermore, the participants prefer to interact with HUDs using voice commands. 86.66% of the users stated that this method of interaction improved their feeling of safety. The main conclusion is that users agree that driving assistants combined with HUDs are useful and safe at the same time. Moreover, the interaction with HUDs through voice commands is accepted by the majority of the users; it improves their sensation of safety because they do not need to look away from the road to use driving assistants.

En el corto plazo, la industria del robot autónomo y de los drones será un factor de desarrollo importante. Tanto la fabricación de los propios dispositivos, como del desarrollo del software que los hace funcionar serán actividades empresariales de importancia en el sector TIC. No obstante, el futuro de los robots de trabajo autónomo es colaborar unos con otros y con el entorno que los rodea (adaptación al contexto). Para ello, deben de ser capaces de interactuar con otros equipos mediante protocolos de comunicación y sistemas de razonamiento. Por ello, en este trabajo se presenta una experiencia encaminada a la obtención de un sistema de trabajo colaborativo para que un grupo/enjambre de robots autónomos de limpieza puedan trabajar de forma conjunta. La experiencia se basa en un laboratorio abierto que permite a los alumnos proponer y realizar sus propios desarrollos. En el trabajo se presentan tanto los aspectos metodológicos de la experiencia, como los avances que se han conseguido realizar hasta la fecha.

El sector del transporte es uno de los principales causantes de la emisión de partículas contaminantes del medioambiente. Entre las diferentes alternativas para la reducción de consumo y de emisión de partículas nocivas la más atractiva para las empresas de transporte profesional es la utilización de técnicas de conducción eficiente ya que permite aprovechar la flota de vehículos existente sin necesidad de invertir en nuevos vehículos y tecnología. En este trabajo se ha determinado cuál sería la técnica óptima de conducción para minimizar el consumo de combustible en una ruta. Los resultados pueden aplicarse en cursos de formación en conducción eficiente. Para los cálculos se han tomado datos reales de una flota profesional de autobuses, se ha obtenido un modelo de consumo y mediante optimización de rutas se ha determinado la técnica de conducción que minimiza el consumo en la ruta analizada. Los resultados indican que la conducción eficiente tiene una influencia muy significativa en el consumo de combustible. Con una conducción óptima podrían alcanzarse reducciones en el consumo de hasta 15 litros/100km, un 28% menos, en la ruta analizada, lo cual redunda en una reducción notable de consumo en el global de la compañía, considerando las grandes distancias recorridas por los profesionales del sector del transporte.

Public transport companies face great expenses. In order to be profitable companies, they need to reduce costs in all aspects. In addition, many countries have increased taxes to force transport companies to reduce their fuel consumption and, thus, greenhouse effect emissions. Efficient driving is the cheapest way to achieve this goal. In this paper, we analyze the economic impact of one of the most influential efficient driving techniques in an urban bus company. We calculate the difference of consumption between a well-performed deceleration using the inertia of the vehicle and a loss of speed obtained by using the brakes. For this purpose, we compare a real track performed by any driver in a precise vehicle with a simulated ideal track. To obtain the deceleration of the simulation, we develop a linear regression model on over 170,000 samples captured from the same vehicle over a period of one month. The results show that the costs of the vehicle under test in one month may be reduced by more than2500€

Efficient driving has been positioned as the most popular alternative to reduce air pollution and obtain fuel savings. However, efficient driving requires a continuous learning process in order to prevent users reverting to their original habits. To facilitate the learning process, on-board tutoring systems have appeared. In this study, the authors analyse in detail the impact of two types of such eco-feedback devices on driver's behaviour. The evaluated tutoring systems include information related to the optimal engaged gear, but also related to other safety and comfort parameters. Their analysis is based on one of the largest and heterogeneous population groups of non-professional drivers who have participated in experiments with feedback devices specifically designed to achieve more efficient driving. A total number of 158 volunteers participated in the experiments covering periods of time between 3 and 11 months and using the feedback devices during their daily routine. Results show that, in general, users evolve positively following the eco-driving recommendations throughout the duration of the experiments. In addition, there are significant differences in the use of the tutoring system depending on the type of route, the time of day and other factors such as age or gender.

In the last years the number of devices that provide information about the car the driving process has increased considerably. This also implies an increased level of distraction and, thus, a decrease in safety. In this context, Head-Up Display devices (HUDs) may be considered adequate representation interfaces because they are transparent and they are located in the vision line of the driver. HUDs allow drivers to view what is behind the screen without looking away from the road. However, we must analyse the impact of these devices in order to fully consider them safe in a driving context. In this paper we present an evaluation of HUDs in a real driving context, analysing different kinds of information. Firstly, we assess the display of efficient driving data gathered from a mobile app. Next, we compare HUDs with conventional devices. Finally, we perform several tests using a GPS assistant, due to the current relevance of these services. A total of 20 non-professional drivers have participated in the experiments. They had to drive vehicles equipped with a HUD display. We evaluate the subjective opinion of the users using questionnaires in order to know whether HUDs are acceptable in a vehicle or not. Results show a positive feedback from users and a high sensation of safety.

Nowadays, access to multimedia content is one of the most demanded services on the Internet. However, the transmission of audio and video over these networks is not free of problems that negatively affect user experience. Factors such as low image quality, cuts during playback or losses of audio or video, among others, can occur and there is no clear idea about the level of distortion introduced in the perceived quality. For that reason, different impairments should be evaluated based on user opinions, with the aim of analyzing the impact in the perceived quality. In this work, we carried out a subjective evaluation of different types of impairments with different types of contents, including news, cartoons, sports and action movies. A total of 100 individuals, between the ages of 20 and 68, participated in the subjective study. Results show that short-term rebuffering events negatively affect the quality of experience and that desynchronization between audio and video is the least annoying impairment. Moreover, we found that the content type determines the subjective results according to the impairment present during the playback.

Opportunistic networking can help emergency services in both their daily operation and disaster relief. This idea has been extensively explored in previous research, but most studies are based on little knowledge of real mobility. In order to support future research, this paper analyses one year of GPS traces from a fire department. The results reveal the characteristics of hypothetic opportunistic networks formed by devices following this mobility considering different communication ranges. We found that the networks analysed are heterogeneous in many dimensions. They are also sparse and partitioned, but delay-tolerant routes connecting these partitions exist. To ease the discovery of these routes, we reveal in the connections between nodes. These findings can be applied in the design and deployment of solutions from the physical to the application layer.

Concerns about global warming and energy costs have induced transport companies to take measures to reduce fuel consumption. Among the different options available, efficient driving is widely used, allowing a reduction in fuel consumption of around 10%. However, changing the driver's behavior is not exempt of problems. The success of efficient driving techniques in the long term is related to the motivation of the driver and, for that reason, an adaptive training system according to the driver's needs can prove much more successful than giving general instructions that do not solve their inefficiencies. Therefore, a properly description of the driver's behavior and the adaptation of the evaluation analysis to the context is a key factor for the learning process in efficient driving. In this paper we propose an adaptive learning system for efficient driving, which allows the evaluation of professional drivers of urban public transport in their work environment. With the proposed system, we can identify failure points relating to the context, making a focused evaluation. The first evaluation results show that the set of patterns designed to evaluate the application of efficient driving techniques can identify the incorrect actions of the drivers. Based on the results, it is possible to make personalized recommendations to improve driver performance.

Remote controls are especially problematic for writing text, something necessary in many interactive digital TV applications (IDTV). In the context of research aimed at finding effective entry methods for IDTV applications, an empirical investigation was carried out and is presented in this article. The study analyzed the errors committed by 82 users in an experiment in which they wrote 7,395 sentences. Several typing methods suitable for IDTV contexts were used for experimentation. There were 3,562 of the sentences that registered at least one error. These errors were classified and their main causes analyzed, the particular characteristics of the users taken into account. The results show that the most frequent errors are proximity mistakes in all the evaluated methods. They appear in between 13.75% and 32.31% of the sentences, depending on the input method. Also, age and background are major aspects affecting the number and type of mistakes. The results could be the basis of changes in the design of conventional remote controls or in the design of advanced techniques for error recognition and correction.
