Considering the resource limitation, prioritisation of roads seems necessary for better allocation of resources. Since it is possible to investigate decision-making units (DMUs) where there are several inputs and outputs without considering any weight for them in data envelopment analysis, this method is very suitable for ranking. In order to analyse efficiency, BCC model with variable return to scale was used and given that a number of DMUs become efficient after solving the model, Anderson-Peterson method was employed to determine strong efficiency. Considering that one of the advantages of data envelopment analysis is the possibility of offering a progress model for inefficient DMUs, the essential changes in inputs and outputs of inefficient DMUs for being efficient have been mentioned.","PeriodicalId":35143,"journal":{"name":"International Journal of Vehicle Safety","volume":"9 1","pages":"253-261"},"PeriodicalIF":0.0,"publicationDate":"2017-07-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42938156","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}

We use the time-to-collision (TTC) as a main factor for calculating the FCPI. The index of FCPI is easy understanding for the driver even those who have no professional knowledge in vehicle technology. A self-learning algorithm for reducing the wrong warnings is presented for obtaining a suitable FCPI for the driver, which means that calculating the FCPI could meet each driver's behaviour. For the value of FCPI, value 0 is indicating the 0% probability of forward collision, and values 0.5 and 1 are indicating the 50% and 100% probabilities of forward collision, respectively. The experimental results guaranteed that the self-learning algorithm could figure out an optimal FCPI index for each driver to meet his/her driving behaviour and could reduce the wrong warnings.","PeriodicalId":35143,"journal":{"name":"International Journal of Vehicle Safety","volume":"9 1","pages":"196-208"},"PeriodicalIF":0.0,"publicationDate":"2017-07-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44344948","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}

During an emergency like accidents, traffic jams, etc., the vehicles in VANET are alerted with an Emergency Safety Message (ESM) through broadcasting. However, blind broadcasting of ESMs across VANETs leads to Broadcast Storm Problem (BSP) which would affect the QoS requirements of VANET. Hence, it is vital to suppress BSP to broadcast ESMs effectively. This paper proposes a Broadcast Storm Suppression Algorithm (BSSA) based on the concept of epidemic spreading, i.e. SEIR (Susceptible, Exposed, Infected and Removed) model. The broadcast storm is suppressed by finding the 'Farthest Infected Vehicle' (FIV) travelling in the direction of the ESM and recovering the other infected vehicles within the region to prevent from rebroadcasting the ESM. The SEIR model is simulated in NS-2.34 and found to outperform other popular broadcasting techniques.","PeriodicalId":35143,"journal":{"name":"International Journal of Vehicle Safety","volume":"9 1","pages":"228-252"},"PeriodicalIF":0.0,"publicationDate":"2017-07-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48613111","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}

Automotive makers have deployed a wide range of active safety systems (traction control, auto cruise and braking, collision avoidance, and lane switching) in recent years. However, these systems failed to significantly reduce road crash statistics. The automotive network comprises the vehicle, road and driver. Huge effort had been placed on the vehicle and road, whereas the driver remains the feeblest part. Consequently, automotive makers should focus their attention on monitoring drivers' emotion, which influences their driving behaviour. This study aims to explore available technology that monitors driver behaviour, besides proposing accident-stimulating emotion that affects driving. Furthermore, a conceptual framework for recognising anger and stress emotion, which is a cause of road crash, is proposed.","PeriodicalId":35143,"journal":{"name":"International Journal of Vehicle Safety","volume":"9 1","pages":"181-195"},"PeriodicalIF":0.0,"publicationDate":"2017-07-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44102632","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}

Based on the structural characteristics of the rail vehicle and its curved motion, we present an improved analytical quasi-static model. This model has the advantage of considering the roll motion. The improved model is validated through simulations, using the software ADAMS. The obtained model is used for the optimisation of the rail vehicle design. The safety criterion is evaluated using the derailment angle. A critical speed optimisation as a function of the radius of curvature and the rail vehicle design parameters is performed using genetic algorithm. The outcome of this work could help the designer in the choice of the adequate design parameters yielding the best compromise between the critical speed and the radius of curvature.","PeriodicalId":35143,"journal":{"name":"International Journal of Vehicle Safety","volume":"9 1","pages":"209-209"},"PeriodicalIF":0.0,"publicationDate":"2017-07-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43926630","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}

According to the World Health Organization, drowsiness has been the radical contributor of road fatalities. Electroencephalogram (EEG) is a physiological signal which relays the functioning of brain and is widely used in the diagnosis of neurological disorders. This study extrapolates the EEG signal analysis to examine several cognitive tasks. In this report, the EEG signal is processed to detect the behavioural patterns of the brain and drowsiness state of the drivers while performing monotonous driving for long distances. An eight-channel EEG data acquisition system is used to acquire the EEG data from 13 male volunteers. The EEG signal is pre-processed and decomposed into various rhythms by applying digital filter in MATLAB 2007b (Mathworks, Inc., USA). Time-frequency domain analysis has been done to extract certain features, PSG and PRMSD, which are statistically significant (ρ < 0.05) in the detection of drowsiness. The driving profile is classified into active and drowsy by a threshold, and linear regression analysis has been performed on the features extracted. A drowsiness index is proposed stating a positive correlation (0.8-0.9) between the total mean and the drowsy mean of the subject.","PeriodicalId":35143,"journal":{"name":"International Journal of Vehicle Safety","volume":"9 1","pages":"262-277"},"PeriodicalIF":0.0,"publicationDate":"2017-07-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42794780","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}

Based on this purpose, the vehicle minimum time manoeuvre for collision avoidance, which is treated as an optimal control problem, is firstly converted into a nonlinear programming problem by Gauss pseudospectral method (GPM) and is then solved with sequential quadratic programming (SQP). Finally, a real vehicle test was executed to verify the rationality of the proposed model and methodology. The results show that the simulation values are in good agreement with the real vehicle test values. The algorithm is not only precise, but can also shorten the evaluation period of vehicle handling stability and reduce the tremendous cost for real vehicle testing. The study can more truly simulate the emergency collision avoidance quality including the varying of minimum avoidable distance with different initial velocity.","PeriodicalId":35143,"journal":{"name":"International Journal of Vehicle Safety","volume":"64 1","pages":"120"},"PeriodicalIF":0.0,"publicationDate":"2016-10-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1504/IJVS.2016.079654","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"66693838","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}

This has become a major problem in traffic safety over the last two decades. The situation calls for more research in the field. The damping seat slide is one area of interest which is used for reducing neck injury. To reduce neck injury (whiplash), based upon new biomechanical research, the motion between head and torso should be reduced. In case of a rear-end impact, a new seat will slide backwards during the impact, which allows the motion to damp. Working Model software was used first to simulate and analyse the behaviour of the new system. Also, a test rig was developed for experimental purposes. The results show occupant protection increases with the new damping seat slide by reducing the neck injury criterion by 35%.","PeriodicalId":35143,"journal":{"name":"International Journal of Vehicle Safety","volume":"9 1","pages":"159-165"},"PeriodicalIF":0.0,"publicationDate":"2016-10-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1504/IJVS.2016.079656","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"66693880","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}
