Hence how to reduce the waiting time becomes critical. In this paper, we propose a Markov chain based traffic flow evacuation model that aims at minimizing vehicles' CO2 emissions. Here suppose we are able to obtain the steady state probability p1 of vehicles arriving at the signalized intersection and the probability pcross that vehicles can drive through the signalized intersection. Then we propose a vehicles' speed control model, it's obtained with favourable performance about vehicles' CO2 emissions through these. Simulations are conducted to verify the performances of the proposed scheme and superior performance could be observed comparing with the competing scheme in typical network scenarios.","PeriodicalId":325462,"journal":{"name":"2015 IEEE International Conference on Vehicular Electronics and Safety (ICVES)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2015-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122227576","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}

Landry","doi":"10.1109/ICVES.2015.7396885","DOIUrl":"https://doi.org/10.1109/ICVES.2015.7396885","url":null,"abstract":"This paper proposes to evaluate the driver safety by integrating the information of the Driver, the Vehicle and the Environment (DVE). The adopted strategy is composed of two fusion levels (local and global fusion levels) and use the Demptster-Shafer Theory (DST). The development of the Basic Probability Assignment (BPA) is based on the developed Fuzzy Inference System (FIS) (in the vehicle entity) and models. To reduce the complexity of the fusion problem in the Vehicle entity, the output membership function is fixed to the two developed FISs and the rule table is tuned relatively to this assumption. Application to the Canadian drivers in the city of Montreal shows the validity of the developed risk modes in case of one sample data and a driving mission. Comparison results between the Dempster-Shafer (DS) and the sixth version of the Proportional Conflict Redistribution (PCR6) combination rules show that the relevance of the PCR6 in case of high conflict between sources. Data related to the experimental test is recorded using the developed on-board data collector device that integrates an Inertial Navigation System (INS) and a Global Positioning System (GPS). Our approach assumes that the driving behavior is evaluated over the defined referential subsets which are the Low Risk (LR), Medium Risk (MR) and High Risk (HR), LE u MR and HR and the driving scores are the masses over these subsets.","PeriodicalId":325462,"journal":{"name":"2015 IEEE International Conference on Vehicular Electronics and Safety (ICVES)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2015-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130187876","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 this paper, we propose a driver intent prediction approach base on Hidden Conditional Random Fields model. The work can substantially utilize multiple dynamic characteristics of the driving signals, such as the steering wheel angle, lateral position, and drivers gaze compared with other batch process algorithm like Support Vector Machine (SVM). Moreover, it is more discriminative than traditional methods based on Hidden Markov Model (HMM). The experiments were carried out in a driving simulator, and we designed a more complex driving environment compared with previous works. In our experiment, the curvature of the road was not constant and the subjects could make lane change decision on their own. The results show that the proposed method outperforms over SVM and HMM. The prediction accuracy is 99% in 0.5s before the lane change, and 85% in 2s before the maneuver.","PeriodicalId":325462,"journal":{"name":"2015 IEEE International Conference on Vehicular Electronics and Safety (ICVES)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2015-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132519412","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}

Driving simulator experiments showed that drivers' reaction time were shortened while using the haptic DAS. However, there existed concerns regarding drivers' risk compensation behavior while using the system. Therefore, the present paper proposes an improved version of the aforementioned system. Experiments were performed to better understand the perception characteristics of seat protrusion haptic stimulus, and furthermore, new features such as a safe driving evaluation feedback were added in order to prevent drivers' risk compensation behavior. Results of driving simulator experiments indicated promising effects of the improved system in comparison to the previous system.","PeriodicalId":325462,"journal":{"name":"2015 IEEE International Conference on Vehicular Electronics and Safety (ICVES)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2015-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134579896","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}
