It can also be a factor for calculating other traffic information. The congestion degree can be usually calculated on the basis of sensors installed along roads. It is possible that the sensory data can be lost due to potentially unreliable communication or faulty sensors, leading to lost of important traffic data. In this paper, we propose both adaptive traffic congestion analysis system architecture as well as a novel traffic congestion estimation algorithm that can compensate missing sensory data. An ability to provide traffic condition of road segments at all time is feasible. Unlike other existing methods, our approach aims not to rely on only traffic data from sensors, but utilize discoverable external context instead. The promising experiment result and analysis are reported in this paper. In addition, the context attribute correlation analysis is also discussed.","PeriodicalId":396749,"journal":{"name":"2009 IEEE Intelligent Vehicles Symposium","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-06-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115296364","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}

Although most of these visual feature-based approaches show sound results in scenarios of limited complexity, they seem to lack the necessary system-inherent flexibility to run in complex cluttered environments under changing lighting conditions. Our proposed architecture relies on four novel approaches that make such systems more generic by autonomously adapting important system parameters to the environment. As the presented results show, the approach allows for robust road detection on unmarked inner-city streets without manual tuning of internal parameters. The described system was implemented in C relying on the Intel Performance Primitives library and proved its real-time capability. It will be a sub-module of an advanced driver assistance architecture, which runs in real-time on a test vehicle.","PeriodicalId":396749,"journal":{"name":"2009 IEEE Intelligent Vehicles Symposium","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-06-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124282412","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}

Therefore, the transformation between the image and the ground plane has to be determined with a very high accuracy. Conventional calibration methods are usually a compromise between the accuracy and a preferably small effort for the calibration set-up. In this paper, we present an efficient and robust method for an accurate estimation of the extrinsic parameters based on minimizing an error function. The idea is to avoid the difficult and time-consuming measurement of marker positions in the 3D world coordinate system which is fixed with respect to the vehicle. A pattern of circles is placed on the ground plane in front of the car. For our approach, it is only necessary to measure the relative distances between the centers of the circles to each other. A nonlinear-optimization algorithm minimizes the squared difference between the distances of the backprojected circles segmented in the images on the ground plane and of the measurement in the real world.","PeriodicalId":396749,"journal":{"name":"2009 IEEE Intelligent Vehicles Symposium","volume":"52 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-06-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127101949","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, a multi-source information fusion model to improve the driving safety for older drivers is proposed. First, the influences of surrounding features, such as traffic and weather, on the driving safety are analyzed and the surrounding driving safety degree (SDSD) is proposed to represent it. Second, we analyze the effect of driving behavior characters on the driving safety and name it as the driving behavior safety degree (DBSD). Then we propose a fuzzy information fusion method to evaluate the driver safety degree (DSD) based on the evaluation results of SDSD and DBSD. The fuzzy reasoning rules can be adjusted to satisfy different drivers through analyzing the driving behavior and history traffic accident logs collected. We test our methods based on the data sets collected from the American National Highway Traffic Safety Administration (NHTSA) and the experimental results show that the proposed method is more efficient in improving the older driver's safety.","PeriodicalId":396749,"journal":{"name":"2009 IEEE Intelligent Vehicles Symposium","volume":"232 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-06-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126042569","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}

A fuzzy controller is developed for vision based autonomous road following. The analysis and design of fuzzy control laws for steering control of the autonomous nonholonomic robotic vehicle are described. This approach utilizes Lyapunov's direct method to formulate a class of control laws that guarantee the convergence of the steering error. Certain requirements for the control laws are presented for designers to choose a suitable rule base for the fuzzy controller in order to make the system asymptotically stable. Stability of the proposed fuzzy controller is guaranteed theoretically and also demonstrated by simulation studies and experiments. Simulations using the model of the four degree of freedom nonholonomic robotic vehicle are conducted to investigate the performance of the fuzzy controller. The proposed fuzzy controller can achieve the desired steering angle and make the robotic vehicle follow the road successfully. Experiments show that the developed intelligent vehicle is able to follow a mocked road autonomously.","PeriodicalId":396749,"journal":{"name":"2009 IEEE Intelligent Vehicles Symposium","volume":"51 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-06-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126941273","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}

Moreover, obstacle extraction system is one of most important system. Here, baseline length of our stereovision system is shorter than general one so that the room mirror can cover it. Accordingly, it can be placed unobtrusively and never be unsighted for the driver. Therefore, our stereovision system is suite for interior sensor. In our previous report, we proposed an obstacle extraction method using such stereovision system, and traditional “V-Disparity” approach was extended to more flexible system by using Virtual Disparity Image. Hereby obstacles can be extracted even if the vehicle has large roll movement.

Two parameters related to U-turns were calibrated based on field data. They are (1) the saturation flow rate for U-turn and left-turn mixed traffic stream; and (2) the turning speeds for U-turning vehicles in the left-turn lane. The saturation flow rate was calculated based on the U-turn adjustment factors developed in a previous study. A linear regression model was developed for predicting the average turning speeds of U-turning vehicles at a signalized intersection given the turning radius provided at the left-turn bay. Delay reported by the calibrated Synchro and SimTraffic models was compared to the average control delay measured in the field. The effectiveness of parameter calibration differs for different signalized intersections. It was generally found that the calibrated Synchro and SimTraffic models provided reasonable delay estimates for U-turns at signalized intersections. With the calibrated and validated Synchro and SimTraffic models, sensitivity analysis was conducted to evaluate how the increased number of U-turning vehicles affects the level of service of signalized intersections. It was found that the sensitivity of the average control delay to changing U-turn volumes differs for different signalized intersections. The sensitivity analysis results suggest that the impacts of U-turns on the level of service of signalized intersections shall be evaluated on a case-by-case basis.","PeriodicalId":396749,"journal":{"name":"2009 IEEE Intelligent Vehicles Symposium","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-06-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129566157","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}
