The experimental results demonstrate that the proposed system achieves an average accuracy of 90% in an experiment with four drivers. In addition, we simulated real-time driver identification in an actual vehicle. In this experiment, we evaluated the time required to reach certain accuracy.

These modules often process point clouds sensed by light detection and ranging (LiDAR) sensors. Within the captured point cloud a large amount of points correspond to physical locations on the ground. These points do not hold information about road users, obstacles or road side infrastructure. Thus an important preprocessing step is identifying ground points to allow the object detection focusing on relevant measurements only. Within this paper we propose a ground point classification which relies on simple but effective geometric features. We evaluate the accuracy of the proposed algorithm on simulated data of different traffic scenarios. In addition, we evaluate the effectiveness of this preprocessing step based on the achieved speed up of an object detection algorithm on real world data.","PeriodicalId":395239,"journal":{"name":"2018 21st International Conference on Intelligent Transportation Systems (ITSC)","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124390013","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}

However, the reliable provision of a track-selective and constantly available location information is still unsolved and prevents the introduction of such systems so far. A contribution to overcome this issue is presented here. We show a recursive multistage filtering approach with an increased cross-track positioning accuracy, which is decisive to ensure track-selectivity. This is achieved by exploiting track-geometry constraints known in advance, as there are strict rules for the construction of railway tracks. Additionally, compact geometric track-maps can be extracted during the filtering process which are beneficial for existing train localization approaches. The filter was derived applying approximate Bayesian inference. The geometry constraints are directly incorporated in the filter design, utilizing an interacting multiple model (IMM) filter and extended Kalman filters (EKF). Throughout simulations the performance of the filter is analyzed and discussed thereafter.","PeriodicalId":395239,"journal":{"name":"2018 21st International Conference on Intelligent Transportation Systems (ITSC)","volume":"186 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117161704","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}

Adding further complexity is the increasingly important role of artificial intelligence and rapidly changing technologies and business models. We propose a modeling framework, CognAgent, which unifies the modeling approach of different types of autonomous entities from the perspective of cognition rather than revealed behaviors. This approach improves model flexibility, interpretability, and computational efficiency. Heterogeneous agents inherit from a single blueprint agent and interact with one another within the Physical Interaction module, the output of which is fed into the module of Space of Observables for agents to sense and perceive through noisy media of information transmission. Combining with prior knowledge, preprogrammed routines, emotions, and habits, agents make decisions on how to act in the Physical Interaction module. In CognAgent, information is a result of the change of perceived uncertainty, and therefore, consistent with the Information Theory. Owing to this explicitness of agents' cognition, the derived models become extendable to new technology and business models. Equity analysis related to cognitive limitations such as vision and hearing loss becomes also natural. The numerical example models explicitly humans and autonomous vehicles with heterogeneous information transmission, perception, and risk preference.","PeriodicalId":395239,"journal":{"name":"2018 21st International Conference on Intelligent Transportation Systems (ITSC)","volume":"43 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117173492","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}

Evaluation tests in a Japanese urban area showed that our proposed scheme can realize robust lane-level absolute positioning results (2DRMS, 0.9 m). In addition, the standard deviation of the heading is 0.4°, and that of the pitch angle is 0.6°. Evaluation tests showed that the accuracy of our proposed scheme almost reached levels of the survey level mapping system, which is equipped with high-cost sensors. On the other hands, the total sensor cost for our prototype was only several hundreds of dollars.

Predicting bike counts would help mitigate imbalances in the system. Research has focused on global prediction techniques but has neglected the role of user incentives. We adopted two computational techniques to capture BSS dynamics: mini-batch gradient descent for the linear regression (MBGDLR) and locally weighted regression (LWR). The two approaches used incremental learning based only on the previous status of the station with neither weather nor time information. The models were applied to a BSS data set for one year (2014–2015) in the San Francisco Bay Area for different prediction windows. Both models gave comparable results. LWR performed slightly better than MBGDLR for all prediction windows. The smallest prediction error for LWR was 0.31 bikes/station (4% prediction error) for a 15-minute prediction window and 0.32 bikes/station for MBGDLR. The 120-minute prediction window had the largest prediction error of 1.1 bikes/station and 1.2 bikes/station for LWR and MBGDLR, respectively. Computationally, MBGDLR was 55 times faster than LWR and proved to be faster than other machine learning and time series algorithms.","PeriodicalId":395239,"journal":{"name":"2018 21st International Conference on Intelligent Transportation Systems (ITSC)","volume":"42 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127532915","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, we suppose to build a vehicular edge cloud computing (VECC) framework to resolve such a vehicular computing dilemma. In this framework, potential vehicular computing tasks can be executed remotely in an edge cloud within their time latency constraints. Simultaneously, an effective wireless network resources allocation scheme is one of the essential and fundamental factors for the QoS (quality of Service) on the VECC.

One solution is to ensure that the vehicle is able to execute a collision-free evasive trajectory at any time. However, a fast method to plan these socalled fail-safe trajectories does not yet exist. Our new approach plans fail-safe trajectories in arbitrary traffic scenarios by incorporating convex optimization techniques. By integrating safety verification in the planner, we are able to generate fail-safe trajectories in real-time, which are guaranteed to be safe. At the same time, we minimize jerk to provide enhanced comfort for passengers.
