To this end, we propose an auction-based parking lot assignment that optimizes the parking costs and penalizes the empty cruising.To grasp a hypothetical situation, we assess the properties of the proposed mechanism by simulations. A highly abstracted circular city model is presented as a simulation environment to the parking problem, which also considers the regulations limiting the extent of empty cruising. This hypothetical model includes two kinds of parking facilities (curb-sided parking lots and parking houses), various human activity models, pricing, and distance calculations calibrated by values measured in contemporary Budapest.Simulations indicate that using an auction mechanism does not necessarily increase parking charges significantly. The results also call attention to proper empty cruising regulations as parking lot occupancy and vehicle kilometer traveled strongly depend on them.","PeriodicalId":256905,"journal":{"name":"2021 IEEE Intelligent Vehicles Symposium Workshops (IV Workshops)","volume":"45 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-07-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129992889","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 scenario-based assessment approach is accepted by many players in the field as part of the complete safety assessment. A scenario is a representation of a situation on the road to which the AV needs to respond appropriately. One way to generate the required scenario-based test descriptions is to parameterize the scenarios and to draw these parameters from a probability density function (pdf). Because the shape of the pdf is unknown beforehand, assuming a functional form of the pdf and fitting the parameters to the data may lead to inaccurate fits. As an alternative, Kernel Density Estimation (KDE) is a promising candidate for estimating the underlying pdf, because it is flexible with the underlying distribution of the parameters. Drawing random samples from a pdf estimated with KDE is possible without the need of evaluating the actual pdf, which makes it suitable for drawing random samples for, e.g., Monte Carlo methods. Sampling from a KDE while the samples satisfy a linear equality constraint, however, has not been described in the literature, as far as the authors know.In this paper, we propose a method to sample from a pdf estimated using KDE, such that the samples satisfy a linear equality constraint. We also present an algorithm of our method in pseudo-code. The method can be used to generating scenarios that have, e.g., a predetermined starting speed or to generate different types of scenarios. This paper also shows that the method for sampling scenarios can be used in case a Singular Value Decomposition (SVD) is used to reduce the dimension of the parameter vectors.","PeriodicalId":256905,"journal":{"name":"2021 IEEE Intelligent Vehicles Symposium Workshops (IV Workshops)","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-07-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133992525","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}

DRL approaches have achieved notable results, its dependability on reward functions and defining the type of control actions are dominating factors of the objective, that controls its success. Several DRL approaches applied in the past consider a finite set of available actions to be controlled by the agent hence, it performs sharp actions. While real driving requires precision control capabilities that tend to apply safer and smoother actions. For incorporating such precision control capabilities, this paper considers the driving problem as a continuous control problem. For this, the gym-highway environments are used as these environments are controllable and customizable to simulate diverse driving scenarios. The simulation setup for parking is updated to resemble the complex scenario and for highway driving a novel reward function is designed to handle continuous actions. Dual critic based DRL approaches are applied as these approaches have shown remarkable performance in robotic locomotion control problems. The video results demonstrate the way different policies fulfil the objective.","PeriodicalId":256905,"journal":{"name":"2021 IEEE Intelligent Vehicles Symposium Workshops (IV Workshops)","volume":"65 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-07-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134473225","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}

An AV must be safely guided towards its destination under different illumination conditions and avoid obstacles. Thermal infrared (TIR) camera sensors can provide robust image quality under any illumination. Past object detection work using TIR sensors focused on detecting only pedestrians by filtering thermal values. Other approaches leveraged the advantages of a pre-trained RGB-based model. However, the thermal threshold-based filtering can increase false positives depending on the TIR camera capability. Moreover, a large and new TIR training dataset is needed to improve the accuracy of the RGB-based object detection networks. The time and effort to annotate new data are significantly high. In this paper, we propose efficient and practical approaches to provide robust object detection from TIR images. We first reduce the cost of training with new data by using an automated process. To increase the final object detection accuracy, we next propose fusion methods that combine results from dual TIR camera sensors. Finally, we substantiate the practical feasibility of our approach and evaluate the substantial improvement in object detection accuracy. We use various detection networks and datasets on discrete Nvidia GPUs and an Nvidia Xavier embedded platform, commonly used by automotive OEMs.","PeriodicalId":256905,"journal":{"name":"2021 IEEE Intelligent Vehicles Symposium Workshops (IV Workshops)","volume":"118 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-07-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126055473","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 common solution is the use of virtual validation via environment simulation tools, but their reliability must first be confirmed. For this purpose, a comparison of a real and a simulated radar sensor under adverse weather conditions is performed in this work.To quantify the deviation between reality and the virtual test environment, a complex scenario with multiple traffic objects is set up on the proving ground and in the simulation. The data is measured for clear weather, rain and fog and afterwards compared to validate the performance of the sensor model under those non-ideal conditions.The implemented method shows that both sensors neglect the same traffic objects. Compared to the real radar, the variation of the measured parameters according to changing weather conditions in the simulation tends to be correct, but the values are not completely realistic.Though, the validation method is implemented successfully, in further work the comparison of different sensors is recommended. Furthermore, an in-depth examination of the impact due to varying intensity of rain and fog has to be undertaken.","PeriodicalId":256905,"journal":{"name":"2021 IEEE Intelligent Vehicles Symposium Workshops (IV Workshops)","volume":"51 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-07-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133377901","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 compare scores generated by QED against scores assigned by human evaluators on 30 different drivers and 6 different towns in the CARLA driving simulator. In \"easy\" evaluation scenarios where better drivers are easily distinguished from worse drivers, QED attains 0.96 Pearson correlation and 0.97 Spearman correlation with human evaluators, similar to the baseline inter-human-evaluator 0.96 Pearson correlation and 0.95 Spearman correlation.

One of the main reasons for this is the increase in traffic volume due to an increased number of four-wheeled vehicles. This brings about a heterogeneous (mixed) traffic flow consisting of two-wheeled vehicles and four-wheeled vehicles, which can result in the occurrence of sideswipe collisions. We carried out a survey of two-wheeled vehicle driving in heterogeneous traffic flow by considering vehicle density, acceleration, and pore (lateral gap), among other factors. Based on the results of this survey, we aim to predict motorcycle riding that carries high risk of collision, and to prevent such accidents from occurring. In this paper, we describe a novel algorithm which is capable of predicting two-wheel driving using vehicle detection and pore consideration. The performance of the proposed algorithm is verified and its associated issues are described.
