This paper proposes a novel vehicle trajectory extraction method that can extract high-granularity vehicle trajectories from aerial videos. The proposed method includes video calibration, vehicle detection and tracking, lane marking identification, and vehicle motion characteristics calculation. In particular, the authors propose a Monte-Carlo-based lane marking identification approach to identify each vehicle's lane. This is a challenging problem for vehicle trajectory extraction, especially when the aerial videos are taken from a high altitude. The authors applied the proposed method to extract vehicle trajectories from several high-resolution aerial videos recorded from helicopters. The extracted dataset is named by the High-Granularity Highway Simulation (HIGH-SIM) vehicle trajectory dataset. To demonstrate the effectiveness of the proposed method and understand the quality of the HIGH-SIM dataset, we compared the HIGH-SIM dataset with a well-known dataset, the NGSIM US-101 dataset, regarding the accuracy and consistency aspects. The comparison results showed that the HIGH-SIM dataset has more reasonable speed and acceleration distributions than the NGSIM US-101 dataset. Also, the internal and platoon consistencies of the HIGH-SIM dataset give lower errors compared to the NGSIM US-101 dataset. To benefit future research, the authors have published the HIGH-SIM dataset online for public use.</p></div>","PeriodicalId":100292,"journal":{"name":"Communications in Transportation Research","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2772424721000147/pdfft?md5=9ef534362f55ca64e1d805fc202b1e16&pid=1-s2.0-S2772424721000147-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85754954","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The study found that people's initial opinions toward AV safety are significantly associated with people's age, personal income, monthly fuel cost, education experience, and previous AV experience. Further, the factors dominating people's opinion change after a successful AV ride include people's age, personal income, monthly fuel cost, daily commute time, driving alone indicator, willingness to pay for AV technology, and previous AV experience.

Different from existing studies, which focus mostly on ego vehicle objectives to control CAVs in an individualistic manner, we devise a pro-social control algorithm. The latter takes into account the objectives (i.e., driving comfort and traffic efficiency) of both the ego vehicle and surrounding HDVs to improve smoothness of the entire observable traffic. Under a model predictive control (MPC) framework that uses acceleration and lane change sequences of CAVs as optimization variables, the problem of individualistic, altruistic, and pro-social control is formulated as a non-convex mixed-integer nonlinear program (MINLP) and relaxed to a convex quadratic program through converting the piece-wise-linear constraints due to the optimal velocity with relative velocity (OVRV) car-following model into linear constraints by introducing slack variables. Low-fidelity simulations using the OVRV model and high-fidelity simulations using PTV VISSIM simulator show that pro-social and altruistic control can provide significant performance gains over individualistic driving in terms of efficiency and comfort on both single- and multi-lane roads.</p></div>","PeriodicalId":100292,"journal":{"name":"Communications in Transportation Research","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2772424721000196/pdfft?md5=acbab8cff4ba51aea10b8bbfb61c0406&pid=1-s2.0-S2772424721000196-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"137057472","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A connected environment is expected to assist during lane-changing manoeuvres, but it is not known well how driving aids in a connected environment assist lane-changing execution. As such, this study investigates the impact of a connected environment on lane-changing execution time during mandatory and discretionary lane-changing manoeuvres. To this end, this study designed an advanced driving simulator experiment where 78 drivers performed these manoeuvres on a simulated motorway in three randomised driving conditions. The conditions were baseline (without driving aids), a fully functioning connected environment with a perfect supply of driving aids, and an impaired connected environment with delayed driving aids. The lane-changing execution time has been modelled by a random parameters hazard-based duration modelling approach, which accounts for the panel nature of data and captures the unobserved heterogeneity. Results suggest that, compared to the baseline condition (i.e., a non-connected environment), most of the drivers in the connected environment take more time to complete their lane-changing manoeuvres, indicating drivers’ safer lane-changing execution behaviour in the connected environment. The communication delay driving condition has been found to have more deteriorating effects on mandatory lane-changing manoeuvres than discretionary lane-changing manoeuvres. This study concludes that (i) the connected environment increases safety margin during both lane-changing manoeuvres, and (ii) a higher magnitude of safety margin is observed during mandatory lane-changing manoeuvres whereby drivers have a higher need for assistance.</p></div>","PeriodicalId":100292,"journal":{"name":"Communications in Transportation Research","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2772424721000093/pdfft?md5=892edbfc57a2b5ac32567d999e0958e8&pid=1-s2.0-S2772424721000093-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77252343","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Increased transport and urbanization enable the many benefits of modern socieities through specialization of labour, production and lifestyles – but these trends simultaneously increase the drawbacks of transportation, such as carbon emissions, congestion, noise and air quality problems. Technical developments and improved infrastrastructure can help reduce these drawbacks, but they do not solve the fundamental problem that those reaping the benefits of transport – travellers, firms, customers – do not perceive the full social costs of transportation. To balance transport costs and benefits, efficient pricing is necessary. Despite a wealth of theoretical arguments, technical developments and substantial practical experience, efficient transport pricing is still rare. Focusing on the example of urban congestion pricing, this paper summarizes why transport pricing is needed, lessons learnt from practical experience, and what the main obstacles are. The two most important obstacles seem to be political power struggles between different levels of governments, and that even if total social gains vastly exceed total social losses, the losses tend to be more salient; losers tend to be easy to identify, while winners tend to be more dispersed and perhaps only exist in the future.</p></div>","PeriodicalId":100292,"journal":{"name":"Communications in Transportation Research","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/j.commtr.2021.100006","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86556378","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

First, we simulate errors in demand prediction through unbiased noise distributions that vary considerably in shape. Using the noisy predictions, we then simulate and optimize demand-responsive PT fleets via a linear programming formulation and measure their performance. Our results suggest that the optimized performance is mainly affected by the skew of the noise distribution and the presence of infrequently large prediction errors. In particular, the optimized performance can improve under non-Gaussian vs. Gaussian noise. We also find that dynamic routing could reduce trip time by at least 23<em>%</em> vs. static routing.
