Abstract ：
Previous studies mainly used statistical methods to analyze the impact of traffic composition on saturation flow rate from the mesolevel, and there is insufficient research on how traffic composition affects driving behavior. Thus, the purpose of this paper is to establish a more accurate car-following model, establish the relationship between microbehavior and mesostatistical regularity, and explain the influence of vehicle composition on saturation headway. In this paper, an improved full velocity difference (FVD) model is proposed, which abstracts the driver characteristics of a heterogeneous flow into four scenarios: car-car, car-bus, bus-car, and bus-bus. The measured data are used to calibrate and verify the basic FVD and the improved FVD models. The performance of the improved model is significantly improved. The RMSE and RMSPE are reduced by 15.29% and 22.32%, respectively. Finally, through numerical simulation experiments, the variation of saturation headway with different proportions of buses is analyzed. The saturation headway increases with the increase of the proportion of heavy vehicles. Moreover, another important finding is that the saturation headway is not significantly influenced by the position of the buses but only by the proportion of the buses. The research results could provide theoretical support for the control and management of fleets composed of different vehicles at intersections.

Abstract ：
The transit-oriented development (TOD) is an effective planning strategy for achieving the Sustainable Devel-opment Goals (SDGs) in transportation by incentivizing active transport. As an active transport with high flex-ibility and affordability, the use of dockless bike-sharing (DBS) services was affected by many identified factors. However, few studies have examined this effect from a temporally heterogeneous perspective. Here, this study aims to test if there are heterogeneous effects of station-level land-use on the use of DBS across time and to explore how and to what extent station-level land-use affects the use of DBS dynamically. Taking Beijing as a case study, this study developed the Global Linear Regression models and the Time-Varying Coefficients panel data models to estimate the heterogeneity. The results prove the existence of heterogeneity on both working days and non-working days. The daily DBS trips were significantly correlated to the density, diversity, and most types of land-use; the effect of density maintained a high level and varies with hours, and the effect of diversity showed an insignificant effect on hourly DBS trips. Besides, public management and service facilities were critical in influencing DBS usage during the daily off-peak hours, while residences always significantly and positively correlated to the use of DBS before morning peak hours and after evening peak hours. Further, the study suggests an active transfer of DBS facilities in the businesses and commercial areas to surrounding areas during non-working days. The findings guide the improvement of the service efficiency of DBS systems, and integrate DBS management strategies into TOD practice toward SDGs.

Abstract ：
Variable message signs (VMS) are widely employed to offer drivers dynamic traffic information. However, it is still lacking practical guidance about the information volume displayed on a graphical VMS. Building on the result of the subjective questionnaire survey, a static cognitive experiment was conducted to analyze the influence of volume information (i.e., elements and displaying the number of roads) of graphical VMS on drivers' visual cognition characteristics and then determine the threshold number of roads displayed on VMS. Forty-five drivers participated in the static cognitive experiment. Five indicators, including visual cognition time, cognition accuracy, comprehension accuracy, general assessment, and information acceptance, were used to estimate the influences of graphical VMS. Study results by descriptive statistics and statistical hypothesis testing indicated that drivers also preferred auxiliary elements (i.e., distance or time information) besides basic design elements (i.e., driving direction, current position, and road name) displayed on graphical VMS. With the increase in information volume, driver visual cognition time increased while other companion indexes (i.e., visual cognition accuracy and comprehension accuracy) generally worsened. Combining the data of drivers' objective behavior and subjective scoring, the Technique for Order Preference by Similarity to Ideal Solution (TOPSIS) method revealed that the number of roads shown on the graphical VMS should be no greater than five. The study results were verified by dynamic simulation experiments. This finding provides a supplement for the design standards and usage specifications for VMS.

Abstract ：
Research has revealed various relationships between regional functions, land use, and mobility features. However, how or to what extent the planned mobility features of designed regional functions differ from observed mobility features has not been sufficiently investigated. Here, the concordance between regional functions and mobility features was evaluated with datasets of dockless bike-sharing (DBS) usage and land use near metro stations. The K-means cluster method was applied to land use for capturing regional functions and to DBS features for identifying DBS usage patterns. The Kappa statistic for testing the concordance was proposed to show the differences between regional functions and mobility features. The results show poor concordance between regional functions and observed DBS features under the transit-oriented development context; the Kappa value was 0.09 on average for both DBS attraction and production. The concordance was found to be vulnerable to moderation by regional functions, on which commercial and business centers showed fair (Kappa = 0.20) and moderate (Kappa = 0.40) concordance with DBS attraction and production, respectively. The findings revalidate known relationships between land-use and mobility features based on mobility performance, and can assist in policy interventions to achieve the coordinated development of regional land-use and transportation systems.

Abstract ：
In view of the benefits and a promising prospect of the emerging connected vehicles (CV), more and more vehicles will be equipped with the in-vehicle human-machine interface (HMI). This study aims to assess the comprehensive impacts of HMIs on individual driving performance, traffic safety, and eco-driving behaviour based on a driving simulator. In order to explore how a driver responds to warnings when approaching a tunnel, this study divided the experimental road into five zones according to warning positions. A comparative analysis was conducted to examine the changes in driving comfort, speeding behaviour, the standard deviation of speed, time headway (THW), fuel consumption, and emissions. Results showed that the HMI could be beneficial to speed adjustment before entering a tunnel. Meanwhile, HMI may affect the THW of vehicles. Drivers were usually more cautious when the HMI was on. However, no significant effects of the HMI for driving comfort and eco-driving behaviour can be observed. It is expected that more efficient technology and different warning strategies can be developed to enhance eco-safe driving for different zones because they have different effects. The findings of this study are also helpful for active safety management and for evaluating the effectiveness of CV systems. © 2021 The Authors.
