This paper resolves the modelling problem of target vehicle’s lateral motion in real-traffic tracking applications. We incorporate CTR (Constant turn rate) model with UKF (Unscented Kalman Filter) algorithm to deal with the vehicle’s turning maneuver on curve road segment for a high accurate vehicle motion estimation. In order to test the proposed model’s accuracy and applicability under complex real road environment, we design a traffic simulation experiment and drive the test vehicle to pass a turning road. The yaw rate and position information, which could be collected by smartphone sensor (gyroscopes, GPS and orientation sensor), are considered as observed value. Then, vehicle motion trajectory can be accurately obtained after the computation of the proposed model. Comparing with other vehicle motion information fusion algorithms, the result shows the proposed model presents a better accuracy in estimating and predicting vehicle lateral motion state on curve road segment.

In this paper, a Forward Collision Warning (FCW) system based on Dedicated Shortrange Communications (DSRC) technology is built to improve vehicle driving safety and reduce traffic accidents. When the Time to Collision (TTC) and the Collision Avoidance Range (CAR) system calculated show that the vehicle is in danger of collision, the driver will be alerted via the voice and visual interface. In order to evaluate the safety and reliability of the warning system, several groups of field experiments were carried out to test the system performance, including the positioning accuracy of Differential GPS (DGPS), the communication quality of DSRC and the trigger of FCW system. We confirm the operation of the FCW system.

In order to reconstruct the panoramic model and extract plant community structure characteristics rapidly and accurately for the highway central green belt, a method for rapidly acquiring images of the targets highway central green belt using quad rotor unmanned aerial vehicle (UAV) and digital image processing techniques is explored. It has the advantages of real-time, high flexibility and low cost to obtain the plant information of the green belt in the middle of the road based on the low-altitude unmanned aerial vehicle. The results show that the images acquired with a lower flight height (30 m and 50 m) can be used to produce rather high quality Ortho-mosaic, 3D point cloud reconstruction and ideal digital surface model. The density of 3D reconstruction point cloud for the target sections is even, and the single-pixel resolution of the ortho-mosaic image can reach 0.67 cm and 1.0 cm, respectively. Thus, it can be seen that the UAV platform can obtain high-precision panoramic reconstruction of monitoring areas with different road types.

In recent years, the scale of offshore wind farms is increasing because of the high efficiency and pollution-free wind power resources. However, the introduction of many facilities in the corresponding wind farm sea area has led to the increasing difficulty of ship navigation. Therefore, it is very important to plan safe and efficient driving path according to the corresponding starting and ending points for the navigation of ships in the increasing wind farm area. In this paper, a path planning algorithm based on the hybrid method of A* algorithm and reinforcement learning is proposed, which can plan an effective collision avoidance path for the sea area of wind farm. Then the method is used to simulate the ship’s path planning in a wind farm, which proves the feasibility of the method. Finally, it shows that the method has universal reference significance for ship navigation in the wind farm waters.

Superhydrophobic surfaces (water contact angle $thetagt 150^{circ}$) with a low contact angle hysteresis have attracted much attention as a new route for antifouling and drag reduction applications. The last decade has witnessed the significant development in the design of superhydrophobic surfaces in Cassie-Baxter state inspired by the lotus leaf in nature. In this study, a simple fabrication method was developed to prepare a superhydrophobic surfaces in CassieBaxter state. The approach involved the formation of a rough structure and fluorination treatment on substrate. The asprepared surface became superhydrophobic based on the combination of rough structures and low-energy compositions. The air layer captured within the rough structures effectively prevent microorganisms’ adhesion. Meanwhile, the results indicate that the superhydrophobic surfaces show drag reduction for the air/liquid contact. The work provides a simple and highly efficient method to fabricate superhydrophobic surfaces for potential antifouling and drag reduction applications.

In order to determine the relationship between the collision speed and the crack radius of the windshield during the collision of pedestrians and vehicles, the Finite Element model of the crack propagation of the windshield, the multi-body model of the collision between pedestrians and vehicles, and the improved coupling model were constructed. On this basis, the impact of the constructed parameters on the collision response was analyzed and the reasonable parameters were determined. Furthermore, the validity of the model was verified by the actual accident cases. By the collision simulation with a speed of 10-15m/s and a deceleration of 6m/s2, the radius of the annular crack under the corresponding collision condition and an empirical formula for the collision velocity and the radius were obtained. The conclusions can provide new ideas and methods for the reconstruction of collision speed.

The establishment of a reasonable container port safety production standardization evaluation system can effectively promote the construction of port safety production standardization system, and improve the safety management level of container ports. This paper constructs a standardization evaluation system of container port safety production, which is composed of 15 first-level indexes and 46 second-level indexes. The entropy weight method is used to determine the index weight, and the fuzzy comprehensive evaluation method is used to evaluate the container production safety standardization level. This paper makes an empirical analysis on the standardization evaluation system of container port safety production by using the data of two container ports along the Yangtze River in China, puts forward some suggestions on the development of safety work, according to the evaluation results, and also provides a reference about the standardization of safety production for other container ports.

A risk assessment model based on the D-S evidence theory is proposed to solve problems concerning the security risks of tourism in inland waterways. First, we explain the risk assessment index system and describe the steps for the inland waterway cruise ship navigation safety assessment. Second, we evaluate all indicators at the bottom level and transform them into the distribution of belief items. Finally, we apply the evidential reasoning (ER) approach to merge the belief structure information with the index level, in order to obtain the evaluation indicators. Subsequently, it would be possible for us to obtain the assessment results of the goal level in a comparable way. The evaluation results are presented through a belief assignment form, but it is necessary to transform the distribution information into crisp values for comparison purposes, by using a comprehensive evaluation function. Furthermore, we also conducted a case study on the Lijiaxia reservoir, to present and validate the proposed model and the corresponding methods. The results show that the safety evaluation score of the investigated waterway is 3.06, a value that can be considered to be of an intermediate level. Thus, it can be seen that the risk grade generated from the proposed model tends to be consistent with the real safety state of the waterway.

Urban road structure is an important factor affecting the distribution of urban logistics industry. As the core carrier and organization subject of logistics space, logistics nodes and logistics enterprises have important significance for optimizing the spatial layout of urban logistics and rational allocation of logistics resources. Based on the Baidu Point of Interest (POI) platform, this paper collect massive data of logistics nodes, logistics enterprises and logistics facilities in Wuhan, study the spatial accessibility and logistics of road networks and the agglomeration characteristics of logistics industry by using spatial syntax model and GIS nuclear density method, and the relationship between them is illustrated by bivariate analysis. The results show that: 1 The overall distribution of the logistics industry is characterized by a spatial pattern of Chinese character “North”-shaped distribution along the banks of the Yangtze River, and different types of POIs are presented in different layouts and hierarchical levels. Among them, the logistics nodes are concentrated in the city center, the logistics facilities are around City ring line, and logistics enterprises match the industrial layout. 2 The roads in the central city, the urban ring road and the external traffic circle have good permeability, and can quickly realize the space connection, so it corresponds to the area where the logistics industry is highly concentrated.
