Personnel emergency evacuation after a ship accident is the last defense to guarantee lives and properties. To understand the influence factors of the evacuation efficiency so as to develop rational evacuation schemes for different evacuation scenes, this paper builds a simulation model of double deck by Pathfinder in which four evacuation scenarios are set referring to the IMO guidelines. From the three perspectives of evacuation time, congestion degree and exit efficiency, the author compares and analyzes the evacuation situation between choosing exits under the principle of proximity and that under the guidance of an evacuation plan. The results show that the selection of exits under the guidance of evacuation plan can promote the utilization of exits, effectively reduce the congestion degree in the evacuation process, and then shorten the evacuation time. In this paper, the study of passenger ship personnel emergency evacuation can be used to identify the congestion points of the existing passenger ship geometric arrangement, optimize the ship structure design, and improve the efficiency of passenger ship personnel evacuation.

New energy vehicles play a pivotal role in the realization of carbon peak and carbon neutrality. The prediction of the ownership of new energy vehicles is of great significance to realize the goal of environmental protection in transportation field. The fluctuations of new energy vehicle ownership data follow a long-term nonlinear trend influenced by complex impact factors where nonlinear relationships are in between. Therefore, it is important to use reasonable and accurate methods to analyze and forecast the new energy vehicle ownership to facilitate the rational formulation of policies. In order to study the change of vehicle ownership under the influence of multiple factors such as GDP, urbanization rate and highway mileage, the method of combining principal component factor analysis and logistic nonlinear model is adopted. The result shows that the nonlinear logistic regression curve obtained has a higher fitting degree with the actual data. According to the industry planning, the number of new energy vehicles in 2035 is about 156 million.

Traffic network design is one of the core contents of traffic planning. The traditional transportation planning is based on deterministic assumptions and decision-making rules, resulting in unreasonable factors in the planning scheme. This study aims to build uncertain transport network design method with uncertainty theory. This paper assumes that the traffic supply and demand are random variables. Using the expected utility theory to consider the risk attitude of users and the deviation degree to considering the risk attitude of decision maker, a bi-level programming model is established. This paper presents a method with genetic algorithm to solve the problem, and then gives an example. The results of the Nguyen Dupuis network show that the risk attitudes of decision makers and users have an important impact on the decision-making of network design. The proposed method can effectively improve the robustness of network design.

By summarizing the research on the existing expressway emergency rescue system and comprehensively considering the state of drivers and passengers after an accident on the expressway, a new expressway emergency rescue system with "1 + 1" mode is designed, and the field test has been started. The system can make full use of the waiting time for rescue, use big data and Internet of things technology to realize the early warning of upstream vehicles, provide reference for rescue deployment, and help to improve the survival rate of the wounded and reduce the occurrence of secondary accidents.

Natural disasters have a significant impact on highway traffic, and China has been slow to create special equipment for emergency response. The use of specialized equipment in the emergency disposal process is uncommon. The damage characteristics of highway traffic emergencies are described through the investigation of natural disaster situations. A framework for analysis of emergency disposal mission demands was constructed based on emergency disposal methods of typical damage characteristics and emergency disposal logic, and the emergency disposal special equipment competence demands mapping was established for the emergency disposal mission demands. For the emergency disposal mission, the dominating demand analysis technique "scenario-mission-competence" is offered. The emergency special equipment competence demand framework is built using this way by merging actual emergency requirements. The relevant specific technical indicators of equipment round important elements are proposed as an extension of the framework, which can reflect equipment need and support the modeling for equipment selection. The matching model is designed to depict the relationship between the need for special equipment and the demand for highway incident scenario disposal. The application explains how to use the method and verifies its effectiveness. The findings of this study suggest that the strategy can aid decision-making in determining equipment competency need and selecting special equipment for the disposal of highway traffic incidents.

Rail corrugation is among the most difficult problems in rail irregularity control of Chongqing subway which is special for its large longitudinal slope. In this study, the length of rail corrugation along the line was investigated and analyzed, the result shows the rail corrugation is closely related to the line slope and curve radius, it increases with the decrease of curve radius, meanwhile, when the line slope exceeds 30%, the occurrence of rail corrugation increases dramatically. The difference of rail corrugation at inner and outer rail of curve section also be tested, the result indicates that length and amplitude on the inner rail are larger than that of the outer rail at curve region. In addition, the rail corrugation at horizontal and vertical composite section is more serious, lead to higher vibration and noise to the wheel-rail system of subway.
