In order to improve the practicability and control accuracy of the trajectory tracking control algorithm and solve the problem of insufficient tracking accuracy of the target path during vehicle driving, a trajectory tracking controller based on sliding film predictive control is designed. Firstly, a two-degree-of-freedom vehicle model was established, taking into account the vehicle’s steering characteristics; Then, a sliding mode controller was designed. By choosing the appropriate sliding mod...

With the formulation of the “double carbon” target, the transportation industry has become an important part of the low carbon field, and the “decarbonization” target of the automobile industry has become imperative. This paper focuses on the automobile carbon neutrality, discusses the areas of automobile carbon footprint, and analyzes the path of automobile carbon neutrality. With the technical support and policy encouragement of the government, automobile enterprises in various countries promo...

The research on land transport contributes to the efforts made by nations to promote road safety. This paper investigates tendencies that contribute to the emergence of accidents involving commercial motorcycles due to human errors in urban. Specifically, it analyses the riding tendencies leading to accidents and their associated factors. The data were collected through observation, documentary review and focus group discussion along Morogoro road, specifically at Ubungo and Fire junctions.

Autonomous robotics is one of the key subjects of this generation of research and has grown to be more and more popular in recent years, especially in such industries, hospitals, hotels, and plenty more. Path planning is a critical issue in the applications of these autonomous mobile robots. This means the path planning task is to find a collision-free path for the robot, in an indoor environment that has cluttered obstacles, from the specified beginning or start point to the end or desired goal...

It is of practical value and significance to study the influencing factors of the headway capability of moving block system. This paper mainly analyzes the factors affecting the train headway capability in urban rail transit from two aspects: safety braking model and dwell time. The balanced transport capacity of the whole line is realized with reasonable optimization of train speed limit, GEBR value and dwell time value. At the same time, it also puts forward the optimization of the above influ...

In the current research work, attempt was made to evaluate the tail pipe exhaust CO emission deviations through cerium oxide (CeO₂) nano particle involvement in Madhuca indica biodiesel (MIB). The Madhuca indica biodiesel is extracted from the seeds of the corresponding plant, and then it is processed to derive the biodiesel. The derived biodiesel is then blended with the normal diesel fuel with different propositions. The amount of CO emission percentage variation of the biodiesel bl...

The rise of online food ordering has led to a proliferation of delivery riders, serving as the final link in the online-to-offline transport chain. Delivery riders are crucial in ensuring customer satisfaction and food integrity, akin to traditional restaurant waiters. However, they face challenges in maintaining food safety standards during transportation and adhering to road safety regulations. The study investigates the food and road safety practices of delivery riders in Accra, Ghana, amid t...

On two-lane, two-way highways faster vehicles frequently overtake slower moving vehicles. In order to secure a safe passing maneuver, the passing driver should be able to see a sufficient distance ahead, clear of traffic, to complete the passing maneuver without cutting off the passed vehicle before meeting an opposing vehicle. This is called the minimum recommended passing sight distance ahead, which is considered as an important factor in the marking of passing zones and no-passing zones along...
