“…CO and CO 2 in transport environments have also been subjects of frequent investigation, with approximately 40 studies conducted for each pollutant. Examples of such studies include those by [172][173][174][175][176]. Other pollutants, such as NO 2 , O 3 , SO 2 , and metals, have received less attention in the literature, with fewer studies conducted on these substances.…”

People spend approximately 90% of their day in confined spaces (at home, work, school or in transit). During these periods, exposure to high concentrations of atmospheric pollutants can pose serious health risks, particularly to the respiratory system. The objective of this paper is to define a framework of the existing literature on the assessment of air quality in various transport microenvironments. A total of 297 papers, published from 2002 to 2021, were analyzed with respect to the type of transport microenvironments, the pollutants monitored, the concentrations measured and the sampling methods adopted. The analysis emphasizes the increasing interest in this topic, particularly regarding the evaluation of exposure in moving cars and buses. It specifically focuses on the exposure of occupants to atmospheric particulate matter (PM) and total volatile organic compounds (TVOCs). Concentrations of these pollutants can reach several hundreds of µg/m3 in some cases, significantly exceeding the recommended levels. The findings presented in this paper serve as a valuable resource for urban planners and decision-makers in formulating effective urban policies.

“…By using the method of feature alignment, combined with the sampling time delay, the global effective quantitative feature distribution set of automatic monitoring data of motor vehicle pollutant emissions is extracted [ 10 – 12 ], and the limited data set of automatic monitoring data of motor vehicle pollutant emissions is obtained as: Wherein, the automatic monitoring data set of motor vehicle pollutant emissions contains n samples, for sample , . The quantitative relationship between the process of automatic monitoring of motor vehicle pollutant emissions is obtained by using the method of identifying related parameters.…”

To improve that automatic monitoring capability of the vehicle’s pollutant discharge, a design method of the auto-monitor system for the emission of vehicle pollutant is proposed based on the fusion algorithm. The system design includes a large data analysis model design and system software for automatic monitoring of vehicle pollutant discharge. In that method, a quantitative statistical analysis method is adopt to carry out cloud computing fusion processing of automatic monitoring of pollutant discharge of a motor vehicle, and the invention relates to an information fusion and recombination model for automatically monitoring large data of pollutant discharge of a motor vehicle, the method of automatic monitoring of vehicle pollutant discharge based on the fusion algorithm is improved by the effective feature of the automatic monitoring of the pollutant discharge of the motor vehicle. In the development of B/S and embedded PCI bus, the software development and design of the automatic monitoring system for pollutant discharge of motor vehicle are carried out, and the hardware structure and software development of the automatic monitoring system for pollutant discharge of motor vehicle are carried out. The results of the test show that the automatic monitoring system for motor vehicle pollutant discharge is good in stability and strong in the sampling and statistical analysis of the physical information.

“…Since tunnels are partially enclosed, maintaining an efficient ventilation system within them is vital. In the survey of motorway tunnels, Mohammad et al discovered a significant increase in the concentration of CO and particulate matter in the compartment once cars entered tunnels that possessed poor ventilation systems 2 . Effective exhausting of the exhaust air in a semienclosed tunnel space is necessary to maintain a good tunnel environment.…”

In recent years, research on ventilating tunnels has become increasingly important. However, the impact of external disturbances on ventilating systems has been largely ignored. To address this issue of frequent airflow fluctuations caused by external perturbations, which cannot be fully compensated using conventional control methods, this study proposes a perturbation-compensated ventilation control approach. A disturbance compensator is developed by incorporating the tunnel’s airflow velocity and the number of jet fan start-stop events as input parameters. By compensating for external disturbances, the disturbance to the system is reduced. The Simulink model of the tunnel controller was used for simulation experiments. The compensator demonstrated good tracking results in comparison experiments with different disturbances. The ventilation approach based on disturbance compensator is capable of regulating the fluctuation of CO concentration within a justifiable range compared to using PID control and ADRC. This not only improves the stability of the entire control system but also significantly prolongs the service life of the jet fan by reducing the frequency of start-stop cycles.
