In the last few years Wireless Vehicular networks have been in the limelight for their potential in many human applications such Road Safety, Info-Mobility, Infotainment, Environmental Monitoring, etc. The research community responded to the new emerging needs designing a number of applications, algorithms, and protocols to cope with the vehicular environment. Differently from tactical ad hoc n...

Despite recent progress for vehicular communication in research, development, field tests, and standardization, security is still in an early phase though it represents a crucial part of the vehicular communication system. So far, no vehicular security architecture has been proposed which integrates existing individual solutions for vehicle registration, data integrity, authentication, and so o...

Vehicular traffic simulations are useful in applications such as emergency planning and traffic management, for rapid response and resilience. Here, a parallel traffic simulation approach is presented that reduces the time for simulating emergency vehicular traffic scenarios. We use a reverse computation-based optimistic execution approach to parallel execution of microscopic, vehicular-level m...

Vehicular emission is an important source of air pollutants in urban cities in the Pearl River Delta (PRD) region of South China. In order to study the impact of evaporative loss of vehicular fuel on air quality, several commonly used fuel samples were collected in four main cities in the PRD region – Hong Kong, Guangzhou, Macau and Zhuhai, and analyzed for their volatile organic compounds (VOC...

This article provides a panorama on the security in vehicular networks’ environments. The special characteristics of these environments are presented and a general classification for the different types of attacks illustrated by some relevant attacks examples is introduced. Consequently, some key security requirements and security challenges are derived, considering Intelligent Transportation S...

Vehicular ad-hoc networks have gained a significant attention during the last decades from the industry and academia with the goals of increasing road safety and traffic management among others. However, vehicles are normally constrained by resources, including computation, storage, and radio spectrum bandwidth. Many emerging applications demand complex computation and large storage, including ...

Abstract The COVID-19 pandemic and ensuing lockdown of many US States resulted in rapid changes to motor vehicle traffic their associated emissions. This presents a challenge for air quality modelling forecasting during this period, that transportation emission inventories need be updated near real-time. Here, we update the previously developed fuel-based inventory emissions (FIVE) account due ...

Being a derivative of the famous IEEE 802.11 family of standards [1], which was originally targeted at indoor wireless communication, the IEEE 802.11p amendment for vehicular communication [2] still bears certain assumptions about the wireless channel which do not apply for vehicular scenarios. As IEEE standardization is finished, international harmonization of local standards is already on the...

The review of major 3-D global and regional real-time air quality forecasting (RT-AQF) models in Part I identifies several areas of improvement in meteorological forecasts, chemical inputs, and model treatments of atmospheric physical, dynamic, and chemical processes. Part II highlights several recent scientific advances in some of these areas that can be incorporated into RT-AQF models to addr...
