“…On one hand, for passenger vehicles, it will undoubtedly provide them with a more fexible and safe driving environment when entering or existing ramps which are prohibited for trucks. Trucks are more aggregated on a limited number of ramps, and the resulting trafc fow distribution may increase the entire performance along freeways [27]. On the other hand, trucks that originally pass through ramps closest to their origins/destinations will have to pass through the adjacent ramps, and the accessibility will be reduced to a certain extent [28].…”

The increasing number of trucks has a negative impact pertinent to efficiency and safety concerns on the operation of mixed traffic flow along freeways, especially at freeway entrance and exit ramps. To address such issue, this study proposes a simulation-based method for truck-prohibit ramp placement along freeways. The method framework contains two parts: the first part is to generate a set of new truck restriction schemes using simulation experiments, and the second part is to evaluate the generated schemes and find out the current optimal location of truck-prohibit ramps based upon the AHP-TOPSIS method. Three patterns of evaluation indicators are utilized to estimate the performance of freeway service in terms of traffic efficiency, road safety, and accessibility. A case study of the Beijing-Hong Kong-Macao freeway within Henan Province, China, is conducted to verify the effectiveness of the proposed method. Results could provide beneficial insights on the optimal location setting of truck-prohibit ramps to enhance the entire performance of mixed traffic flow along freeways.

“…China has an enormous scale of highway bridges in the world and is actively promoting ATP applications under mounting pressure to reduce carbon emissions, while the truck weight regulations are not executed strictly in China. Although studies regarding ATP algorithms [ 6 ], operating control [ 29 ], and application scenarios [ 30 , 31 ] have been carried out in China, the ATP-induced adverse impacts on bridge infrastructures have rarely been studied.…”

Automated truck platooning (ATP) has gained growing attention due to its advantage in reducing fuel consumption and carbon emissions. However, it poses serious challenges to highway bridges due to the load effect of multiple closely spaced heavy-duty trucks on the bridge. In China, ATP also has great application prospects in the massive and ever-increasing highway freight market. Therefore, the load effects of ATP on bridges need to be thoroughly investigated. In this study, typical Chinese highway bridges and trucks were adopted. ATP load models were designed according to the current Chinese road traffic regulations. The load effects of ATP on highway bridges were calculated using the influence line method and evaluated based on the Chinese bridge design specifications. Results show that the load effect of ATP on bridges increases with the increase in the gross vehicle mass and the truck platooning size but decreases with the increasing inter-truck spacing and the critical wheelbase. The Grade-I (best quality standard) highway bridges are generally capable of withstanding the ATP loads, while caution should be exercised for other bridges. Strategies for preventing serious adverse impacts of ATP load on highway bridges are proposed.

“…Understanding the dynamics of how vehicles interact in a platoon allows for the development of advanced technologies and strategies for traffic management. The investigation into platoon-related studies commenced in the 1950s [9], and numerous researchers have documented the application of such studies to reduce fuel consumption and emissions, alleviate traffic congestion, enhance traffic flow, optimize traffic signals, facilitate autonomous driving, and optimize freight and logistics [10]. Taweesilp et al [11] studied the behavior of platoons under various traffic volumes on multi-lane highways, and platoon parameters were employed to evaluate road performance.…”

Vehicle platoon studies are essential for understanding and managing traffic on urban arterial roads. The identification of vehicle platoons on urban roads has drawn more attention in recent years. Researchers have been exploring various methods and algorithms to detect and classify platoons, as well as investigating the benefits and implications of their presence on road capacity, safety, fuel consumption, and environmental pollution. The present study formulated a three-step strategy to identify vehicle platoons in the urban road network under heterogeneous traffic conditions. The proposed three steps are recognizing vehicle interaction, the estimation of critical headway, and vehicle platoon identification. Traffic data were collected for 13 h in a six-lane divided urban arterial road using an infrared sensor. A Python program was developed to recognize vehicle platoons. The results revealed that out of a total of 42,500 vehicles observed, 74% of vehicles were in vehicle platoons. The characteristics of the identified vehicle platoons were studied, thus focusing on key aspects such as platoon size, intra-platoon headway, platoon stream speed, and vehicle composition in the platoon. The results revealed a linear relationship between the percentage of vehicles in the platoon and traffic volume. The findings of the study will be beneficial in examining platoon-based data aggregation, the utilization of road capacity, and traffic flow optimization.
