“…Highways are crucial for fast transportation, promoting regional economic development, and enhancing intercity connections by facilitating efficient movement of goods and materials (Bian & Yeh, 2020). However, the rapid construction of highways has also led to environmental issues such as ecological degradation (Mohammadi & Fatemizadeh, 2021;Hz et al, 2020;Li and Banerjee, 2021;Basu et al, 2021), landscape damage (Hu et al, 2023;Gong et al, 2021), and significant carbon dioxide emissions Dong et al, 2024;.…”

Efficient vegetation planting is essential in highway construction to reduce greenhouse gas emissions and prevent ecological degradation. However, carbon sequestration has rarely been considered in previous optimization models for planting strategies in these environments. To address this gap, this study focuses on selecting five predominant shrub species—Ailanthus altissima, Robinia pseudoacacia, Vitex negundo var. heterophylla, Amorpha fruticosa, and Lespedeza bicolor—typical of the Linyi section of the Beijing-Shanghai Expressway. The study quantifies the carbon sequestration rates and water consumption of these species to demonstrate their contribution to climate change mitigation. Field data were collected in spring, summer, and autumn using the LI-6800 portable photosynthetic system. The NSGA-II was subsequently adopted to establish an optimal model, considering constraints of a planting area of 1000 m² and a water consumption limit of 1067.9 mm. Based on the recorded datasets and the implementation of NSGA-II, the optimized vegetation planting structure for this area comprised Ailanthus altissima (21%), Robinia pseudoacacia (30%), Vitex negundo var. heterophylla (11%), Amorpha fruticosa (26%), and Lespedeza bicolor (12%). By adopting this novel solution, the carbon sequestration capacity per square kilometer increased by 541 kg, while water consumption decreased by 104 mm. This manuscript exemplifies achieving a balance between ecological and economic benefits through an optimized and targeted vegetation planting structure on highway slopes. Local and national authorities can use these results to implement similar strategies in different areas.

The carbon emitted by vehicles traveling on curved roads is greatly affected by the alignment of the route, yet the mechanism behind this is not yet clear, leading to current horizontal alignment designs being unable to avoid this problem. To clarify the principles and indicator thresholds of low-carbon design for planar geometry, this study takes the carbon emission of traveling on curved routes as the research object, and establishes a relationship model between carbon emissions and design indicators based on the principles of vehicle dynamics and kinematics. Field tests were conducted to validate the quantitative relationship model. The model shows that both radius and superelevation are negatively correlated with carbon emissions, while the lateral force coefficient is positively correlated with carbon emissions. The contribution of radius to carbon emissions is greater than that of superelevation. This study clarifies the recommended values of low-carbon design indicators by assessing carbon emissions according to the current route design specification, outlines the principles of superelevation settings, and proposes a methodology to deal with the relationship between superelevation and the lateral friction coefficient. The research findings promote the quantification and standardization of low-carbon highway design, contributing to the early mitigation of high-carbon emissions from curved traffic during the design phase.
