Evaluation of Rural Road Traffic Safety in Loess Plateau Gully Area of China

Sustainability, Journal Year: 2025, Volume and Issue: 17(2), P. 721 - 721

Published: Jan. 17, 2025

In order to solve the safety ambiguity problems in construction and use of rural roads gully area Loess Plateau, this paper proposes a assessment method based on normal cloud model (NCM). First, index system is constructed by combining key features road traffic safety, weight coefficients each are determined entropy (EWM) set criteria. Then, eigenvalue indicator calculated using clarify degree its affiliation different levels, which fully reflects randomness process. Finally, selects typical Plateau for example analysis. The results show that not only reduces subjective influence evaluation criteria, effectively solves problem ambiguity, provides reliable scientific basis improving but also lessons references improvement transportation other similar areas; improves security capacity service level regional roads; meets needs masses safe comfortable travel; enhances people’s sense well-being, accessibility, security; boosts development; better promotes optimization even nationwide services quality.

Multiobjective Optimization of the Economic Efficiency of Biodegradable Plastic Products: Carbon Emissions and Analysis of Geographical Advantages for Production Capacity

Sustainability, Journal Year: 2025, Volume and Issue: 17(7), P. 2874 - 2874

Published: March 24, 2025

The objective of this study was to address the limitations biodegradable plastics—low economic benefits and marketing difficulties. To end, analyzed production processes two plastics: polylactic acid (PLA) polybutylene adipate terephthalate (PBAT). Based on analysis, economic, technical, environmental improvement indicators were constructed, an optimization model with three objectives profit, carbon emission cost, process risk established. In study, we embedded improved NSGA-III algorithm obtain Pareto optimal solution set. We also proposed entropy-weighted efficiency index (EWEI) for analysis transport advantages based distribution plastics production, road density, regional prices. With a line capacity 10,000 tons 8% discount rate, 10-year return PBAT products 7,039,931.23 yuan higher than that PLA products. profit 488.92 per ton production. However, exhibited carbon-emission cost products, especially risk, by 0.11%. East China region has obvious geographical advantages, but Southwest is constrained in presence mountainous terrain. Therefore, it imperative optimize China’s overall industrial layout plastics, strengthen acquisition support sustainable promotion market, effectively minimize pollution caused traditional plastics.

Traffic Flow Prediction Framework That Can Appropriately Process the Noise, Volatility, and Nonlinearity in Traffic Flow Data

International Journal of Intelligent Systems, Journal Year: 2025, Volume and Issue: 2025(1)

Published: Jan. 1, 2025

Accurate traffic flow prediction is crucial for improving transportation efficiency. To improve the accuracy of prediction, we developed a framework—namely, multicomponent network—that appropriately processes noise, volatility, and nonlinearity in data. This framework comprises three components: factor selection component, decomposition component. The component considers dynamic effects weather‐related, environmental, spatiotemporal factors on flow; it then extracts analyzes exhibiting strong correlations with flow. optimizes parameters variational mode basis envelope entropy by using sparrow search algorithm; transforms into multiple intrinsic functions to enable accurate prediction. Finally, constructs feature matrices bidirectional gated recurrent unit model identify relationships within Moreover, uses an attention mechanism assign different weights features importance these thereby enabling efficient processing large volume performance proposed was examined experiments conducted volumes data time granularities. results indicated that achieved high stability various granularities, samples, dataset sizes, noise conditions. generally outperformed existing models under all experimental
