The existing intelligent vehicle trajectory-planning methods have limitations in terms of efficiency and safety. To overcome these limitations, this paper proposes an automatic driving method based on a variable Gaussian safety field. Firstly, the time series bird’s-eye view is used as input state quantity network, which improves effectiveness trajectory planning policy network extracting featu...

The assessment and grading of a highway landscape environment is the basic work route layout planning, it also key link to whether can be integrated into surrounding environment. This article analyzes connotation value standard system proposes method that combines quantitative humanistic assessment. Consequently, indicator with features, environmental harmony, visual carrying capacity as conten...

Movement analytics and mobility insights play a crucial role in urban planning transportation management. The plethora of data sources, such as GPS trajectories, poses new challenges opportunities for understanding predicting movement patterns. In this study, we predict highway speed using gated recurrent unit (GRU) neural network. Based on statistical models, previous approaches suffer from th...

Highway systems play a key role in providing mobility to society, especially during emergency situations, including earthquakes. Bridges highway are susceptible damage from earthquakes, causing traffic capacity loss leading serious impact on surrounding areas. To better prepare for such scenarios, it is important estimate and disruptions For this purpose, traffic-capacity-analysisbased methodol...

to properly plan for construction, repair, maintenance, and reconstruction of highways the minimum acceptable roadway condition is needed information. this, along with other pavement management tools, will help select the most desirable roadway alternatives. in this research the minimum acceptable conditions are developed based on an opinion survey of non-technical but high-level decision maker...

Highway infrastructure construction is regarded as one of the effective policy tools used to promote flow production factors and upgrade industrial structure in China, it may also be an important precondition improving Cultivated Land Use Efficiency (CLUE). This paper uses a slack-based model (SBM) based on provincial-level panel data from China 2004 2017 measure CLUE. Then dynamic spatial Durb...
