Functional Specifications of Multilevel Highway
People reason hierarchically when they navigate highway networks. The hierarchical structure is induced by a sequence of tasks starting with route planning, continuing with wayfinding instructions, and leading to the actual driving process. In order to perform adequately, people need to map highway features and navigation actions from one task level to the next. What exactly are these features,...
متن کاملApplication of Neural Network in the Cost Estimation of Highway Engineering
Based on the BP neural network, this paper sets up the model of cost estimation of highway engineering. The BP neural network model is trained by a sample data obtained from some performed typical engineering to come true quick cost-estimating.It is sure that the method is practical and the estimating results are reliable according to lots of examples.It shows the promising perspective of BP Ne...
متن کاملUsing Hybrid Fuzzy PROMETHEE II and Fuzzy Binary Goal Programming for Risk Ranking: A Case Study of Highway Construction Projects
Multi attribute decision making methods are considered as one of the most useful methods for solving ranking problems. In some decision making problems, while the alternatives for corresponding criteria are compared in a pairwise comparison manner, if the criteria are inherently fuzzy, debates will arise in ranking alternatives due to the closeness of the values of the criteria. In this researc...
متن کاملComparative Research on Optimal Damping Matching of Seat System for an off-Highway Dump Truck
To protect the driver of off-highway dump trucks from the harmful vibration, this paper presents the comparison results to determine the optimal damping of the seat system by different optimization design plans. Three optimization schemes are considered including individually optimizing the damping of the cushion, individually optimizing the damping of the seat suspension, and integrately optim...
متن کاملAn Investigation on the Parameters Influencing the Pounding in Highway Bridges
The present aim of this study is to investigate the effect of different parameters influencing pounding in highway bridges. Pounding is the result of a collision between two parts of the deck and/or the deck and abutments at the separation distance during the earthquake. In the present study, the period ratio of the adjacent frames, ground motion spatial variation, and soil-structure interacti...
