Decision Supporting Model for Highway Maintenance

A decision model for pavement management has been developed herein based on linear programming formulation. Markov transition probability matrices are introduced to model the deterioration process of the road sections. To every type of road surfaces and class of traffic amount belongs a certain Markov matrix. The presented model and methodology is used to determine the optimal rehabilitation an...

Live load model for highway bridges *

Load models are developed for highway bridges. The models are based on the available statistical data on dead load, truck loads and dynamic loads. The paper deals mostly with the static live load. The model is derived from truck surveys, weigh-in-motion measurements and other observations. Simple span moments, shears and negative moments are calculated for various spans. Extreme 75 year loads a...

Highway-LSTM and Recurrent Highway Networks for Speech Recognition

Recently, very deep networks, with as many as hundreds of layers, have shown great success in image classification tasks. One key component that has enabled such deep models is the use of “skip connections”, including either residual or highway connections, to alleviate the vanishing and exploding gradient problems. While these connections have been explored for speech, they have mainly been ex...

Performance evaluation of highway mobile infostation networks

A mobile infostation network stipulates all transmissions to occur when nodes are in proximity. In this paper, we evaluate the effect of mobility on highway mobile infostation networks. Each node enters a highway section at a Poisson rate with a constant speed drawn from a known but arbitrary distribution. Both forward and backward traffic are considered. For node speed that is uniformly distri...
