Parameters Affecting the Determination of the Tunnel Threshold-Zone Luminance
Threshold-zone luminance Visual ability Duration time Perception probability Safe stopping
2009/10/14
In order to determine the level of the tunnel threshold-zone luminance, as series of visual experiments were conducted using a tunnel entrance simulator. For the experiments 110 observers were used. T...
Determination and Evaluation of Traffic Congestion Costs
Determination Evaluation Traffic Congestion Costs
2009/9/28
The current estimation of time loss and costs of traffic congestion is lacking a scientifically valid empirical database concering the queue speed and time loss, as well as a methodological soundness ...
Determination of traffic flow parameters in different traffic flow interaction cases
traffic flow kinetic theory modelling characteristic method
2007/9/1
Modelling of straight road section consisting of one traffic line gives the opportunity to simulate “follow the car” system. In general it looks like a line of vehicles, going one after another. Kinet...
Determination of optimal work start time
optimal work start time stochastic dynamic simultaneous route/departure time equilibrium
2007/3/1
The question is: whether the system total travel cost and travel time are reduced by adjusting the work start time or not? This paper proposes the two-level model for answering the question; the upper...
Determination of the angles of pressure in the system of limitation by optimisation of linkages
speed acceleration force equation angle of pressure
2006/12/1
In the present paper a method of analytical determination of reactions and angles of pressure is considered with the four-bar linkage as an example. The determined sequence for the expression of accel...
Determination of extreme train running parameters along a railway line segment
train running optimization train-car parameters energy consumption
2006/6/1
It is possible to select train-car draft mass and traction vehicle parameters for technical speed along segment in such a way that unitary total energy consumption related to train-car mass would be...
Determination and evaluation of the factors of outsourcing logistics
logistic outsourcing warehousing transportation
2006/3/1
This paper focuses on the determination and evaluation of the factors of logistic outsourcing. Many authors usually talk about logistics service outsourcing and its reasons and benefits as well, but i...
Determination of car run up – braking and manoeuvring parameters in an emergency situation in the case of limited road segment
run up braking manoeuvre time distance road accident
2005/8/31
As the traffic intensity on roads increases, the number of road accidents also increases and the situations become more and more complicated. The presented method of reconstruction of preaccidental si...
The determination of the endogenous market penetration and compliance rate of advanced traveler information systems
advanced traveler information systems market penetration compliance rate nested logit model
2004/8/31
We consider a specific ATIS which objective is to reduce drivers’ travel cost uncertainty with recurrent network congestion through the provision of traffic information. Most of the studies premise of...
The determination of a complex criterion for assessing the performance of traction rolling stocks
locomotive diesel trains rolling stocks
2004/4/30
For assessing the quality of rolling stocks, the research was made into the operational expenses aimed to derive their relation with the time of rolling stock operation which could be used as a basis ...
Quality control on the basis of entropy determination
statistical methods entropy quality deviations organization complex system quality control
2004/4/30
Statistical methods are extensively used in quality control. The method of the application of entropy conception for quality control is proposed. It is based on the use of statistical information abou...
The application of a fuzzy algorithm for the determination of the shortest chain to correct disorganized train traffic
traffic control railway mathematical model shortest chain uncertainty algorithm
2003/6/30
The problem of the correction of the disorganized train traffic schedule is analyzed (aiming to minimize general costs related to the expenditure of energy and time wasted by people and equipment). Di...
