Safety Comparison of Simple and Spiral Horizontal Curves Based on Side Friction Factor Dynamic Modeling
نویسندگان
چکیده
A horizontal curve’s geometric design is considered an important factor in highway accidents, and simple spiral curves are regarded as the most common types of curves. Various factors affect safety curves, one which side friction Therefore, this study, was investigated for E-class sedan, SUV, two-axle conventional truck based on factor. In regard, CarSim TruckSim vehicle dynamic simulation software were utilized using 360 scenarios, including speed, type, curve radius, road geometry. It revealed that maximum all vehicles higher than curve. Also, process increasing carried out with a gentler slope Except radius 0.7 times (R) radii R 0.9 sedan lower AASHTO recommended values, shows better safer compared to

Geometric design safety estimation based on tire–road side friction
A closed-loop drive–vehicle–road–environment system (DVRES) model was established using Adams/Car and Matlab/Simulink. Dynamic responses of lateral tire forces based on tire–road side friction and road geometric characteristics are used to investigate vehicle side slip for geometric design safety estimation. The root mean square, the maximum values of lateral tire forces, comfort limit on curve...

the rationale behind the present study is that particular learning strategies produce more effective results when applied together. the present study tried to investigate the efficiency of the semantic-context strategy alone with a technique called, keyword method. to clarify the point, the current study seeked to find answer to the following question: are the keyword and semantic-context metho...
15 صفحه اولFactor-based comparison of groups of curves
A method able to detect a possible common structure between two (or more than two) groups of curves is considered. This technique is part of the recent developments within the field of Functional Data Analysis. It is discussed how the standard approach based on factorial analysis for comparing groups of multivariate data can be used in this infinite-dimensional framework. The potentiality of su...
متن کاملFriction modeling for dynamic system simulation
Friction is a very complicated phenomenon arising at the contact of surfaces. Experiments indicate a functional dependence upon a large variety of parameters, including sliding speed, acceleration, critical sliding distance, temperature, normal load, humidity, surface preparation, and, of course, material combination. In many engineering applications, the success of models in predicting experim...
متن کاملsafety evaluation of highway geometric design criteria in horizontal curves at downgrades
the previous studies show that a high percentage of traffic accidents take place in two-lane rural highways and most of which happen at horizontal curves. meanwhile the horizontal alignment is often subject to hard topographic conditions where because of economic aspects designers are forced to design horizontal curves at grades. vertical angle of longitudinal slope reduces the normal force of ...
