Resumen
MODELS THAT PREDICT THE OPERATING SPEED IN TERMS OF HIGHWAY GEOMETRY ASSUME THAT DRIVERS ARE HOMOGENOUS INDIVIDUALS. HOWEVER, ROAD USERS BUILD THE WAY THEY DRIVE BASED ON THEIR BEHAVIOR AND SKILLS, THEREBY CONFIGURING THE SO-CALLED DRIVING STYLE. THE STATE-OF-THE-ART LITERATURE DEFINES AT LEAST EIGHT DRIVING STYLES THAT AFFECT THE OPERATING SPEED OF DRIVERS. THE OPERATING SPEED-GEOMETRY MODELS DO NOT CONSIDER THIS ASPECT. THE PURPOSE OF THIS PAPER IS STUDY THE EFFECT OF DRIVING STYLES ON THE OPERATING SPEED IN CREST VERTICAL CURVES OF TWO-WAY ROADWAYS. THEREFORE, 16 DRIVERS WERE SELECTED AND CLASSIFIED ACCORDING TO THEIR DRIVING STYLE, BASED ON THE MULTIDIMENSIONAL DRIVING STYLE INVENTORY (MDSI). SUBSEQUENTLY, THE CIRCULATION SPEED OF EACH DRIVER WAS TESTED ON 40 CREST VERTICAL CURVES THROUGH A GPS LOGGER OF 10 HZ INSTALLED IN EACH VEHICLE. NEW OPERATING SPEED-VERTICAL GEOMETRY MODELS WERE DEVELOPED AND CLASSIFIED BY DRIVING STYLES. IT WAS CONCLUDED THAT MODELS THAT DO NOT CONSIDER DRIVING STYLES CONCEAL THE SENSITIVITY OF THE OPERATING SPEED TO THE VERTICAL GEOMETRY OF HIGHWAYS. ADDITIONALLY, AMONG THE DIFFERENT DRIVING STYLES THERE IS AN OPERATING SPEED DIFFERENCE OF UP TO 8 KM/H. THEREFORE, INCLUDING THE DRIVING STYLE VARIABLE IN OPERATING SPEED MODELS OF TWO-WAY ROADWAYS IS A RELEVANT FACTOR.
