heal.abstract | Αναλύθηκαν οι κανονισμοί για τον υπολογισμό του απαιτούμενου μήκους ορατότητας για προσπέραση και στη συνέχεια δημιουργήσαμε το δικό μας μαθηματικό τύπου υπολογισμού αυτού του μήκους με βάση διάφορες παραμέτρους, Με βάση αυτό το μοντέλο εξετάσθηκαν δύο τύποι οδών με διάφορες κατά μήκος κλίσεις, μέσω του λογισμικού οδοποιίας "FM16". Έτσι, δημιουργήθηκαν τα αντίστοιχα διαγράμματα ορατότητας για να ελεγχθεί η επάρκεια προσπέρασης. | el |
heal.abstract | This diploma thesis aims at creating a mathematical equation that will calculate the required length of visibility for overtaking at any point of any single traffic path, taking into account the parameters that affect it. Through this type it will be possi ble to check the adequacy of any length given. Initially, through the bibliographic review, the criteria for checking a visibility pathway were identified and recorded in accordance with applicable regulations. Subsequently, a mathematical model was develo ped that calculates the required visibility for overtaking for a given speed and slope. It has been found that the main parameters that affect the problem are vehicle speeds, overtaking times, overtaking and safety procedures between vehicles as well as th e longitudinal slope through acceleration. Through the "FM16" software, which calculates existing visibility, two street case studies, one with maximum longitudinal slopes and one with standard range gradients, were examined. The results and outcomes that emerged, analyzed and compared with the corresponding results extracted from the mathematical formula. The main conclusion of this work was that the two - dimensional method is not sufficient to analyze the problem, since the co - existence of horizons and cro ss - sections can significantly affect the length of visibility for overtaking. For this reason, it is proposed to use the three - dimensional method for analytical computation and proficiency testing, while the two - dimensional method for extracting quick and inexpensive conclusions. | en |
