magistrsko delo
Abstract
V splošnem je model poenostavljena predstava realnega sveta. Omogoča razumevanje, spreminjanje in ohranjanje lastnosti, napovedovanje ter vplivanje na obnašanje obravnavanega sistema. Z razvojem prometnih modelov se je pojavila možnosti in potreba po modelskem testiranju prometnih razmer in po opazovanju vedenja modeliranih in ne realnih sistemov. Razvoj računalništva je uporabo modelov še podkrepil, kajti merjenje in preizkušanje na terenu, v resničnem okolju, je zelo zahtevno in drago.
V zadnjem času se je pojavila tretja skupina modelov, ki postaja vse bolj uporabna in odpravlja vrzel med makroskopskimi poenostavljenimi in mikroskopskimi podrobnimi modeli. To so mezoskopski simulacijski modeli, ki vključujejo metodo dinamičnega obremenjevanja in so zelo primerni za modeliranje tudi obsežnejših omrežij, kjer se količina prometa v urnih obdobjih spreminja. Prometni udeleženci so opisani zelo podrobno, vendar so njihove medsebojne interakcije definirane na agregirani ravni.
V magistrskem delu je podrobno predstavljen razvoj in možnosti uporabe mezoskopskega prometnega modela, ki temelji na dinamični simulacijski metodi obremenjevanja poimenovani DTA - »Dynamic Traffic Assignment«. V strokovni rabi so mezoskopski modeli pogosto poimenovani DTA modeli.
Namen magistrskega dela je potrditi DTA model kot primerno orodje za analiziranje obsežnih mestnih in primestnih območij ter ostalih urbanih območij kadar potrebujemo natančne podatke glede zamud, izbire poti, potovalne hitrosti itd. V ta namen je narejena primerjava izidov DTA modela in že dobro uveljavljenega podrobnega mikroskopskega simulacijskega modela. V nadaljevanju dela je prikazan razvoj baznega DTA modela za območje Mestne občine Ljubljana in uporaba modela za analizo ukrepov na prometnem omrežju.

Secondary title: |
Development and Application of a Mesoscopic Simulation-Based Dynamic Traffic Assignment Model |
Secondary abstract: |
In general the model is a simplified performance of the real world. It enables understanding, changing and maintaining features, predict and influence the behavior of the system under consideration. Development of transport models makes possible test traffic conditions and observing the behavior of modeled situations rather than build real system. Due to improvement of computer perfomance, model has become more and more usefull for measuring and testing different scenarious. Similar process done in the real environment would be very difficult and expensive.
Lately has appeared the third group of models that are becoming increasingly useful and eliminates the gap between macroscopic and microscopic models. These are mesoscopic simulation models, which include the method of dynamic assignment and are very suitable for modeling large-scale networks where the amount of traffic vary during the day. Traffic users are described in high detail, but their interactions are defined on the lower level versus microsimulation.
The emphasis of work is on development and possible application of mesoscopic traffic model based on dynamic assignment method knows as DTA, which stands for "Dynamic Traffic Assignment." In the professional use of the mesoscopic models often it has been dubbed as the DTA models.
The purpose of the master thesis is confirming DTA model as aplicable traffic modeling tool on urban and suburban large-scale areas, obtain precise information about delays, path, travel time and speed, etc. Practical work consist of comparison the DTA model versus state-of the art microscopic simulation model. Followed by presenting the development of the base year of DTA model for the area of the Municipality of Ljubljana and the aplication on the different network scenarios. |
