Abstract

With suitable algorithms, it is possible to ascertain a certain spatiotemporal logic for a given area by combining cellular and vehicular data. This thesis proposes a set of methods that aim to estimate trajectories of sparse cellular data by reconstructing a road network using the Floating Car Data (FCD). Thenceforth, generating a pool of alternative paths of the reconstructed network with a shortest-path algorithm and conclusively computing an algorithm that allocates the user an alternative... More route with the highest spatial and temporal similarity to the observed ground-truth origin-destination pair (user) trajectory. With the data on the user trajectories used through a transportation network, this thesis aims to develop a model which calculates the networks traffic flow estimates. Less

Abstract (croatian)

Pomoću prikladnih algoritama, moguće je utvrditi određenu prostorno-vremensku zakonitost prometnog toka obuhvaćenog područja kombiniranjem podataka o celularnoj mreži i povijesnih zapisa kretanja vozila. U ovom se radu predlaže skup metoda kojima je cilj procijeniti putanje kretanja korisnika celularne mreže rekonstrukcijom cestovne mreže pomoću plutajućih podataka o vozilu (FCD). Nadalje, nad rekonstruiranom cestovnom mrežom se izvršava algoritam najkraćeg puta te se generira n alternativnih... More trajektorija. Konačni korak procjene trajektorije predstavlja izvršavanje algoritma koji korisniku dodjeljuje alternativni put s najvećom prostornom i vremenskom sličnošću s promatranim parom ishodišno-odredišne putanje korisnika. Pomoću podataka o korisničkim putanjama korištenim kroz prometnu mrežu, ovaj rad teži razviti model koji izračunava procjene protoka prometa na mreži. Less
