Założenia modelu decyzyjnego doboru usług ITS w celu eliminacji zakłóceń potoków ruchu

Karoń G., Żochowska R.

Prace Naukowe Politechniki Warszawskiej. Transport

2018

z. 120

167--177

W artykule przedstawiono podstawowe założenia modelu decyzyjnego, dotyczącego doboru usług ITS, w celu łagodzenia i eliminacji negatywnych skutków zakłóceń potoków ruchu w sieciach transportowych. W pierwszej części przedstawiono strukturę systemów ITS, z uwzględnieniem usług systemów kooperujących C-ITS oraz wybranych strategii sterowania i zarządzania ruchem. W drugiej części sformułowano uogólniony opis formalny modelu decyzyjnego doboru konfiguracji funkcjonalno-użytkowej ITS dla określonych miar zakłóceń potoków ruchu.

The article presents the basic assumptions of the decision-making model regarding the selection of ITS services in order to mitigate and eliminate the negative effects of disruptions to traffic flows in transport networks. The first part of article presents the structure of ITS systems, including cooperative systems C-ITS, and selected strategies for control and traffic management. The second part of article formulates a basic formal description of the decision-making model for the selection of ITS functional configuration for specific measures of traffic flow disturbances.

Structure of transport model on strategic level of management for assessment of its configuration

Karoń G., Mikulski J.

Journal of KONES

2017

Vol. 24, No. 3

119--126

The aim of the article is to present the issues related to the use of the transport model for ex-ante evaluation of the functional and operational configuration of ITS. Variants of ITS configuration have been presented based with use of ITS user needs from FRAME methodology and with use of ITS user services implemented in cities of Poland. The structure of the transport model on strategic level of traffic management has been presented in the context of the following impact of ITS configuration: changes in the use of paths in network, changes in the use of transport system modes, changes in the destinations of trips, and changes in the number of trips for various purposes. The results of transport model enable a comparison, using an incremental method, results of transport decisions of users, obtained in specified forecast horizons for the ITS variants of configuration. Structure of transport model presented in article is suitable for strategic level of traffic management with long-term results. While transport models for tactical level of traffic management with medium-term results, and for operational level of traffic management with short-term results are used to determine the characteristics, describing traffic conditions in a transport network, for example expected smoothness of traffic flows, and to determine dynamic characteristics describing for example information spread processes in dynamic traffic networks.
