Traffic modelling system for cargo transportation at Winter Olympic Games in city of Sochi
For the preparation stage and during Winter Olympic Games in Sochi, the Organizing Committee has arranged for cargo and passenger transportation to be carried out by independent non-profit Transport Directorate of the Olympic Games organisation. In support for automated transportation management, the Transport Directorate placed an order for Automated Management System at the Logistics Transport Center (AMS LTC) in Sochi. The general contractor for the development of AMS LTC was the NIS-GLONASS federal corporation. Mallenom Systems designed, developed and implemented a subsystem for traffic modelling as a part of overall AMS LTC development.
The objective of the traffic modelling subsystem has been stated as following: “Analysis and evaluation of feasibility of strategic and operational plants for transportation, identification of optimal strategies and routes for the cargo transportation to construction sites, depending on the current and projected state of the transport infrastructure”.
Subsystem addresses the main following objectives:
- Development of model for the road network and road traffic flow in Sochi and adjacent areas taking into consideration all types of cargo transport and different types of transportation, characteristics of facilities under construction, warehouses, cargo yards, passenger transport infrastructure.
- Initial data entry and regular model updates. Model calibration in the conditions of constantly changing infrastructure and traffic flow.
- Forecast for multitude of traffic parameters with changing transport infrastructure and cargo delivery routes.
- Evaluation of the logistics system traffic flow capacity under various logistics and traffic management scenarios:
- assessment of the feasibility of operational and long-term plans for cargo transportation of construction materials from cargo yards and warehouses to construction sites taking into consideration the restrictions/limitations of modelled objects of the transport and logistics (restrictions/limitations of the road network, traffic management arrangement, cargo yards and warehouses, cargo transportation vehicles);
- identification of narrow passages in the structure of the simulated objects of the transport and logistics system, which reduce its efficiency in the implementation of cargo traffic plans.
- Development of scenarios for managing the transport and logistics system:
- comparative analysis of the operational plans for vehicle cargo transportation with selection of the most optimal option using wide selection criteria;
- making the recommendations for optimisation of modelling objects of transport and logistics system to improve overall system efficiency for the execution of cargo transport plans, including an identification of the most optimal cargo vehicle routes within the specified transportation plan;
- scenario analysis for the development of proposed traffic conditions within the road network and making recommendations for managing transport and logistics system under the real-world conditions similar to the analysed ones.
Dr Vladimir Tsarev, the director of the project, had the following to say about the project realisation:
“In 2008-2010, we conducted a large-scale research for the development of brand-new traffic modelling system based on the agent-based discrete-event simulation computer modelling technology. We have published a number of research articles covering this topic. We also developed unique software system for traffic modelling named Road Manager and created and implemented pilot commercial sample for hardware-software complex named “Smart traffic light” for adaptive management of a traffic flow. Based on the results obtained by 2011, we were able to convince the representatives of general contractor and organisation that placed the original order that our developed technologies have great potential for successful completion of specified tasks. As a result, we got involved in the project and began the design and implementation of the traffic modelling subsystem based on our Road Manager system. In 2012 this subsystem was integrated at AMS LTC in Sochi and put into commercial operation.”
