Argentinska Intersection

Situation

Argentinska street is one of the important roads in Prague that connects Bubenské nábřeží with bridge “Barikádníků”. It leads from city centre and other parts of city outside to the northern part of the country, and to Germany or Poland. Moreover, Argentinska street connects hospital “Na Bulovce” with city centre and other parts. For emergency vehicles it is the way how to get faster, where help is needed.

Problem Definition

There is traffic on the road during mornings and evenings, which makes people wait sometimes hours to get out and more important makes difficult pass for emergency vehicles.

Purpose of Simulation

In the scope is part of Argentinska street from Bubenské nábřeží till Dělnická street plus street Za Viaduktem, part of Jateční and part of Tusarova street as they have influence on the whole situation of Argentinska traffic. The purpose of the simulation is to find ways how to make traffic less. In order to do it will be checked, first, if it is possible to change lights more efficiently for cars flow. Second, answer the question – if we can add only one line only to one direction, which direction we have to choose: to city centre or from city centre?

Tool for simulations

For this simulation was used NetLogo 6.0.4. This software is suitable for multi-agent system.

Brief process of simulation

• Data collection. Data will be collected manually (observation) and from HERE traffic API. Manually for morning, midday and evening during 30 mins each part of the day within one week. At the end of data collecting the average distribution will be made based on the data.
• Real situation simulation
• Based on simulation of real situation will be checked the efficiency of lights changes
• The hypothetical model of adding one more line will be created based on simulation of real situation
• Summary

Model

For the purpose of this simulation, the intersections of the streets Argentinska, Delnicka, Jatecni, Tusarova and Za Viaduktem were simulated. World size was set to {{-30,..,30},{-30,..,30}}Where roads are grey, and sidewalks are brown. Roads with determined flows are with arrows of direction. Around roads and sidewalks there are houses and trees. • The cars coming from Argentinska street down (to city center) and then turn right to street Za Viaduktem. • The number of cars going from Delnicka are not that significant, from right flow cars should go up on Argentinska and from left flow should go down on Argentinska. • The cars coming from Argentinska street up (from city center) have four flows. Cars from left flow go left to the street Za Viaduktem. Cars from right flow go left to Jatecni street. Two lines in the middle are going up on Argentinska street. • Then from Argentinska cars can go right first on Tusarova street and go right on Delnicka • This simulation allows the cars to change lines, when it is possible Breeds of the Model: o breed [cars car] o breed[houses house] o breed[trees tree] o breed[crossings crossing] o breed [pedestrians pedestrian] o breed[lightsR lightR] o breed [lightsL lightL] o breed [lightsU lightU] o breed [lightsD lightD] o breed[lightsK lightK] o breed [lightsM lightM] o breed [lightsN lightN] o breed [lightsO lightO]
