Abstract. There is always need for a good simulation for traffic in Vietnam in order to help transportation planners to improve the current traffic system. Over recent days, there has been severe traffic congestion in many streets of big cities in Vietnam such as Hanoi and HoChiMinh city. There is an urgent need for measures to deal with increasing congestions. The simulation of traffic in Vietnam is a hard problem due to two main reasons including: (1) the traffic participants in Vietnam do not give way according to the rule; (2) the participants do not consider that when waiting for the vehicles in front, stopping in the intersection is obstructing the traffic flow. In this paper, we propose a multi-agent based simulation system for traffic in Vietnam to help transportation planners to find treatments to the problem of congestion of the traffic system in Vietnam as well as to test new designs before committing resources to actually building the transportation infrastructure. By allowing a user to design different road systems as well as to create different simulation scenarios with different agent profiles, our system can simulate the dynamic of traffic in Vietnam in different situations.

Introduction

For all countries, transportation is one major part of infrastructure, which has a direct impact on the economic and social development of the country. However, building a good transportation system is always a difficult problem for every country in the world. In developed countries, the development of transportation system always requires huge expenses. In addition, transportation planners always have to have a strategic vision, which can identify a clear plan to develop the transport system. In Vietnam, transport infrastructure does not keep up with the social and economic development, thus obstructing the modernisation and industrialisation of the country. Currently in Vietnam, traffic is a sore issue for policy makers. In cities such as Hanoi, the transport system is chaotic, due to narrow road, increasing number of vehicles, and lack of consciousness to follow the traffic rules from participants. The result is an increase in congestion, accidents and environmental pollution. So the search for solutions to develop transport systems in Vietnam is still a challenging question.

In many countries, the traffic simulation system on a computer has long been studied for finding and evaluating solutions to develop transport systems [1, 2, 4, 7, 8, 9, 10, 11]. Before blocking a road, opening a new route or timing the green light and red light in the real world, the developers can test the system in the simulation system. Either for the purpose of modeling short-term traffic dynamic on a single road section or for transportation planning describing behavioral pattern in a network on a larger time scale, existing simulation systems often assume that the behaviour of drivers involves accelerating, braking, and changing lanes. This results in a range of methods from mathematical models, macroscopic models to nanoscopic models [5].

The traffic in Vietnam, however, is difficult to model due to the more complicated behaviour of drivers. As the drivers do not follow the lanes, the traffic simulation becomes closer to the crowd simulation. Therefore, mathematical models or macroscopic models are difficult to obtain in this case. Instead, microscopic models are more suitable. In this paper, we propose a microscopic approach of using multi-agent based simulation for the traffic in Vietnam. The driving behaviour of an agent in our system is characterized by different parameters such as planning time, maximum speed, and acceleration rate. By allowing a user to design different road systems as well as to create different simulation scenarios with...
