Using visum traffic simulation model to evaluate the traffic network on the economic corridor: Lao Cai – Hanoi – Hai Phong – Quang Ninh

The Lao Cai - Hanoi - Hai Phong - Quang Ninh economic corridor is an important transport axis linking Southwest China with the northern provinces of Vietnam. At the same time, the corridor is a bridge connecting this area to the world. In this paper, the authors uses the traffic simulation tool PTV VISUM to build a traffic network in the corridor area. Use the model to make preliminary assessments of factors affecting the corridor traffic network in different development scenarios, especially directions for developing multi-modal transport combined with inland waterways, railways and roads. The study also evaluated the effectiveness of a number of key projects on the corridor in terms of economics, minimizing traffic congestion, reducing environmental pollution, etc. The paper also gives some recommendations for development this economic corridor.
