The impact of road transport on the growth of gross domestic product : case study of Tunisia

Abstract EN

Many countries tend to focus on road transport as one of the most important sectors affecting economic growth.

This study comes to answer the following problem: How the impact of land transport vehicles on GDP could be understood? To answer this problem, descriptive and analytical methods were used.

This study aims to analyze the impact of road transport (freight and passenger transport) on Tunisia's Gross Domestic Product during the period 2005-2017.

Based on GDP and the size of road transport vehicles in Tunisia, The study uses the simple linear regression method.

The study suggests three main results: 1.

The best case for the Tunisian economy is to increase its freight transport vehicles within an industry-based economy.

2.

The worst case to be avoided is to increase its passengers transport vehicles within a service-based economy.

3.

The more freight transport vehicles in a multi-sectorial Tunisian economy, the better the impact would be on GDP, when comparing the best and worst case scenarios.
