​Financial stability is the cornerstone of modern economies and shows the proper functioning of the financial system and is a prerequisite for economic growth and strengthening the economy against shocks. In the path of economic growth and development, financial stability and its effects play an important role in the economy. On the other hand, road transportation is one of the important sectors of the country's economy and has a great impact on the country's economic growth. So, considering the importance and role of financial and economic stability in increasing the country's economic growth, as well as the importance of road transportation in the country's economy, in this study, the analysis of short-term and long-term causality relationships between the financial and economic stability index and the economic growth of the investigated road transport sector is included. For this purpose, first, the combined financial and economic stability indices were calculated, and then the short-term and long-term causal relationships between the financial and economic stability index and the economic growth of the road transport sector were analyzed. The results indicate a long-term and short-term relationship between the growth of the combined indicators of financial and economic stability and the value-added growth of the road transport sector, the growth of the amount of goods carried and the growth of the amount of passengers carried in the road transport sector. The effect of combined indicators of financial and economic stability on the added value of the road transport sector, the growth of goods transportation and the growth of passenger transportation has been positive. There is a one-way causal relationship from the combined indicators of financial and economic stability to the added value of the road transport sector, the increase in the amount of goods transported and the growth in the amount of passenger transportation.

The transportation sector includes activities that are widely effective in the processes of production distribution and consumption of goods and services. so, it plays a fundamental role in the economic growth of countries. However, investment in transportation infrastructure despite the positive effects, may not have maximum effects on growth in developing countries due to mismanagement and lack of proper strategy and plan in infrastructure development. As a result, considering the nature of investment in the transportation sectorm this sector and the growth of the national GDP from different dimensions and angles becomes more important. The current research has investigated this issue based on a "vector error correction model" and its estimation in the period from 1373 to 1399. the relationships of the variables used in this model can be specified in the form of three correlation relationships. These three relationships can be examined under the three relationships explaining real GDP, real exchange rate and real investment in the transportation sector, which respectively describe the behavior of the real sector of the economy, the behavior of the currency market and the behavior of investment in the transportation sector. According to the obtained results, the variable of investment in the transportation sector has an effect on the production variable in the long term, and the extent of this influence is such that each one percent increase in the real investment in the transportation sector can be 0.09 percent in growth Iran's economy will be effective.
