In my own opinion it is yes, fast transportation makes economic turnover faster because when the goods and the people move quickly and efficiently it could have a positive impact on the economy. Fast transportation can reduce the time and cost of moving productivity and efficiency, as businesses can receive necessary supplies and materials more quickly. It can also increase the speed at which products are delivered to customers, which can improve customer satisfaction and loyalty. Fast transportation can also improve access to the markets. It can attract more businesses and investors which in return it can create more jobs and increase economic growth.
Yes you are right, but let's be real if you also have the money to buy some vehicle for your own convenient you would buy right? Here in my country in the PH, which is traffic is the common issue in the community since it affects a lot of people's job. It took a lot of time for them imagine a deduction to you for being late then the salary of an average person is bare minimum. They have no choice but to use public transportation still traffic would be a problem. I've already said this imagine 10 people owning 10 vehicles instead of using 1 bus that could contain a lot of passengers. What's more convenient for the road? Of course 1 vehicle.
Indeed, if calculated 1 person has a vehicle will make a narrow and efficiency road will be reduced because it accumulates in congestion, in my opinion not on the vehicle but there are regulations on the use of vehicles, road services, and traffic regulations in your country, if your country has traffic rules which is systematic, for example for public transportation more priority or built road lanes only for public transportation (not personal) then the target to work you will be more efficient, because usually what makes traffic jams is a public transportation that is waiting for passengers, and if you want more Good and more efficient, the departure of the bus stop must have a regular schedule, so everyone has a calculation when he is waiting at the bus stop.
I agree that fast transportation will find rapid economic growth because activities will be more efficient, but indeed in this problem it also needs adequate infrastructure and regulations to the expected point of efficiency to accelerate economic growth.
