should government spend more money to improving road and highways, or should governments spend money on improving public transportation (buses,trains,subways)?
Transportation is one of the key factors which help to convert area from rural to urban. It increase communication between two places and it may be country to country, state to state or rural place to urban place. It is mandatory to have a good infrastructure development and proper maintenance of it for having effective transportation. However, we have many sources of transportation, but without good roads it becomes costly.
I think that government should spend more money to improving road and highway, because, we have best facility of transportation like vehicle from reputed company or having good bus service despite there is no use if we haven't proper road. If roads are in bad condition and have so many poth holes, had settled in many area, have not been proper maintained, then it will become a reason for consume more fuel for transportation. Also vehicle reduce its life due to bad road. At the last it will affect on cost of transportation. Increase in consumption of fuel and increase in cost of maintenance of vehicle will hike the price of transportation. Also there are many cause of accident due to bad road. For example, In India NH-8 comes at second rank in heavy traffic in Asia. At the time before a construction of six lane of NH-8, there was big trouble to solve the traffic of that road. Traffic was mostly due to accident, due to distract the vehicle and breakdown the vehicle on road. Now they have made a six lane road and provide big divider between road to prevent vehicle from distracting and if anyone get breakdown then it's easy to give path to other vehicle. Also they have maintained new road from settle down or from poth hole, which gives better access to vehicle with low maintenance and less fuel consumption.
If governments spend more money in improving public transportation rather than in improving road, then public get service with high cost due to reason as explained. So it will not useful for common people to afford that service.
In the conclusion, it is better to spend money to improve road and to maintain it instead of spending in improving public transportation. It will reduce the cost of transportation as well as give fast service because of smooth road.
