Thailand's road system compares favorably with that of other developing countries in the region. Transport of goods and passenger services by rail, sea, air and road generally is good. Major inter-city links are being expanded into four or more lane highways. Rural roads are being improved. Expressways, highways and mass transit infrastructure are all in the works, but during their construction period, they are actually making the situation worse in traffic, pollution and safety.
Road transportation is considered Thailand's key transportation mode for goods and passengers.
Because of the cash shortfalls due to the economic crisis, completion dates for several mass transit systems, including the sky train and the subway have been delayed. The contract was finally canceled by the government which is now looking at restructuring options. A rail route from Rayong to the Eastern Seaboard Development Project to Bangkok is being studied and designs evaluated. Because rail development is needed, the State Railway of Thailand, when RTG budget becomes available, will accelerate implementation of its planned 800 kilometers double-track construction project. Thailand has coastlines on the Gulf of Thailand and on Andaman Sea with 58 sea channels, forty operational seaports and ninety fishing trawler piers.
