Transportation systems are constantly degrading, and the extent to which this has occurred in the United States has caused a great deal of alarm. There is a growing need for alternative transit that does not involve automobiles. The Bureau of Labor Statistics reported that the average salary of a transportation planner was $56,000 per year, with the top 10 percent earning more than $86,880 a year. Job security is excellent, as transportation is integral to the functioning of society, and society grows ever-more mobile. Working for the government provides even greater security, and around 68 percent of planners are so employed. More emphasis is now placed on rail networks.
