Quietly, the bus industry has made come back for consumers travel options.

Here’s more from the Manhattan Institute:

Since 2008, the number of passenger miles spent on express intercity buses, such as Megabus and Boltbus, has increased by about 2 billion miles. Additionally, the number of trips grew about 22 percent from 2010 to 2015.

During the same decade that we have seen expansive growth in express intercity bus services, Amtrak services have grown more slowly, only increasing passenger miles by less than 1 billion.

Intercity buses have been able to increase demand by adding features. Bus carriers, unlike Amtrak, have a greater ability to tailor their amenities to their clientele: free Wi-Fi and bus attendants for business-oriented routes, bottled water for trips to the beach, and family pricing for less expensive routes.

In addition, companies can test out new tech platforms, such as crowdsourced bus services, that can schedule routes and stops based on demand, offering more options and greater flexibility to travelers.
