INTERCITY BUS ROUTES - HISTORY
EARLY CERTIFICATES OF CONVENIENCE AND NECESSITY
An interesting sampling, of the early evolution of interurban and intercity bus systems in select states. Information is not always easily available for the early bus companies, most of which were small privately held organizations. But some of these histories were documented in reports from various state regulatory commissions. For each bus route operated, a Certificate of Convenience and Necessity was required from the state regulatory commission. The availability and formats of this information varied among states, and usually was more complete for the earlier states to adopt regulation of motor carriers. Between 1914 and 1929, all states except Delaware began regulating motor transportation.
In searching online for reports from the various state regulatory commissions, or in general when searching for books which can be downloaded, often the year 1923 seems to be a benchmark year. Which perhaps relates to when certain materials typically become public domain. The reports from the state regulatory commissions usually are more readily available for before 1923. Meaning that less information is typically available for the states which adopted regulation later than the other states.
