The Pioneer Valley Transit Authority (PVTA) oversees and coordinates public transportation in the Pioneer Valley of Western Massachusetts. Currently the PVTA offers fixed-route bus service as well as paratransit service for the elderly and disabled. The PVTA was created by Chapter 161B of the Massachusetts General Laws in 1974. It is based in Springfield, Massachusetts, serves Hampden and Hampshire counties, and provides connecting service to the FRTA in Franklin County. It is the largest regional transit authority, and second largest public transit system in Massachusetts after the Massachusetts Bay Transit Authority, providing service to over 11 million riders annually across 24 municipalities in the region, with about 70% of all riders using the system as their primary mode of transit. Organizational structure As per Section 25, Chapter 161B of the Massachusetts General Laws, regional transit authorities in Massachusetts are not permitted to directly operate their service, but must instead contract with other entities to operate the buses. As such, the PVTA contracts with two entities to provide fixed-route service in the service area: First Transit and UMass Transit Services. The contractors run semi-autonomous garages that act as vehicle depots for the surrounding areas. Springfield Area Transit Company The Springfield Area Transit Company (SATCo) operates the southern portion of PVTA's service area, servicing Hampden County. SATCo, located at 665 Cottage Street in Springfield, is managed by First Transit. All SATCo fixed-route buses are numbered in the 1000 series. SATCo transports more than 9 million passengers annually. Fleet (Fixed Route Vehicles) UMass Transit Services UMass Transit Services operates PVTA's routes through the Five Colleges area in eastern Hampshire County and neighboring towns, with most of the routes centered around UMass Amherst, the largest ridership generator in the service area. UMass Transit Services is a department within the University of Massachusetts Amherst. The UMass Transit garage is located on-campus at 255 Governors Drive, Amherst. All UMass Transit fixed-route buses are numbered in the 3000 series. UMass Transit is a student-based organization with more than 90% of the employees (i.e. bus drivers, mechanics, dispatchers) being UMass students, with the remaining employees falling under University 03 employment status or full time administrators. UMass Transit Services is one of the oldest student driver groups in the country, having been founded in 1969 as a demonstration grant from the Urban Mass Transit Administration. UMass Transit Services operates 10 routes with a fleet of 40 transit vehicles (35'
