and South Midland units. The Oxford Bus Company was allocated the Oxford city services and the London routes, and South Midland was allocated the remainder of the network. Both companies were subject to management buyouts. The South Midland company was soon resold to Thames Transit (later Stagecoach South Midlands), which introduced minibus competition. Oxford Bus Company tried to counter this with minibuses under the Oxford City Nipper brand name. In 1990, the Oxford Bus Company acquired the High Wycombe operations of the Bee Line, and ran them under the Wycombe Bus brand name. In March 1994, the Go-Ahead Group bought Oxford Bus Company. In 2000, Go-Ahead sold the High Wycombe operation to Arriva. The company's long-established main depot in Cowley Road, Oxford was closed in 2004, replaced by a new depot opened in Watlington Road. In July 2009, Oxford Bus Company took over Oxford Brookes University's BrookesBus contract. Go-Ahead bought Thames Travel in 2011 and Carousel Buses in 2012. They now share Oxford Bus Company management but retain their separate identities. In October 2019, it was announced that the X90 service between Oxford and London would be withdrawn from 4 January 2020, due to a 35% fall in passenger numbers since 2015 causing the route to be unprofitable. Bus location technology All Oxford Bus Company buses and coaches have automatic vehicle location (AVL) equipment installed which works via GPS technology. The AVL equipment installed on each bus or coach gives geographical location to within a few metres and is updating central control room every few seconds. This information technology can therefore be seen in real time at the central control room, which helps in managing the fleet. The AVL equipment is also coupled to a real-time passenger information system at over 250 bus stop display screens around Oxford City and surrounding towns, and via a smartphone app. This coupled information technology system gives the public "predicted times" of bus and coach services around Oxford City and surrounding towns. Oxfordshire County Council also uses this information technology to provide traffic-light priority for buses at some road junctions. The real-time passenger information system is managed by OxonTime, which is a partnership between various bus companies and Oxfordshire County Council.
