iBus (London)

iBus is the name given to the automated vehicle monitoring and passenger information system used by Transport for London (TfL) on its London Buses network. The system tracks the real-time location of buses, enabling the display of estimated times of arrival (ETAs) at bus stops via electronic displays and online services.

iBus utilizes a combination of GPS (Global Positioning System) technology and radio communications to monitor the location and status of each bus. This data is transmitted to a central control center where it is processed and used to calculate ETAs. These ETAs are then disseminated to passengers through various channels.

Key components of the iBus system include:

• Vehicle Equipment: Each bus is equipped with an on-board unit that includes a GPS receiver, radio transmitter, and a driver interface. This unit transmits the bus's location and other relevant data to the control center.

• Control Center: The control center receives data from the buses, processes it, and generates ETAs. It also monitors the overall performance of the bus network and can identify potential disruptions.

• Passenger Information Displays: Electronic displays at bus stops show real-time ETAs for approaching buses.

• Online Services: The iBus data is also available to passengers through the TfL website and mobile apps, allowing them to plan their journeys and track the location of buses.

iBus has contributed to improved service reliability and passenger satisfaction by providing more accurate and up-to-date information about bus arrival times. It enables passengers to make informed decisions about their travel and helps to reduce waiting times at bus stops. The system also assists TfL in managing the bus network more efficiently and responding to disruptions in real time.
