Route Groups

Route Groups oversee the daily operations of bus services under SBS Transit from various bus interchanges managed by the operator. Most bus services are assigned under Route Groups according to their originating points, with a minority of bus services from bus terminals grouped together with other bus services from nearby bus interchanges for ease of classification.

While bus deployments in SBS Transit are typically controlled by the depot, a Route Group complements the role of the Bus Operation Control Centre (BOCC) in the depot by ensuring that buses adhere to their schedules at their originating bus interchanges. In addition, a route group also complement the BOCC in handling contingencies in bus operations, such as accidents / breakdowns, as well as service delays that may disrupt the adherence of buses to their regular schedules.

Given their smaller areas of responsibility and fewer bus services, Route Groups are not typically applied for the operations of bus services under the other 3 operators (SMRT Buses, Tower Transit & Go-Ahead).

Classification of Bus Services in Route Groups

Bus services are typically classified under various Route Groups according to their originating bus interchange (with several exceptions). Bus services operating from bus stops or terminals do not have their own Route Group, but share a Route Group with a nearby bus interchange instead (E.g. Bus services from Sims Pl Ter fall under the Serangoon Route Group, which mainly manages bus services from Serangoon Int).

With the implementation of the Bus Contracting Model (BCM) in September 2016, bus services operated by SBS Transit under Negotiated Contracts (NCs) are generally assigned to their BCM route packages based on their allocated Route Groups in SBS Transit’s bus operations.

The table below provides an overview of how SBS Transit bus services are classified in their designated Route Groups:
