Transit plays an important role in the development of our cities. Recent studies conducted by the Institute for Transportation and Development Policy have shown that efficient transit systems such as Bus Rapid Transit (BRT) and Light Rail Transit (LRT) spur urban development along their routes. However, the battle between BRT and LRT defenders is raging in cities like Hamilton and Winnipeg, where both camps have valid argument as to which solution is the most effective and financially viable. But what is the difference between a BRT and an LRT network?

As defined by the BRT Standard, an evaluation tool for BRT corridors around the world, Bus Rapid Transit differs from regular bus transit as it is operated in right-of-way corridors which are separated from other vehicular traffic in order to eliminate delays caused by congestion. Traffic signal priority is often implemented, giving buses a right of passage through intersections. BRT bus stops are usually less frequent than in non-BRT networks, and are characterized by an accessible passenger boarding station where patrons are required to purchase their ticket prior to embarking in order to speed up the boarding process.

LRT systems are less standardized, although they typically include single electric cars or short trains operating on a dedicated right-of-way. These may operate below ground, at grade, or on elevated tracks, while boarding and payment systems differ by city.

The implementation of an LRT system requires an important investment to lay the tracks — roadway refurbishment, power wires, and tunnel boring could all be involved in the process — as well as the construction of additional electrical and storage facilities, while operating a fleet of buses requires less specific infrastructure and a 50% lower initial investment. However, trains are proven to last an average of three times longer than buses, require less maintenance and are able to carry more passengers at once. With a similar return on investment but higher operating costs than BRTs, LRTs remain more popular in the eyes of passengers, easing the development of ridership.
