High Capacity Transit System Plan - <strong>Final</strong> <strong>Report</strong> June 2009<br />

Transit Technologies Analysis<br />

Impact on Land Development<br />

There have been some examples where BRT service with rail‐like attributes has attracted land<br />

development around certain stations. This has particularly been the case where separate busways<br />

or exclusive bus lanes on arterials have been developed. In Brisbane, Australia, and Ottawa,<br />

Cañada, millions <strong>of</strong> dollars <strong>of</strong> new investments in residential, <strong>of</strong>fice, and retail projects have<br />

occurred along their busway systems. In Boston, over $600 million in new development along the<br />

Washington Street corridor has been realized, much <strong>of</strong> it attracted by the new Silver Line BRT<br />

service that operates in exclusive bus lanes. Investments in facilities associated with BRT are<br />

almost always greater than investments in facilities associated with local and express bus service,<br />

and this greater investment conveys a sense <strong>of</strong> permanence that is more attractive to developers.<br />

4.2.3 Light Rail Transit (LRT)<br />

Basic Description <strong>of</strong> Operation<br />

LRT began as a development <strong>of</strong> the streetcar to allow higher speeds and increased capacity. LRT<br />

is characterized by its versatility <strong>of</strong> operation, as it can operate separated from other traffic below<br />

grade, at‐grade, or on an elevated structure, or it can operate together with motor vehicles on the<br />

surface. Service can be operated with single cars or multiple‐car trains. An example LRT train is<br />

shown in Figure 28.<br />

Electric traction power is obtained from an overhead wire, thus eliminating the restrictions<br />

imposed by having a live third rail at ground level. This flexibility helps to keep construction<br />

costs relatively low and explains the popularity this mode has experienced since 1978, when the<br />

first <strong>of</strong> 14 new North American LRT systems was opened in Edmonton. These newer LRT<br />

systems have adopted a much higher level <strong>of</strong> segregation from other traffic than earlier systems<br />

enjoyed.<br />

NOTE: Portland LRT operates with one- to two-car trains due to short downtown block lengths.<br />
