"Public transport planning or transit planning is the spatial planning professional discipline responsible for developing public transport systems."
The study of designing and operating public transit systems such as buses, trains, subways, and light rail, to provide access to transportation options that are affordable, efficient, and convenient.
"It is a hybrid discipline involving aspects of transport engineering and traditional urban planning."
"Many transit planners find themselves involved in discourse with urban-land-use issues such as transit-oriented development."
"Transit planners are responsible for developing routes and networks of routes for urban transit systems."
"These may follow one or more models depending on the character of the communities they serve."
"In systems committed to this system, routes are designed to bring buses (or trains or ferries) together at a central location at predetermined times."
"To optimize the quality of trips for customers, some systems compensate by operating a timed-transfer system."
"In addition to serving customers' transportation needs, transit planners often consider transportation projects' other impacts."
"Economic impacts, directly on providers and consumers, on local economies, and on the aggregate level in large economic spheres, often feature prominently in deciding between different projects."
"In recent decades, concerns about environmental quality have produced a growing interest in developing sustainable transportation and transit planning has evolved to reflect these new concerns."
"Impacts on social equity have been paid increasing attention by transit planners in recent years."
