Buses are excellent local and regional public transportation options, but they will do little to spur redevelopment and economic investment in Downtown LA. This is due to the inherent flexibility of bus service, as routes change regularly to accommodate varying needs; in addition, buses contribute to nerve-racking pedestrian experiences due to heavy street-level emissions and noise pollution that discourages active use of sidewalks. Streetcars do the exact opposite. They provide developers and business owners certainty that the routes will not change, and are considered preferable to buses by residents, visitors, and employees as they offer more amenities, highly reliable routes and timetables, and enhanced urban experiences.
Buses and streetcars do, however, work together to connect access points within regional transportation networks. For example, sidewalks can be designed to specifically accommodate both vehicle configurations; in return, a transit stop effectively doubles its value within a regional transportation network.
