Streetcars, bikes & whole ball of wax
Vancouver will have a trial short streetcar rail line that will run during the Olympics to handle large crowds. (from Olypmic Village Skytrain station to Granville Island). During Olympics, crowd capacity at Granville Island market area, is estimated at: 35,000 PER DAY. (Handy place to hang out for food and restaurant choices, art, shops, cultural events ..etc. away from any rainy days or even to enjoy outoors the views on beautiful days. Many tourists do come year-round.)
Vancouver stopped having streetcars after 1958. Now, it's looking very seriously at reintroducing streetcars in downtown..which means building streetcar rails in roads, etc. after Olympics. According to Bombardier, a major rail train manufacturer, several European cities have increased their streetcar fleet and lines in past decade to deal with high density population growth.
Coming from living in Toronto for 2 decades, from cyclist's standpoint, I find streetcars more of a hassle vs. buses or even trolley buses in sharing the road. However supporters do tout the greater capacity of streetcars to move more people in high density areas.
Would you want streetcars introduced/stay in your city? Of course, this is more applicable to bigger cities.
