Trends that influenced the current urban develop model (5)
Grid system, garden city, city beautiful, garden suburb, and neighbourhood unit.
Urban Development Trend: Grid System
“Make a City,” all streets run at right angel forming a grid. In Canada, the grid extends outward from the railroad. Ancient model. Example: Downtown Calgary.
Urban Development Trend: Garden City
“Leave the CIty,” to deal with the poor living conditions in the 1900’s - people were encourage to depopulate the cities in favour of satellite towns surrounded by green belt. Within there was a mix of agricultural, residential, and industrial. Example: Powell River, BC.
Urban Development Trend: City Beautiful
Fairly useless trend that attempted to solve poor living conditions in 1900’s by aesthetic means.
Urban Development Trend: Garden Suburb
Winding streets, large lots and parks, estate houses, and no business district. Created to house the professionals working in downtown locations. Example: Mount Pleasant.
Urban Development Trend: Neighbourhood Unit
Created to decrease traffic fatalities in communities while keeping communities connected to large roads. Suburbs, within large vehicle corridors, primarily residential, school within 500m walking, lots of cul de sacs, and minimals entrances and exits. Example: Tuscany.

Improve safety and livability by reducing vehicle speed, discouraging through traffic on local streets, minimize conflicts between street users, and enhancing neighbourhood environments.
Traffic Calming
Combination of mainly physical measures that reduce the negative effects of motor vehicle use, alter driver behaviour and improve conditions for non-motorized streets users.
How to reduce amount of energy used for private transportation? (5)
