Public transportation:

Opening day of the light rail, December 27, 2008.
Valley Metro provides public transportation throughout the metropolitan area, with its trains, buses, and a ride-share program. 3.38% of workers commute by public transit. During the summer it is very difficult to wait for a bus in the heat as many of the stops have no canopies. Valley Metro's 20-mile (32 km) light rail project, called METRO, through north-central Phoenix, downtown, and eastward through Tempe and Mesa, opened December 27, 2008. Future rail segments of more than 30 miles (48 km) are planned to open by 2025.

[edit]Bicycle transportation
In 2000, bicycle transportation was a mode that 0.89% of Phoenix commuters utilized, down from 1.12% a decade earlier.
The Maricopa Association of Governments has a bicycle advisory committee working to improve conditions for bicycling on city streets and off-road paths.

The street system in Phoenix is laid out in a traditional grid system, with most roads oriented either north-south or east-west. The zero point is the intersection of Central Avenue and Washington Street. Numbered Avenues run north-south west of Central; numbered Streets run north-south east of Central. Major arterial streets are spaced one mile (1.6 km) apart. The one-mile (1.6 km) blocks are divided into approximately 1000 house numbers north and south, and 800 house numbers east and west, although this varies. Scottsdale Road, being 7200 East, is approximately 7200 / 800 = 9 miles (14 km) east of Central. The Valley Metro bus numbers are also based on this numbering system, with the Central Avenue bus being Route Zero, and Scottsdale Road being Route 72.
Phoenix is served by a growing network of freeways, many of which were initiated by a ½ cent general sales tax measure approved by voters in 1985. Before this network, Interstate 10 and Interstate 17 handled almost all freeway traffic in Phoenix, placing a large burden on surface arterial streets, leading to increased traffic congestion as the area grew in size.
The current freeway system comprises two interstate routes (I-10 and I-17), the nearly transcontinental US 60, and several state highways as well  including SR 51, SR 85, Loop 101, SR 143, and Loop 202.
Eventually, several other state highways (Loop 303, SR 801, and SR 802) will make their way into the system as they are needed.
