Transport in Dubai is controlled by the Roads and Transport authority. The public transport network faces huge congestion and reliability issues which a large investment programme is attempting to address, including over AED 70 billion of improvements planned for completion by 2020, when the population of the city is projected to exceed 3.5 million. In 2009, according to Dubai Municipality statistics, there were an estimated 1,021,880 cars in Dubai. In January 2010, the number of Dubai residents who use public transport stood at 6%. Although the government has invested heavily in the Dubai's road infrastructure, this has not kept pace with the increasing number of vehicles. This, coupled with the induced traffic phenomenon, has led to growing problems of congestion.

Road:
Five main routes - E 11 (Sheikh Zayed Road), E 311 (Emirates Road), E 44 (Dubai-Hatta Highway), E 77 (Dubai-Al Habab Road) and E 66 (Oud Metha Road) - run through Dubai, connecting the city to other towns and emirates. Additionally, several important intra-city routes, such as D 89 (Al Maktoum Road/Airport Road), D 85 (Baniyas Road), D 75 (Sheikh Rashid Road), D 73 (Al Dhiyafa Road), D 94 (Jumeirah Road) and D 92 (Al Khaleej/Al Wasl Road) connect the various localities in the city. The eastern and western sections of the city are connected by Al Maktoum Bridge, Al Garhoud Bridge, Al Shindagha Tunnel, Business Bay Crossing and Floating Bridge.
The Public Bus Transport system in Dubai is run by the Roads and Transport Authority (RTA). The bus system services 140 routes and transported over about 109.5 million people in 2008. By the end of 2010, there will be 2,100 buses in service across the city. The Transport authority has announced the construction of 500 air-conditioned (A/C) Passenger Bus Shelters, and has plan for 1,000 more across the emirates in a move to encourage the use of public buses.
Dubai also has an extensive taxi system, by far the most frequently used means of public transport within the Emirate. There are both government-operated and private cab companies. There are more than 3000 taxis operating within the emirate. Taxi cabs in Dubai make an average of 192,000 trips every day, lifting about 385,000 persons. In 2009 taxi trips exceeded 70 million trips serving around 140.45 million passengers.

Air:
Dubai International Airport (IATA: DXB), the hub for the Emirates Airline, serves the city of Dubai and other emirates in the country. The airport was the 15th busiest airport in the world by passenger traffic handling 40.9 million passengers in 2009. The airport was also the 6th busiest airport in the world by international passenger traffic. In addition to being an important passenger traffic hub, the airport is the 7th busiest cargo airport in world, handling 1.927 million tonnes of cargo in 2009, a 5.6% increase compared to 2008 and was also the 4th busiest International freight traffic airport in world. Emirates Airline is the national airline of Dubai. As of 2009, it operated internationally serving 101 destinations in 61 countries across six continents.
The development of Al Maktoum International Airport, was announced in 2004. The first phase of the airport, featuring one A380 capable runway, 64 remote stands, one cargo terminal with annual capacity for 250,000 tonnes of cargo and a passenger terminal building designed to accommodate five million passengers per year, has been opened. When completed, Dubai World Central-Al Maktoum International will be the largest airport in the world with five runways, four terminal buildings and capacity for 160 million passengers and 12 million tons of cargo.

Metro rail:
A $3.89 billion, Dubai Metro project is currently operational although partly under-construction. The Red Line is operational and runs through the heart of the city. The Metro system was partially opened on September 2009 and will be fully operational by 2014. UK-based international service company Serco Group is responsible for operating the metro. The metro comprises the Green Line from Al Rashidiya to the main city center and the Red Line from the airport to Jebel Ali. A Blue and a Purple Line have also been planned. The Dubai Metro (Green and Blue Lines) will have 70 km (43.5 mi) of track and 43 stations, 37 above ground and ten underground. The Dubai Metro is the first urban train network in the Arabian Peninsula.
The Palm Jumeirah Monorail is a monorail line on the Palm Jumeirah. The monorail connects the Palm Jumeirah to the mainland, with a planned further extension to the Red Line of the Dubai Metro. The line opened on 30 April 2009. Two trams systems are expected to be built in Dubai by 2011. The first is the Downtown Burj Khalifa Tram System and the second is the Al Sufouh Tram. The Downtown Burj Khalifa Tram System is a 4.6 km (2.86 mi) tram service that is planned to service the area around the Burj Khalifa, and the second tram will run 14.5 km (9 mi) along Al Sufouh Road from Dubai Marina to the Burj Al Arab and the Mall of the Emirates.
Dubai has announced it will complete a link of the UAE high speed rail system which will eventually hook up with the whole GCC and then possibly Europe. The High Speed Rail will serve passengers and cargo.

Waterways:
There are two major commercial ports in Dubai, Port Rashid and Port Jebel Ali. Port Jebel Ali is the world's largest man-made harbour, the biggest port in the Middle East, and the 7th-busiest port in the world. One of the more traditional methods of getting across Bur Dubai to Deira is through abras, small boats that ferry passengers across the Dubai Creek, between abra stations in Bastakiya and Baniyas Road. The Marine Transport Agency has also implemented the Dubai Water Bus System.
