Ride-sharing could reduce congestion, says US study

A new Massachusetts Institute of Technology (MIT) study suggests that using carpooling options from companies like Uber and Lyft could reduce the number of vehicles on the road by a factor of three without significantly impacting travel time.

A new 2024 Massachusetts Institute of Technology (MIT) study suggests that using carpooling options from companies like Uber and Lyft could reduce the number of vehicles on the road by a factor of three without significantly impacting travel time.

Led by Professor Daniela Rus, director of MIT’s Computer Science and Artificial Intelligence Laboratory (CSAIL), researchers developed an algorithm that found 3,000 four-passenger cars could serve 98 per cent of taxi demand in New York City, with an average wait-time of only 2.7 minutes.

The team also found that 95 per cent of demand would be covered by just 2,000 10-person vehicles, compared to the nearly 14,000 taxis that currently operate in New York City.

Using data from 3 million taxi rides, the new algorithm works in real-time to reroute cars based on incoming requests, and can also proactively send idle cars to areas with high demand, a step that speeds up service 20 percent, according to Rus.

“Instead of transporting people one at a time, drivers could transport two to four people at once, resulting in fewer trips, in less time, to make the same amount of money,” says Rus. “A system like this could allow drivers to work shorter shifts, while also creating less traffic, cleaner air, and shorter, less stressful commutes.”

    In its latest study, “Emerging Technologies: Autonomous cars—not if, but when,”, IHS Automotive forecasts total worldwide sales of self-driving cars (SDC) will grow from nearly 230 thousand in 2025 to 11.8 million in 2035 – seven million SDCs with both driver control and autonomous control and 4.8 million that have only autonomous control. In all, there should be nearly 54 million self-driving cars in use globally by 2035. The study anticipates that nearly all of the vehicles in use are likely to be self

    According to two university researchers, UK transport planning is not sufficiently taking into account the environmental impacts of transport choices. Their report, which is due to be presented at the Royal Geographical Society (with IBG) Annual International Conference today, says that road transport is the principal cause of air pollution in over 95 per cent of legally designated “Air Quality Management Areas” in the UK. Current estimates are that over 50,000 deaths a year can be attributed to air polluti

    Developing C/AV technology is the easy bit: now the vehicles need to gain people’s confidence. So does the public feel safe in driverless hands – and how much might they be willing to pay for the privilege? The Venturer consortium’s final user and technology test (Trial 3) explored levels of user trust in scenarios where a connected and autonomous vehicle (C/AV) is interacting with cyclists, pedestrians and other road users on a controlled road network. Trial 3 consisted of experimental runs in the

    Kapsch's Dietrich Leihs talks about the true fundamentals of urban pricing. In some Italian and German towns and cities, the solution to congestion is an outright ban on certain types of vehicles. As far as Dietrich Leihs is concerned, any attempt to sweeten the pill that is congestion charging is only ever going to be a partial success at best.
