Copenhagen has GREAT public transport. It is reliable, safe, and easily accessible. Of course, like everything in Copenhagen, it is not cheap. The system can be a little confusing, even for locals, but we’re here to help simplify it all for you! And today our focus is Travelling with a Bike.

BIKES ON THE TRAIN

Bicycles can be taken on s-tog lines for free but you can’t take bikes through Nørreport station during peak hours. To take your bike on a train, you need to put it on the first or last carriage, clearly marked with large signs of bicycles on the outside.

To take a bike on a regional train, which takes you to parts of Denmark outside Copenhagen, you must buy an extra ticket. The price depends on the distance and varies from 16 kr to 28 kr.

BIKES ON THE METRO

Bicycles can be taken on the metro for an extra 13 kr. You need to pay for the bike with its own ticket. You can’t take your bike on the metro during peak hours.

BIKES ON THE BUS

You can bring a bike on a bus but each bus is limited to two bikes, even if there is much space. Generally, people do not travel with their bikes on buses in Copenhagen.

BIKES ON THE FERRY(渡轮)

Charges for bicycles depend on the company and the destination. You will need to check with the ferry companies. When you book the ticket, you must state that you have a cycle, even if it’s free of charge.

The possibility of self-driving robot cars has often seemed like a futurist’s dream, years away from coming into reality in the real world. Well, the future is apparently now. The California Department of Motor Vehicles began giving permits in April for companies to test truly self-driving cars on public roads. The state also cleared the way for companies to sell or rent out self-driving cars, and for companies to operate driverless taxi services. California, it should be noted, isn't leading the way here. Companies have been testing their cars in cities across the country. It's hard to predict when driverless cars will be everywhere on our roads. But however long it takes, the technology may change our transportation systems and our cities, for better or for worse, depending on how the transformation is managed.

While much of the debate so far has been focused on the safety of driverless cars, policymakers should be talking more about how self-driving cars can help reduce traffic jams, cut emissions (排放) and offer more convenient and affordable choices to move around. The arrival of driverless cars is a chance to make sure that those cars are environmentally friendly and more shared.

Do we want to copy or even worsen the traffic of today with driverless cars? Imagine a future where most adults own their self-driving cars. They accept long, slow journeys to and from work on crowded highways because they can work, entertain themselves or sleep on the ride. They take their driverless car to a date and set the empty car to circle the building to avoid paying for parking. Instead of walking a few blocks to pick up a child or the dry cleaning, they send the self-driving minibus. The convenience even leads fewer people to take public transport — an unwelcome side effect researchers have already found in ride-hailing (网约车) services. Policymakers should start thinking now about how to make sure the appearance of driverless cars doesn't worsen the transportation system we have today. The coming technological development presents a chance for cities and states to develop transportation systems designed to move more people, and more affordably. The car of the future is coming. We just have to plan for it.
