But reductions in traffic will make living in currently congested areas more attractive and hence morepopulous.
但是，交通擁堵的緩解將使現(xiàn)有擁堵的區(qū)域更有吸引力，因此人口會更加密集。
Miles travelled per person might also rise, since self-driving technology frees passengers to use travel time for work or sleep.
每人駕駛的英里數(shù)可能也會增加，因為自主駕駛技術(shù)使乘客從開車的時間中解放出來，讓他們可以利用這段時間工作或睡覺。
And just as new highways prompt a rise in transport-intensive business, driverless vehicles could generate lots of new road-using activity.
同時，由于新的高速路促進了運輸密集行業(yè)的增加，無人駕駛汽車能夠產(chǎn)生更多新的公路活動。
Where now a worker might pop into the coffee shop before going to work, for example, a latte might soon be delivered in a driverless vehicle.
例如，現(xiàn)在的工人在上班之前可能會去咖啡店，可能不久以后一杯拿鐵就可以由一輛無人駕駛汽車中送到。
The technology of driverless cars may make us safer and more productive, but not necessarily lesstraffic-bound.
無人駕駛的技術(shù)可能是我們更安全也更有生產(chǎn)力，但是并不一定是更少的交通出行。
It might, however, improve traffic by making it easier, politically, to imposetolls on roads.
然而，可以通過在政治上更簡單征收公路通行費來改善交通情況。
Jams occur because a scarce resource, the road, is underpriced, so more people drive than it can accommodate.
因為公路這一稀缺資源定價太低，所以更多人開車，超過了它可以容納交通，擁堵就發(fā)生了。
But tolls could favour use of the roadway by those who value it most.
但是，通行費可能比較喜歡那些最認可公價值的人使用公路。
Some places already use such charges—London and Singapore areexamples—but they are rarely popular.
一些地方已經(jīng)開始使用這樣的收費——比如倫敦和新加坡——但是他們并不受歡迎。
Some drivers balkat paying for what they once got for nothing, and others are uneasy about the tracking of private vehicles that efficient pricing requires.
一些司機很不情愿地為他們之前可以免費使用的資源付錢，另一些人則對跟蹤私人汽車感到不安，而跟蹤是高效收費所要求的。
People seem not to object to paying by the mile when they are bring driven—by taxis and services like Uber and Lyft—and the driverless programmes now being tested by Waymo and GMfollow this model.
當人們乘坐出租車和使用像Uber和Lyft一樣的服務(wù)時，似乎并不反對按公里收費，現(xiàn)在有Maymo和GM測試的無人駕駛項目正在沿用這個模式.
If a driverless world is one in which people generally buy rides rather than cars, then not only might fewer unnecessary journeys be made, but also political resistance to road-pricing could ease, and congestion with it.
如果無人駕駛的世界是一個人們通常購買里程而不是汽車的世界，那么，不僅僅會有更少的不必要的出行，并且緩解了公路收費的政治抵制，同時緩解了擁堵。
