  • Perhaps in the traffic jam, everyone thought, "Why didn't the government open the way to reduce traffic?" This makes perfect sense, the wider the road will have more space for vehicles, and then there will be no traffic jams. But unfortunately, things are not as simple as that. Let's find out the secret behind this paradox with VTL and how governments solve this problem!


    Over decades of transportation data in the United States, planners have realized that expanding and building roads won't improve congestion. For example, the plan to expand the Los Angeles I-405 in 2014, this project cost more than $ 1 billion and 5 years to complete. "But the data then shows that the current congestion rate on the I-405 is lower than before," says Matthew Turner, an economist at Brown University in the US

    Mr. Turner asserts that the cause of this phenomenon is actually quite simple - raising the road and paving the way will boost the mobility needs of the people, they will start traveling more and further than before, and that will make traffic jams more and more serious. Mr. Turner and Mr. Gilles Duranton, colleagues at the University of Pennsylvania call this the Paradox of transportation: Increasing the capacity of the road will simultaneously boost traffic density

    The paradox is almost applicable in every country because drivers do not have to pay to use the road. If you provide valuable resources for free, this will result in immediate higher demand.

    Only one option has been applied and successfully reduced the traffic congestion, which is tolls

    "Road tolls mean the government will charge a certain fee on transportation during rush hour." - Turner said. At peak hours, the use of all means of transportation from individual to public are priced higher than other times of the day. Currently, some big cities like London, Stockholm, Singapore and Milan have applied this model and obtained many positive results

    As in central London, many areas are marked as "Central Areas" - "Road tolls" with tracking security cameras will cost £ 11.5 per day per vehicle. in the area from 07:00 to 18:00, Monday to Friday.

    People who are aware of the cost of the road will cut their own travel needs, or move to travel at fewer peak times, greatly reducing traffic congestion

    However, the above model also received a lot of criticism for its drastic nature. Public opinion and a part of people disagree because this fee collection policy is extremely detrimental to the poor, who can not afford to pay for the road

    But road charges are also being applied by many countries and included in the price of gasoline, only that people often do not care much about it. Economist Turner said, “Road tolls will be a lot of hassle and may have an objection when first applied, but it will be the only option that will change people's behavior and lead to end the traffic jam.
