As the Covid-19 Movement Control Order (MCO) is in effect, we examine its influence on traffic. This map illustrates the traffic flow within the KL city centre before and during the MCO with dramatic results - an indication that the disruption may have brought unexpected benefits in reduced air pollution as witnessed in other locked-down cities.
Move glider to the left and right to see traffic before and during the MCO.
In this map, we examine the effect of the MCO on traffic, illustrating the contrast between traffic flow before and during the MCO.
The map shows 9 a.m. traffic before and during the MCO implementation. Before the MCO, there would be usually heavy traffic on almost every major road in KL city centre.
There is a massive difference during the MCO with very light traffic on major and minor roads.
In China and Italy, dramatic lockdowns have barred the movement of millions of people. There is a sharp drop in emimssions such as nitrogen dioxide, coming mainly from cars and factories.
When China started its lockdown in January and February 2020, a stark reduction was seen in southern cities around Wuhan, Hubei Province and Shanghai.
Similarly, when the lockdown started in Italy, fewer cars and reduced industrial activity led to a drop in nitrogen dioxide emissions in major cities in northern Italy, such as Venice and Milan.
