At the behest of the royal decree issued by the King, the security forces have modified the usual procedure of cutting off entire streets through which royals are passing and instead will partially reserve only certain lanes for the motorcades, Efe news quoted government spokesperson Narumon Pinyosinwat as saying in a statement.
"His Majesty the King was concerned that the motorcades might affect Thai people's commute. Therefore, his majesty has assigned the Royal Thai Police to set guidelines for citizens to transit regularly and to have the least impact," the statement said.
"The process of adjusting the protection pattern during the royal motorcades of the King and his royal family by the Royal Thai Police is intended to provide security to His Majesty the King and royal family at the highest standard to be dignified and in accordance with the wishes of His Majesty the King."
The new plans include opening lanes for the public to use at the same time as the royal motorcades, as well as allowing the use of U-turns and bridges.
These measures were introduced following an unusual wave of criticism on social media focused on the traffic chaos and disruptions generated by the royal family's land travels through Bangkok, one of the world's most congested cities.
The hashtag #RoyalMotorcade (in Thai) was a trending topic in October 2019, when many users complained about being stuck for hours waiting for the sovereign or his relatives to move through the capital's downtown area.
In December, a bridge leading out of the metropolis was shut down to allow the monarch to pick up his new yacht.
The outrage intensified at the end of the year, when many parts in southern Thailand, including the popular Phi Phi national park, were shut to the public because Princess Sirivannavari, the King's youngest daughter, was vacationing there.
In Thailand, any public criticism of the monarchy is extremely rare, since it has one of the harshest lese-majeste laws in the world that imposes penalties of up to 15 years in prison for offenders.
