MANILA, March 28 (Xinhua) -- The Philippines has revived plans to remove jeepneys that are older than 10 years from Manila's gridlocked streets, stirring a fresh debate on the fate of the iconic vehicles that have been chugging along the streets since the 1950s.

The Philippine government and society have been talking about the "jeepney phaseout" for decades and the new "jeepney modernization" plan is an attempt to cut traffic emissions and ease the ever-worsening traffic congestion currently gripping the Philippine capital.

However, jeepney operators and drivers are up in arms over the planned measure, saying it is meant to kill off small transport operators in the country.

Last month, several transport groups took to the streets to protest the plan. Another group is mulling holding a similar demonstration in the coming days.

The jeepney, which traces its roots to the U.S. Willys jeep used by the U.S. army during World War ll, are elongated, flatbed passenger vehicles that have been plying the Philippine streets for more than five decades. It remains the main form of transport for millions of Filipinos across the archipelago.

Filipinos modified the Army Jeep, making it artsy by customizing the vehicle with Filipino touches such as chrome horses, banks of colored headlights, radio antennae, paintings of the Virgin Mary and unique artwork inspired by rustic scenes.

Indeed, the jeepney has become the symbol of Filipino creativity, ingenuity and innovativeness, making it one of the most recognizable icons of Filipino pop culture.

But critics say the jeepney has become a tarnished icon that has acquired a rather unsavory reputation, symbolizing the country's technological backwardness and inability to adapt to changing times.

The jeepney was often called the "King of the Road" because of their sheer numbers on the city streets or rural roads, but Jeepney drivers are notorious for never following traffic regulations.

The smoke-belching jeepneys that ply Manila's traffic-choked streets around the clock are blamed for clogging the roads, compounding the dismal traffic problem and dirtying the city's air.

Jeepneys are also being blamed for increasing road accidents, due in part to their wild drivers' notoriously reckless ways on Manila's streets. At night, jeepney drivers often don't use their headlights, making it dangerous for other motorists.

Ousted President Joseph Estrada, now the mayor of Manila City, made the jeepney his personal motif to symbolize his being "pro-poor" when he campaigned for president in 1998. He even named his showcase jeepney "Jeep ni Erap." Erap is Estrada's popular nickname.

The government wants to have the number of jeepneys pared down, if not phased out totally.

But the ubiquitous jeepneys have survived despite the rising popularity of the Japanese-made air conditioned Toyota Tamaraw FX, the Mitsubishi "mega taxis' on the streets and the elevated trains that run throughout the metropolis.

An estimated 220,000 to 230,000 jeepneys are on the streets of Metro Manila and other provinces on any given day, according to government statistics.

George San Mateo, the national president of a militant transport group, said the planned "jeepney phaseout" would affect at least 162,500 jeepney drivers and 45,000 operators.

Rather than making a business out of modernization, he said the government should extend support to drivers and operators to allow them to rehabilitate their aging units.

The Philippine Star, one of the leading English newspapers in the Philippines, ran an editorial recently saying the campaign of the Duterte administration to phase out jeepneys "will end up as another exercise in futility unless concerns are sufficiently addressed."

"One is livelihood for the drivers who will be displaced as well as the operators, most of whom are small-scale transport owners," the editorial said.

It said that so far the government has not come up with an alternative to the jeepney. "More buses must be fielded and the light rail and commuter train services substantially upgraded if the administration wants the jeepney phaseout to enjoy mass support," it said.

"Unless these concerns are addressed, the latest effort to phase out jeepneys will go the way of previous efforts -- straight to the wastebasket," the editorial said.
