KIDEX Sdn Bhd chief operating officer Dr Shaharizuan Shafie said the company had commissioned a third traffic impact assessment (TIA), which will be submitted to the Malaysian Highway Authority (MHA) by the end of this month.
The report will incorporate new data from meetings and discussions with various authorities such as the MHA and the Petaling Jaya City Council (MBPJ).
“The first traffic study that was completed in 2012 was submitted to MHA in April 2012 and gave a rationale for the Kinrara-Damansara Expressway (Kidex).
“The second report was an update to the first study, incorporating data collected in the second half of 2013.
“It showed that 16 local roads would see a reduction in traffic of between 20% and 30% from 2018 upon Kidex being operational.
“The traffic reduction of 20% to 30% will increase to 25 local roads by the year 2028. They comprise routes such as Jalan Semangat, Jalan Selangor, Jalan Templer, Jalan Penchala and Jalan Kelang Lama,” he said in a statement.
Several Pakatan Rakyat assemblymen, however, have questioned this figure.
They said based on the report provided by Kidex to them, the average traffic flow on all the 43 affected roads would only be reduced by a maximum of 5.84%.
“The projections were done for 2018 and 2028. They show how traffic flow will be affected with and without the highway.
“In 2018, the traffic would only be reduced by an average of 5.84% with Kidex. In 2028, the average flow would only be reduced by 3.05%.
“This is nowhere near the estimations highlighted by Kidex,” said Damansara Utama assemblyman Yeo Bee Yin at a press conference.
The TIA was conducted by Rundingan Trafik MZK Sdn Bhd, a Malaysian company with over 24 years of experience in traffic and transportation planning.
The traffic modelling was conducted by Jacobs SKM — a global provider of technical, professional and construction services across multiple markets.
Yeo said some 43 roads, both in Petaling Jaya and Puchong, would be affected by Kidex.
“The figures given in Kidex’s preliminary TIA are not convincing,” she said.
She said in 2018, upon the completion of Kidex, roads such as Jalan Barat would see an increase in traffic flow by 35%, Jalan Sultan by 58%, Jalan Changgai by 109% and Jalan Bukit Jalil Indah by 233%.
It is estimated that in 2028, the projected figures would be almost the same as the ones in 2018, said Yeo.
Bukit Gasing assemblyman Rajiv Rishyakaran questioned why the report was not comprehensive.
“A small development in Petaling Jaya will have a thicker TIA compared to the one we received from Kidex. The report given to us is a pretty presentation.
“We want the numbers and facts, not presentation slides,” he said.
He cited the one-way-loop plan in the Petaling Jaya city centre.
“The residents were first against the plan. However, they agreed to a trial run when MBPJ revealed the actual plan. The same may happen with Kidex if the public is provided with a more detailed study,” he said.
Kinrara assemblyman Ng Sze Han and Kampung Tunku assemblyman Lau Weng San, who were also present, urged that more information be provided.
