With the increasing number of vehicles on the roads, the management of traffic flow has become a major priority for highway concessionaires. This is especially so in the rush hours or during peak seasons when there is massive congestion on the roads. To deal with this problem, the MHA has imposed in the Concession Agreement that concessionaires must implement a Traffic Control and Surveillance System (TCSS), which are aimed at managing the highways efficiently and effectively.
In short, the TCSS major functions are as below:
- Traffic Information Collection – traffic congestion (loop); speed detector; emergency call (SOS) and CCTV (video)
- Traffic information processing – GIS; data fusion (alarm)
- Traffic information dissemination – Traffic Advisory (VMS); speed display
- Decision execution and enforcement – Incident management
Highway operators have undertaken various initiatives of their own to ease traffic congestion, especially during peak seasons and festival periods. For instance, during the Hari Raya celebrations in 2007, PLUS introduced a “Travel Time Advisory” service. Through its data research on the number of people travelling from Kuala Lumpur to Johor, Ipoh and other major destinations, the concessionaire grouped the travelers, provided a timetable and advised road users to plan their travel time accordingly. By providing up-to-date information to the public, the system has proved to be extremely effective. Currently, almost 60 per cent of PLUS highway users follow this schedule during the peak holiday periods of the year, thus reducing congestion significantly.
Lebuhraya Damansara – Puchong (LDP) has introduced a temporary Contra-flow scheme (KM19.3 – KM22) between peak hours of 4.30 pm to 8.30 pm from Petaling Jaya Selatan Toll Plaza (Sunway to Puchong). The scheme was introduced on 8 March 2010 primarily due to the many junction accesses where weaving in and out of the highway obstructs the southbound mainline traffic flow. The scheme offers the southbound traffic (Sunway-Puchong & Sunway Putrajaya) a dedicated lane to bypass the said heavy congested section. With the effectiveness of the temporary scheme, in 6 October 2012, LDP has introduced the segregation of toll plaza at the Petaling Jaya Toll Plaza to put in place a permanent scheme top replace the temporary contra flow scheme (Plaza A & B).
For the Eastern Dispersal Link Expressway (EDL), it was designed to effectively disperse traffic within and along the main artery roads including the Pandan Interchange, Bakar Batu Interchange, Jalan Tebrau, Permas Jaya/Pasir Gudang and Johor Bahru city towards the CIQ. Travelling at 90 kmh, motorists will take less than 10 minutes to complete the journey from the Pandan Interchange to the new CIQ, as compared to over 45 minutes of travelling time via Jalan Tebrau, which allows savings on fuel. Furthermore, motorists on EDL in Johor Bahru do not pay toll unless they cross the CIQ into Singapore.
Certain highway such as Kajang Dispersal Link Expressway (SILK) was designed to ease traffic congestion. For example, SILK, which encircles Kajang Town, is linked to major population centers in the south-eastern of the Klang Valley with other highway networks. Access to these highways – Federal Route 1, Lebuhraya Cheras – Kajang (GRAND SAGA), Lebuhraya Sungai Besi (BESRAYA), North – South Expressway (NSE), Lebuhraya Kajang – Seremban (LEKAS), South Klang Valley Expressway (SKVE) – is via grade-separated interchanges. These were built to ease traffic congestion, especially along Jalan Semenyih, Jalan Cheras and Jalan Sungai Chua. At the same time, it also provides an effective traffic dispersal system for Kajang.
Drivers who use Lebuhraya SMART (SMART) to travel to Jalan Tun Razak would save an average of 15 minutes during peak hours and 10 minutes during non-peak hours, compared to those who opted for Jalan Sungai Besi. Road users who travel via SMART to get to Jalan Sultan Ismail would also save an average of 15 minutes during peak hours and 10 minutes during non-peak hours compared to Jalan Sungai Besi.
Lebuhraya Kemuning – Shah Alam (LKSA) is distinctly known to be a main bypass to Kota Kemuning, Jalan Bukit Kemuning and Lebuhraya Shah Alam (KESAS) without using Persiaran Tengku Ampuan. Before LKSA, the only way to access Kota Kemuning is from Persiaran Tengku Ampuan, which was always congested, especially during peak hours. By using LKSA, travelling time to Kota Kemuning is cut from almost 30 minutes to 10 minutes.
Lebuhraya Koridor Guthrie (GCE) users will also save an average of 25 minutes from Rawang to Shah Alam during peak hours, where users will only have to travel for about 17 to 20 minutes as compared to 45 minutes before the highway was built.
ANIH Bhd introduced a “Travel Time Advisory” (TTA) service in 2009 during Hari Raya Aidilfitri for people who are traveling via Lebuhraya KL – Karak (KLK) and Lebuhraya Pantai Timur Fasa 1 (LPT1) to other major cities in the east coast region. ANIH’s TTA aims to help motorists to make a well informed travel decision by providing a timetable and advice on the traffic condition along its highway. ANIH now continues to provide the TTA during major festivities such as Hari Raya Aidilfitri and Chinese New Year Celebration.
