Which way do we go?
In 1985, 1985 the Malaysian Public Works Dept (PWD) produced their first Technical Instruction on Traffic Management at Work Zones ARAHAN TEKNIK (JALAN) 2C/85
12 ATJ 2C/85 (1985) - Focussing on Designs of TMP - Use of Standardised TCDs - Use of Templates for Placement of TCDs - In 2003, added Standard BQ
13 Use of Standardise TCDs
14 Use of Templates for Placement of TCDs
15
16 Use of Traffic Control Zones
17 In 2003, added Standard BQ 1985 2003 + ARAHAN TEKNIK (JALAN) 2C/85 NOTA TEKNIK (JALAN) 23/03
Standard Bill Of Quantities NOTA TEKNIK (JALAN) 26/08
In 2016, a revised Technical Instruction was produced
Then, A series of training, evaluations and audits were carried out....

✓ To carry out routine inspection on all traffic control devices. ✓ Frequency of inspection depends on several factors. ✓ Documentation can be done through Inspection Form. ✓ Record Keeping can be done through Inventory Forms together with Site Diary complete with photos and brief description (date, time, location, etc)
EXAMPLE FORM FOR IN INSPECTION
In addition… DESIGNS of TCPs have been simplified and standardised
STANDARD DEFINITIONS TMWZ – Traffic Management at Work Zone TMP – Traffic Management Plan TCP – Traffic Control Plan TCD – Traffic Control Devices TMO – Traffic Management Officer
SIMPLIFIED DESIGN APPROACH Traffic Categories
Traffic Categories vs Length of Areas
Construction Duration Categories
Construction Duration vs TCD (Temporary Lane Closure) Temporary Lane Closure) ( < 1 day )
Construction Duration vs TCD (Road Diversion) ( >1 day but < 1 month) ( > 1 month)
WORK ZONE LENGTH Work zone not including surcharge area • Length < 5km (rural) • Length < 2km (urban) Excavation • Length < 200m • Nos < 4
