Transcript

  • 1. “Road safety at road work sites”Mataram 30th and 31st January 2012Phillip JordanIndII Consultant
  • 2. Objectives of this presentation:1. To introduce you to road safety engineering.2. To introduce you to safer ways of managing your road work sites.3. To explain traffic management plans (TMP’s)
  • 3. The world has a large road safety problem.o 1.3 million deaths each year on roads of the worldo More than 15 million people injuredo Expected to increase rapidly, unless action is takenurgentlyo A “Decade of Action in Road Safety” has started
  • 4. Indonesia has a massive road safety problem32,000+ deaths each year on the roads of Indonesia (2010) Over 250,000 are injured (700 per day) - 2.5% of GDP 61% of deaths are motorcyclists 15% of deaths are pedestrians
  • 5. Road safety engineering is one profession that has an importantrole to play in road safety. Police, teachers, researchers, doctorsand others also have important roles in road safety.
  • 6. Manual 3 – Road Safety at Work SitesManual and accompanying DVD (Bahasa and English versions) A manual and audio visual aid that offers simple diagrams and information about how to sign and make various common types of road works (i.e., long- term on divided roads, short-term on busy undivided roads, work where a lane is closed, detours, etc)
  • 7. GLOBAL ROAD SAFETY – A CHALLENGE FOR US ALL A typical scene in many rapidly motorising nations
  • 8. Serious crashes at road work sitesare three times more commonthan on other sections of road.
  • 9. A fatal bus crash outside Palembang – in a road work site
  • 10. ARE YOUR ROAD WORKS UNSAFE? What do we look for? What more can we do? Do not blame drivers/riders for all crashes. Our roads are not perfect – we must improve them.
  • 11. What is unsafe with this side track?
  • 12. What is unsafe with this side track?
  • 13. What is unsafe here?
  • 14. Unsafe work practices No safety vests Few warning signs No protective barriersWhat is unsafe with this long term work site?
  • 15. WE SHOULD NEVER BLAME ONLY THEDRIVERS/RIDERS? There is more that we (engineers ) can do to contribute to road safety for all!!
  • 16. There should be no surprises on Indonesian roads!
  • 17. WHAT IS A ROAD CRASH?“a rare, random, multi-factorial event in which one or more road users has failed to cope with their environment.”
  • 18. AN UNNECESSARY TRAGEDY DUE TO ROAD WORKS! This man was one of five killed in a head-on crash with a truck in India. TheHighway was a divided highway (2 carriageways). The contractor had closed one carriageway for maintenance – sending all traffic two way along the othercarriageway. He did not inform the on-coming traffic to expect two way traffic – hence this tragedy. Remember this when you inspect the Airport Road later.
  • 19. These are crashes – they are not “accidents” We should use the word “CRASH”Accident implies that : the cause was unpredictable no human could have done anything to prevent it it is outside of our “control” It was in the “hands of the gods”
  • 20. We should use the word “CRASH”A road crash:• Can have “things” done to prevent it• Is within our “control”• Can be prevented• Is related closely to risk, and is predictable
  • 21. A road crash is the end result of a chain of events…To break that chain, where do we start??Lets look at a “typical” chain of events……
  • 22. The chain of events…… A 36 year old male is the driver of this truck. He is also the mechanic. His boss allows him to drive it home some weekends.
  • 23. The chain of events…… One weekend, he spends the whole (frustrating) weekend repairing it (especially the brakes which were worn) He finishes late Sunday – it took much more time than he had expected Friends drop around – just as he finishes the repair work Relaxing - they drink and talk until very late He does not get much sleep
  • 24. The chain of events……  Monday morning – he must start early loading sand at the river near the city.  Little sleep, no breakfast, late for work.  Drives the truck along a National Highway towards work.
  • 25. The chain of events……  Traffic is heavy.  The highway has unsealed shoulders.
  • 26. The chain of events…… He travels fast. Many motorcyclists – plus some pedestrians and bicyclists. Light rain is falling.
  • 27. The chain of events…… He drives very close to the truck ahead of him – impatient to overtake. He tries several times. The truck ahead has dirty/broken brake lights. There is a bus in front of that truck.
  • 28. The chain of events…… The road is very “slick” - it has little skid resistance. Wet. There are no sealed shoulders. Many big “drop-offs” from the pavement.
  • 29. The chain of events…… He knows there is an overtaking lane ahead – he accelerates to overtake the slow bus and truck.
  • 30. The chain of events…… Suddenly........roadworks! The slow lane is blocked; no advanced warning signs. The bus and the other truck swerve to the right - without warning.
  • 31. The chain of events…… Suddenly........roadworks! The slow lane is blocked; no advanced warning signs. The bus and the other truck swerve to the right - without warning.
  • 32. The chain of events…… Our 36 year old driver has no time to react – to avoid a “side swipe” collision he swings his truck to the right hoping to miss the other truck – hardly slowing. At that instant a motorcycle with 3 girls on it is travelling past in the other direction. They are not wearing helmets!
  • 33. The chain of events…… Our truck driver brakes late and hard – but the new brakes “grab”. The truck strikes the motorcyclists. It then side swipes the bus – tipping it over.
  • 34. One passenger dead
  • 35. • Two motorcyclists killed (head injuries), one very seriously injured. One bus passenger also dies.• Police and legal action follows What - in this chain of events - „caused‟ the crash ?
  • 36. Possible causes………• His frustrating weekend?• His drinking?• His lack of sleep?• Excessive speed?• His impatience and inattention?• The girls on the motorcycle – not wearing helmets?• The new brakes of his truck?• The dirty/broken brake lights of the other truck?• The rain?• The bus and truck swerving road because of the roadworks?• Materials being stored on the road?• The “slick” road conditions?• The lack of sealed shoulders?• The big “drop-off” from the pavement?• No advanced warning of the roadworks?
  • 37.  Engineers could have broken this chain of events by:  Sealing the shoulders (create an “escape” route)  Eliminating the big drop offs from pavements  Store materials off the road  Much better advanced warning of the road works Improving the roads – and especially roadworks sites – is one of the best things an engineer can do to improve road safety in Indonesia. YOU CAN SAVE LIVES!
  • 38. HOW CAN WE SAVE LIVES AT ROADWORKS?BY ENSURING – AT ALL OUR ROADWORKS – THAT WE:  Warn  Inform  Guide  Control  Forgive
  • 39. Road engineers should....o warno informo guideo controlo forgive Warning plus regulatory traffic signs
  • 40. Road engineers should.... o warn o inform o guide o control o forgive SPECIFIC INFORMATION
  • 41. Road engineers should....o warno informo guideo controlo forgive SPECIFIC INFORMATION
  • 42. Road engineers should.... o warn o inform o guide o control o forgive Plastic bollards, hazard markers
  • 43. Road engineers should....o warno informo guideo controlo forgive Traffic controllers
  • 44. Road engineers should.... o warn o inform o guide o control o forgive Speed limits
  • 45. Road engineers should.... o warn o inform o guide o control o forgive Temporary barriers
  • 46. Road engineers should.... Jelek!o warno informo guideo controlo forgive Very unsafe barriers
  • 47. Road engineers should.... Jelek!o warno informo guideo controlo forgive Very unsafe location
  • 48. Road engineers should....o warno informo guide Jelek!o controlo forgive Very unforgiving location
  • 49. Traffic control at road works is a major problem in most developing countries
  • 50. EVERYONE HAS A ROLE IN ROAD SAFETYAT WORK SITES Supervising engineers : Be aware of their responsibility to manage the site safely Appoint a Safety Engineer Provide safety training for all staff Monitor the site for safety Workers: Take responsibility for their own safety Follow all safety directions Wear safety vests at all times on the road Road users: Comply with all road rules, including speed limits
  • 51. 14At road works  Recurringunsafe practices observed in Indonesia at roadworks  Insufficient visibility to first advance warning signs  In the urban area, signs hidden by parked vehicles.  In rural areas, no advanced signs – or sometimes hidden by grass, trees  Use of illegal (unofficial) signs  Use of concrete blocks as delineators  Signs blown over  Little/no use of speed restriction signs  Lack of signing of side roads  Lack of flashing lights on construction plant
  • 52. 15At road works Recurring unsafe practices observed in Indonesia at roadworks  Lack of cones, and often no tapers.  Tapers too short.  Use of painted 44 gallon drums filled with concrete.  Excavations not separated enough from the traffic.  Little or no delineation of excavations.  No barrier protection for worker safety.  No barrier protection for pedestrians.  Workers not wearing high visibility clothing.
  • 53. NO TRAFFIC MANAGEMENT OR CONTROL
  • 54. TOO MANY SIGNS TOGETHER, CONFUSING
  • 55. NO SIGNS TO WARN OF SUDDEN CHANGE IN PAVEMENT
  • 56. UNSAFE “BARRIERS”, NO TRAFFIC MANAGEMENT OFONE LANE, TWO WAY TRAFFIC
  • 57. NO WARNING OF STOCKPILE AHEAD ON THISNATIONAL HIGHWAY
  • 58.  IndII and DGH has developed a manual to assist you, Contractors and Consultants to plan and implement safer road works sites. Please follow the manual to make your road works safer – for all.
  • 59. Manual 3 explains...........LONG TERM WORKS - LONGER THAN ONE DAYSHORT TERM WORKS - MOBILE - STATIONARYZONE CONCEPT - ADVANCE WARNING ZONE - TRANSITION ZONE - WORK ZONE - TERMINATION ZONEENCOURAGES YOU TO PLAN YOUR WORKSENCOURAGES YOU TO DEVELOP A TRAFFIC MANAGEMENT PLANGIVES YOU SOME DRAWINGS TO GUIDE YOU
  • 60. PART A – AN INTRODUCTION TOROAD WORK SAFETY
  • 61. Five phases of managing a work site
  • 62. FIRSTLY, YOUR ROAD WORKS NEEDS A TRAFFICMANAGEMENT PLAN What is a Traffic Management Plan (TMP)?
  • 63. TRAFFIC MANAGEMENT PLANS (TMP’S) A TMP is a plan that shows the signs, barriers and devices to be used at your work site for the duration of your work. A TMP should be prepared by an experienced and qualified engineer. It should then be checked for accuracy and safety. It is then implemented
  • 64. An example of a TMP
  • 65. Steps in preparing your Traffic Management Plan
  • 66. LONG TERM WORKS
  • 67. SHORT TERM (MOBILE) WORKS
  • 68. Steps in preparing your Traffic Management Plan
  • 69. PLANNING YOUR ROAD WORKS IS IMPORTANT Minimise the number of “starts” and “stops” along your road work. Have plenty of “good” signs available for use. Reflective. Clean. Correct. Make sure staff are trained and aware. It is their safety too! Safety vests for all.
  • 70. Steps in preparing your Traffic Management Plan
  • 71. Steps in preparing your Traffic Management Plan
  • 72. Through work area – most common.
  • 73. Past work area – also common.
  • 74. A side track ( by-pass) – less common.
  • 75. A detour – mainly in urban areas.
  • 76. Planning
  • 77. Safety vests are essential for all workers
  • 78. Think also of managing speeds and managing clearance distance between your workers and the vehicles

  • 90. PART C - TRAFFIC CONTROL DEVICESFOR USE AT ROAD WORK SITES
  • 91. MANUAL 3 PART C TRAFFIC CONTROL DEVICES FOR USE AT ROAD WORK SITES What these are? Signs Where they can be safely used? What design features to note? What these are? Speed restrictions What design features to note? What these are? Barriers Where they can be safely used - offsets, behind kerbing, deflections? What design features to note? Details of a variety of other devices Other devices such as lights, flags, flagmen, truck mounted attenuators, temporary signals.
  • 92. Signs – the most commondevice used at road works.
  • 93. Multi message signs areuseful for road works
  • 94. THREE COMMON PROBLEMS WITH SIGNSAT INDONESIAN ROAD WORKS No signs, or not enough signs Dirty, non-reflective signs (often incorrect ) Too many signs, wrongly placed too close together
  • 95. No signs entering road works
  • 96. No signs departing road works
  • 97. Not enough signs to alert drivers/riders
  • 98. Wrong sign – no workers here
  • 99. Wrong sign – no workers here after hours
  • 100. No signs to direct drivers/riders
  • 101. Placing signs
  • 102. SPEED MANAGEMENT Engineers must install correct signs Police must then enforce the new limit
  • 103. THINK ABOUT - AND ACT ON – ROADWORKS SPEED LIMITS
  • 104. Use a lower speed limit at your worksite if:- Workers will be closer than 3m to the traffic- Machinery will have to share the road with moving traffic- The H or V geometry will be effected by the road works sothat sight lines may be reduced.- There is loose material on the road.- Pedestrians and/or bicyclists may be present
  • 105. Remember line marking
  • 106. Two way traffic in a single traffic lane Give Way sign Temporary traffic signals Traffic controllers – each end with radios Do nothing – let traffic sort itself out!
  • 107. Do nothing – high risk, especially at night
  • 108. Five phases of managing a work site
  • 109. FOLLOW UP INSPECTION TO REPORTIMPROVEMENTS Approximately one month after this workshop, IndII consultants will again visit your EINRIP work site and will audit your signs/devices. IndII wants to see that our workshops are effective. We want you to help us but (most of all) help the road users.

  • 126. PART E – SETTING OUT DIAGRAMS
  • 127. For Indonesian roads Two lane, two way road Work site on the road, but still space for two lanes Provide advanced warning Manage the speeds Inform drivers of where to go Guide them there Manage them past the work site Tell them when they are out of the zone
  • 128. For Indonesian roads Two lane, two way road Work site on the road, but only space for one lane Provide advanced warning Manage the speeds Inform drivers of where to go Guide them there Manage them past the work site – give way signs or traffic controllers Tell them when they are out of the zone
  • 129. For Indonesian roads Two lane, one way road Work site on the road, but only space for one lane Provide advanced warning Manage the speeds Inform drivers of where to go Guide them into one lane – warning signs for lane drop Manage them past the work site – give strong tapers with plastic bollards Tell them when they are out of the zone
  • 130. For Indonesian roads Two lane, two way road Work site on the road, traffic drives through work site Provide advanced warning Manage the speeds Separate the two directions with delineators Tell them when they are out of the zone
  • 131. For Indonesian roads Two lane, two way road – being duplicated Work site closing one carriageway, all traffic to be detoured Provide advanced warning Manage the speeds Inform drivers of where to go Build an all weather detour track (fit for motorcycles too!) Guide them there Separate the two directions with strong delineation with bollards Tell them when they are out of the zone
  • 132. For Indonesian roads Two lane, two way road Work site closing one direction, all traffic to be detoured via one way side track Provide advanced warning Manage the speeds Inform drivers of where to go Build an all weather detour track (fit for motorcycles too!) Guide them there Provide strong delineation with bollards Tell them when they are out of the zone
  • 133. REMEMBER
  • 134. As the engineer responsible for a road work site,ensure that you act on the following key points:• Always prepare a traffic management plan.• Use the Zone Concept.• Make sure the zones are long enough to perform correctly.• For larger projects, have the TMP audited by an independentteam.• Work with local Traffic Police to keep speeds low through thework site.• Ensure the Contractor has sufficient signs/cones to fullycomply with your TMP.• Maintain a Safety (Buffer) Zone around the Work Area toprotect your workers.
  • 135. As the engineer responsible for a road work site,ensure that you act on the following key points:• Never allow concrete blocks/branches/rocks to be used fordelineation.• Inspect your work site every day – repair or replace anymissing or damaged sign or device.• Keep equipment and materials out of the clear zone.• Sweep the road regularly.• Put yourself into “the shoes of the road user” – what will theymake of your work?• Finally – record all/any crashes in your work site. Learn fromthese – can improvements be made.
