4. Project Background
Ashram
Intersection

5. Project Background
Direction towards (India Gate)

6. Project Background(Sailent Features)
1. Traffic at Ashram intersection is serving for
approx. 4 lakhs PCU/day
2. This Underpass is under construction at
the third level
3. Flyover is already constructed and
functioning at Asharam intersection
4. Length of the under pass is 300m
5. Two approach arms are Faridabad side &
India gate side having approach based
signal during construction
6. From the India gate side Nizamudin ROB
will merge near the Ashram Intersection.
7. Distance of mouth of Nizamudin ROB from
underpass is only 120m (safety Concern)

7. Importance of Construction stage RSA
oConstruction and maintenance work may pose various hazards for both
the site operatives and road users.
oProper signage and safety measures are required to warn and safeguard
the road users along with workers.
oIndian Road Congress; through its special publication IRC:SP:55 2014 has
standardised the safety measures to be adopted at work zones.
oAt all work places these standards for proper warning signage and safety
measures are to be adopted.
oTo ensure the adherence of these safety measures proper road safety
audit is required to avoid any accident or mis happening.

8. It is the safety plans with basic safety features and care needs to be taken so that
anyone coming along the road or the footpath from any direction understands exactly
what is happening and what is expected of him/her. The aim should be to facilitate the
passage of road users through such work zones using roadway geometries, roadside
features, and Traffic Control (TC) devices comparable to those for normal highway
operations. Thus, road user movement should be free from any hazard.
A WTMP should describe traffic control measures to be used for facilitating the safe
and efficient movement of road users through a work zone. WTMP should play a vital
role in providing reasonably safe and efficient road traffic flow for all road users when
a work zone temporarily disrupts normal traffic flow.
Principles and Planning of Work Zone Traffic Management
• Provide Safety for Road Users and Workers
• Minimize Hindrance or Delay to Road Users
• Provide Clear and Positive Guidance to Road Users
• Ensure Roadside Safety Maintenance
• Ensure that Planners and Decision Makers have the Necessary Knowledge
• Provide Good Public Relations
Important Consideration for Work Zone Traffic Management

12. OBSERVATIONS ON SITE BY SAFETY EXPERT

13. Observation: Traffic Management Plan is completely missing , Chevron & Hazard marking missing, Zebra
crossing is not up to complete carriageway not much provision for pedestrian. Buffer is not clear
(Entry, Exit and not proper tapering is done with delineators)
Reason of concern: Prior information of work zone missing, Risk
Priorty Highly desirable
Rcommendation: It should be as per IRC:SP:55-2014

14. Observation/Safety Concerns:
Approach Transition Zone Taper length (ATL) is negligible or too short. It may cause risk of accident due to lateral
shifting of moving vehicle from the normal pathway.
Risk: High
Recommendation:
As Per IRC 55:2014 Table 4.1 approach taper length shall be 1 (width of hazard including buffer ) :12 for speed
upto 50 km/Hr. at the start of traffic control zones.
Priority:
Highly desirable
Advance Warning Zone (Friends colony to Bhogal)

15. Observation/Safety Concerns:
New jersey barriers are missing. Road condition is very poor which is very hazardous for
road users.
Risk: High
Recommendation :
New jersey barriers shall be provided as against existing thin metal sheets. Existing road
shall be black topped
Priority :
Highly Desirable
Approach Transition Zone

16. Observation/Safety Concerns:
Proper road sign boards & New jersey barriers are missing.
Risk: Medium
Recommendation :
Proper road sign boards & New jersey barriers are proposed.
Priority:
Desirable
Work/Activity Zone
The activity zone is the section of the highway where the construction activity takes
place. It comprises the work space, the traffic space, and the buffer space

17. Observation/Safety Concerns:
GI Sheets as channelizing devices between work zone and traffic space without buffer zone.
Vehicles and pedestrians may fall in to excavation work area.
Risk : Very High
Recommendation :
Provide new jersey barrier with delineators and lighting devices with buffer space to protect
vehicles moving on traffic space.
Priority :
Essential
Work/Activity Zone

18. Observation/Safety Concerns:
There are no advance Warning Zone Signs observed.
Without Advance Warning Sign Board, vehicles may approach to Work Zone at high speed leads to crash.
Risk: - High
Recommendation :
As Per IRC 55:2014 Table 4.1 advance warning Sign should be installed before 180m of Work Zone for desired
speed of less than or equal to 50 km/Hr.
Placement of Man At Work, Speed Limit & reduction in the no. of lanes sign.
Priority :
Highly desirable
Advance Warning Zone

19. Observation/Safety Concerns:
There is no proper provision for pedestrian road crossing.
Risk: High
Recommendation :
There should be a well defined pedestrian crossing for pedestrian in connection with footpath
Priority :
Highly Desirable.
Work/Activity Zone

20. Observation/Safety Concerns:
There are no Terminal Transition Zone Signs observed due to which vehicles may approach to Work Zone at high
speed leading to crash. It may also cause casualties to pedestrians or other VRUs by traffic.
Risk: High
Recommendation :
The work zone end length shall extend from the end of terminal taper length to the last traffic control device such
as sign showing the end of road work.
Provide Work zone warning & Information Traffic signs
Priority :
Desirable
Terminal Transition Zone

21. Observation/Safety Concerns:
• Terminal Transition Zone Taper length (TTL) is to short. It may cause risk of accident
due to traffic from deviated path to their normal path
Risk: High
Recommendation:
As Per IRC 55:2014
Priority:
Highly desirable
Terminal Transition Zone

22. Observation:
Diversion signs are not proper
Reason of concern: Safety not
indicating proper direction for
smooth flow of traffic
Recommendation: It should be
as per IRC: 67 2012

23. Observation: Along the full rotary type movement two signals are provided for smooth flow of
traffic during peak hour. But chaos for NMTs
Reason of concern: But there are no markings for pedestrians, which is very risky as at the
other side metro station is also there
Recommendation: It should be as per IRC:35-2015 for pedestrians it should be recommended
as per IRC 103.

24. Observation:
This is left side entering to mathura road from ring road having three and a half lane road
including bus lane at present only one and a half lane is in use. Bus stand has been shifted.
Reason of concern: No arrow markings , no edge marking, no delineators
Recommendation: It should be as per IRC: 35-2015

25. Observation: Along the full Median side this type of FMM are placed not as per standard
spacing
Recommendation: It should be as per IRC:67-2012

26. Observation: Edge marking is
missing, barricading is of Tin type
Reason of concern: safety
Recommendation: It should be as
per IRC: 35-2015. Barricading to be
of type New Jersey

27. Observation: From Friend colony to Ashram intersection (Night time). construction zone Plan
is totally missing
Only Flexible median markers are provided
Reason of concern: Prior information of work zone
Recommendation: It should be as per IRC:SP:55-2001

28. Observation:
Faridabad to ashram intersection (Night
Time). Overhead gantry sign boards are
there but camoflauge it is visible from
10m only
Reason of concern:
Visiblity of sign boards
Recommendation:
Sign boards should be as per IRC
64(2012)

29. Observation: Delineation signs are totally missing in the construction zone or if placed not
proper
Reason of concern: Visibility issue, and hazardous risky
Recommendation: It should be as per IRC:35-

30. Observation:
Pavement surfacing is in bad condition
Reason of concern:
Riding quality is not good, which again
causes jam
Recommendation: Wearing coarse should
be put at construction zone pavement
surface should be maintained properly
with good roughness index

31. Observation:
No Retro reflective sheets , no sign
boards along the barricading as well as
on road
Reason of concern: visibility
Recommendation: It should be done as
per DS (4895)

32. Observation:
Edge marking is completely missing
on the carriageway
Reason of concern:
Risky, no demarcation of the
barricading
Recommendation: It should be done
as per IRC 55

33. Observation/Safety Concerns:
No sign of End Road Work is provided
Risk: High
Recommendation :
Proper sign should be provided on the
terminal transition zone.
Priority :
Essential
Terminal Transition Zone

34. Measures for Vulnerable Road Users (VRUs)
Observation/Safety Concerns:
• Discontinuous provision for Pedestrians, and no provision for differently abled
persons and people with visual impairment, for negotiate a work site or to cross
the roads within a work site.
• Existing footpath is discontinuous and absent of protected temporary footpaths
and formal pedestrian crossings
Risk : High
Recommendation :
Provision of continuous footpath (combination of existing and temporary footpaths (Min.
1 meter wide) with pedestrian barriers as per site condition
Priority :
Highly Desirable

35. Deployment of Personnel and Safety Compliance
• Work was on hold by pollution control board due to
higher Air Quality Index. Therefore Audit doesn't
cover any observations on workers, supervisors
and inspecting officers safety.
Good Industry Practices
• Deployment of flagman for controlling the traffic
during the peak and off-peak hours of traffic flow at
the construction zones.
• All the workers, exposed to moving roadway traffic
or equipment in road construction zones shall
wear high-visibility safety apparel, headgear,
boots, gloves and protective gears for their
protection.
• All workers and supervisors must adhere to safety
as per HSE norms and good industry practices.

36. • There are no advance Warning Zone Signs i.e. Man At Work, Speed Limit & reduction
in the no. of lanes sign.
• Approach Transition Zone Taper length (ATL) is to short in length.
• Improper channelizing devices between work zone and traffic space without buffer
zone at many locations
• Terminal Transition Zone Taper length (TTL) is to short. It may cause risk of accident
due to traffic from deviated path to their normal path
• The work zone end is without traffic control device such as sign showing the end of
road work
• Discontinuous provision for Pedestrians, and no provision for differently abled
persons and people with visual impairment, for negotiate a work site or to cross the
roads within a work site
• Existing footpath is discontinuous and absent of protected temporary footpaths and
formal pedestrian crossings
• Flagman's were also not observed for facilitation to pedestrians and vehicular traffic
at many hazardous locations.
• *Night time safety measures are not seen at site
