RECOMMENDATIONS • Road Markings were found missing on major legs of the junction i.e. NH-44 part which
should be provided as per IRC-35.• No safe infrastructure for Pedestrians to Cross from one side to the other side of NH.
Pedestrian subway necessary due to a sport school just at the interaction.• Medians were not maintained properly and absence of Guardrails were seen, Hence
provision of the same to be confirm to IRC-119.• Appropriate signages are absent which should be placed as per IRC-67• Shoulders are not provided as per the requirement of IRC Manual IRC SP 87 and SP73.• Absence of refuge islands on all the four legs of the junction which should be provided as
per SP 87.• No barricading on the construction zone towards Panipat side of the intersection which is
hazardous, Hence it should be provided as per IRC-SP 55.• Presence of Boulders and New jersey barriers within the carriageway is hazardous and
should be confirm to IRC SP 55.• Defining Speed limits for approaching and leaving Traffic at the intersection for safe
mobility as per the IRC 67.• Appropriate lighting facilities to be provided at the intersection to increase the visibility
during odd hours and unfavourable driving conditions.

4. The Warning Signs for cut in median must be present at 180-245 m from the Hazard along with U Turn ahead informatory sin at appropriate distance
5. Speed Limit Signs must be placed at regular intervals
6. Provide Transverse Bar Marking (TM 08)
for psychological speed reduction
7. Provide Converging and Diverging Chevron Marking Sign as per Annexure A Table A.3 of IRC 35-2015

Other Desirable Recommendations1. Provide W-Beam Crash Barriers
along deep drainage ditches andalong the raised median (withrough surface)
2. The end of the W-beam Guardrail must be flared away Themodern approach is to providethe crash cushion or impactattenuators
3. IRC SP: 55 2014 for Work zoneTraffic Management Plan(WTMP) to be adopted forwidening/rehabilitation of theproject highway. All controldevices should be retro-reflective
4. Provide Road Studs as per IRCSpecifications Table 9.1(Warrants for Road Studs) of IRC84-2012 and IRC 35-2015
5. Provide A Truck Lay by forTrucks . Typical Diagram given inIRC-84-2012

Visibility
Invisible toll plaza in day time,
Absence of road studsHalf of canopy lights do not work
– so also invisible at night
No pole light just
ahead of toll plaza
Pole light
present
Toll booth lanes
Installation of retro reflective lights, road studs and lights as per IRC
recommendation
So road safety devices for rescue?
W-beam guardrails permanently
embedded in concrete Rigid barrier
Damaged barrier and traffic
cone in use
Design and use of guardrails, crash cushions, temporary barriers should be
improved

Additional road hazards!
Booby traps
Trucks parked on
either side of road
Vehicles parked for
repair adjacent to
median in front of
toll lane
Creation of separate zone for parking, repair works and removal of booby
traps is suggested
Car, Trucks,…Motorcycles, Pedestrians risk death.
May be not, if…
