GENERAL INFORMATION
Cross Intersection in Four Legs:
Baghbazaar Dillibazaar
Singhdurbar Kamalpokhari
Two major legs and two minor legs
Signalized Intersection but currently the traffic
signals are not functioning. So, Traffic Police
Controlled Intersection (Manually Controlled)

GENERAL INFORMATION
Zebra Crossing for Pedestrians
Public Vehicle Stops very near to the intersection.
(These often interrupt the traffic flow from the
intersection during peak hours)

TRANSPORTATION UNITA Transport Unit (TU) is the impact that a mode of
transport has on traffic variables (such as headway,
speed, density) compared to a single car.
Amount of road space they occupy
The loads they impose on road structure
But in traffic engineering, we are mainly interested inthe equivalent congestion they create on the
roadway.

CONCLUSION AND RECOMMENDATIONS
Though the data is insufficient, it may be extended
for the use of signal timing design.
We can also find out the capacity of the intersection
and hence evaluate the adequacy of the intersection.
We can analyze this result to recommend better
measures for smooth vehicular flow
