3/26

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)


4/26

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)


5/26

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
