Left Turn Storage Lane| Urban and Infrastructure Engineering Department | Ned University of Engineering and Technology Karachi |

Problem

Congestion at NED University’s Main Gate during

peak hours

Hypothesis

• Add more lanes at the entrances after shifting existing banks

but it will cost money

• Provide a separate lane for Point but it will disturb the

equilibrium

• Restrict personal vehicles to avoid congestion but It is not a

permanent solution

Project Approach

1. Less Investment

2. Speedy solution

3. Provide better facility

4. Minimize travel time

5. Avoid accidents of pedestrians

6. Utilize available facilities to get maximum benefit

7. Safety and Security

Solution

Benefits

Left Turn Storage Lane:

It is the lane required to

store the number of

vehicles expected to

accumulate in the lane

during an average peak

period.

Results

Conclusion

• One report suggests that adding a left turn lane

increases approach capacity by approximately 25%

• The Federal Highway Administration has found crashes

can be expected to decrease 10% to 44% after

installing a left turn lane

• It is concluded that by providing the left turn storage

lane and by endowing the separate gate at the parking

area will solve problem regarding congestion and

security

Degradation

• It is costing us $0.7 billion a year to be stuck in traffic in

Karachi, roughly 2% of the city’s GDP.
