BEFORE – AFTER STUDY(AZIMPUR TO UTTARA)

DATA COLLECTION AND ANALYSIS

-Based on user response -Based on data collected in the bus stoppage

and on board

Observation and major findings

Conclusion & Suggestion

It is a common method to perform before after study to measure the promised performance.

It is mandatory to have a pilot project before implementing any major change in traffic system.

“Under the franchise system all existing bus companies will valid permit to operate on this route will run under one company”.

---- Abu Bakar Md. ShahjahanExecutive Director of the Projects Supervising Agency

Route Selection- No auction done

Priority – No separated bus lane

Ownership selection – No bidding took place

Promised Level of service(LOS) – Less LOS than ideal franchise

DISCUSSION(CONTD…)

Before introducing bus franchise system, there was no regularity in the discussed route . The passengers Had to wait for buses and some time more than one bus of same company appear at the same time on the same stoppage.

After installation of franchise system more responsibilities and seriousness among the drivers and contractors of the buses.

DISCUSSION(CONTD…)

But our another observation is that the congestion of the road has not been changed due to

mixed traffic,various side road entries,no advance traffic control system .

Therefore the coincidence of two or more buses

at the same location is still not rare .

DISCUSSION(CONTD…)

Better Comfort Of Passengers:

Due to better scheduling , the buses are now less crowded than before .As a result, the convenience and comfort of passengers has increased to some extent .

DISCUSSION(CONTD…)

Unchanged Travel Time : No significant change in travel time even after

the introduction of bus franchise system as the congestion in the main roads remain unchanged.

No bus priority on the road and the road is full of mixed traffic .

Before the franchise system, the buses travelled below Mohakhali Fly Over and now travel above the fly over . This change in travelling route has reduced the travel time a little

DISCUSSION(CONTD…)Insufficient Number Of Buses

and Ticket Changing Criteria On the route no 3/A, there is permission of

100 buses under “SUCHONA BRF ” bus company .

At bus counters it was found that there are only 15 to 18 AC buses operating on the route.

Due to small number of AC buses and irregularities in their arrival , the passengers were compelled to switch after arrival on non AC bus.

DISCUSSION(CONTD…)

This Ticket changing criterion has significantly effect on delay at bus stoppages .

CONCLUSION AND RECOMMENDATION Two major demand of passengers in an efficient

transport system are-

minimum travel time and minimum cost for travel .

Bus franchise in the route of Azimpur to Uttara provided comfort to passengers and brought convenience in their journey.

It failed to reduce their travel time significantly with reasonable travel cost.

So, we cannot recommend it as a successful one to fulfill the actual demand of

the passengers.
