Present Status and Progress
This project was taken up with a view to determine the impact of improvement / rehabilitation works on overloading, vehicle speeds, travel time and roughness for some State Highways (12 Corridors) in UP State.

The scope of work included the following:
Roughness measurements with 5th Wheel Bump Integrator for all the 12 corridors having a total length of 547 kilometer
Assessment of vehicle speeds through travel time and delays surveys, by using floating test car method in the traffic stream
Traffic volume and Axle loads surveys for all the 12 corridors using static weigh pads for 24 hours round the clock, on random sampling basis, covering all types of commercial vehicles
Determination of impact of improvement/rehabilitation works on overloading, vehicle speeds, travel time and roughness, for all the 12 corridors, utilizing the ‘Before’ data available prior to undertaking rehabilitation works
 
Findings/ Conclusions
All 12 corridors/links studied were double lane roads with pavement surface roughness varying from good to average value. Vehicle Damage Factors (VDFs) from axle loads survey were found to be varying from low to high for some of the corridors.
The Vehicle Operating Costs (VOCs) for different categories of vehicles were found out by using old and present roughness values (before and after upgradation) of the same corridors. The savings in VOCs accrued by various types of vehicles (in terms of Rupees per kilometer) were also determined which directly brought out the impact of improvement works.
 
Limitations
The study was limited to only State Highways Corridors. Similar study needs to be done for National Highways as well. This can provide a sound data base for (i) quantifying the benefits which can accrue due to the upgradation/improvement works and (ii) towards developing appropriate Pavement Maintenance Management System
 
Recommendations
The pavement performance data should be collected periodically particularly ‘Before’ and ‘After’ the upgradation works for conducting economic analysis etc.
