In Bridge designing the live loads plays an important role. Most of the developed countrieshave their own code for highway bridges design specification while the other countries adopt certainrenowned design codes but with certain additions to meet their demands. In Pakistan, two different codesare followed for designing of bridges i-e American Association of State Highway and TransportationOfficials and West Pakistan Code of Practice for Highway Bridge. But both of these codes live loadmodels are not representative of the present truck traffic situation in Pakistan. For this research study,the MULLA MANSOOR weighing station was selected which is located on Grand Trunk road of Pakistan.This paper aim is to study the statistical analysis of weigh in motion data and comparative analysis ofshort to medium span length typical I girder bridges i-e 10m to 50m with 5m increment. This will help incomparing the live load effects with the actual truck traffic data for proposing a new live load model inPakistan. The method applied for achieving the objectives is based on Line load analysis i-e LoadResistance Factor Design Equations spreadsheet for bridges design in Pakistan for developing the Liveload model and modification in codes
