Narrative Description of Project:

Japan International Cooperation Agency (JICA) intended to establish a data base for Persons Trip trends showing the movement patterns of people of Karachi. Ultimately, this data base was to be used for the development of traffic demand model of Karachi, which eventually would have to lead in the development of a detailed transport Master Plan for the city. The study covered the entire metropolis of Karachi City, which was further divided into towns and Union Councils. For collection of field data, a questionnaire was developed. The survey teams collected approximately 1 – 2% of the households of Karachi. The survey included information regarding socio-economic and trip indicators of the interviewees. A total of 26,300 households i.e. about 175,000 individuals were interviewed in the project. The samples were proportionately distributed to all the 18 tows, 178 Union Councils and 6 Cantonment Areas with respect to their population. The collected data resulted in useful information such as trip generation rates of various age groups, occupations, trip purposes. The study results were also used to determine correlations between socioeconomic characteristics of an individual with its trip making behaviors. Desire lines representing travel need distribution to and from all across Union Councils and Cantonment areas were developed. The study also resulted in a GIS based map representing travel patterns of city residents. The results of this study were field corroborated and then were used to develop a travel demand forecast model of the city as explained in Future Traffic Demand Forecasting Study for Karachi by JICA in 1008

Description of Actual Services Provided by Our Staff within the Assignment:

Conducting Household Interview Survey (27,300 households – about 150,000 individuals): The HIS is the key of such studies. These provide baseline information to build traffic models. These surveys include extraction of various facts related to socioeconomic conditions and travel habits, patterns & behaviors of city residents on weekdays and weekends. These surveys also help a great deal in developing desire lines and actual travel need between various traffic analysis zones. The most important aspect of these surveys is to first select the correct and representative sample size.
The project needed extensive data collection and processing, the major task involved in the project have been described as under:
  • Designing HIS Field Surveys forms
  • Developing HIS Training Manuals
  • Hiring field staff for conducting Surveys and QA
  • Field Staff Training
  • Supervision of entire data collection task.
  • Supervision Data Processing
  • Quality Assurance during all stages of Data Collection & Processing
  • Development of Trips Rate and other Mathematical Results
  • Preparation of Final Reports and Submission to the client
