Transport Indicator Database Survey was implemented first in Ghana in the year 2007. The second in the series was in the year 2012. This is a household based survey. The survey collects demographic, education, health, economic activity, acc
The efficient development, maintenance and administration of transport infrastructure and services are critical to the socio-economic development of any country. Scarce government resources and support from donor funds are required to provide these essential services to all sectors for the economic development of the country and for attaining equity and the participation of the populace in the creation of wealth and reduction of poverty.
To ascertain the effectiveness of implementation of policies and development programs, for transport related infrastructure and services key performance indicators are required. The data for developing these performance indicators must be collected on a sustainable basis by the various sectors for collation and analysis. Although most of the relevant basic data exist in many establishments, these are often scattered and are not collated nor disseminated in any structured manner. The Transportation sector is no exception. A recent study of the Ghana Road Sub-sector Programme finds that there is an urgent need to reinforce the monitoring system of MRT as performance indicators have only partially been collected and used; the road condition mix is monitored on an annual basis while other basic performance indicators are lacking. A good monitoring system will help improve the policy formulation within the sub-sector while its absence may result in a major fund funding reduction because the contribution to national development objectives, such as poverty alleviation, cannot be substantiated and demonstrated.
Objectives of survey
The development objective of the TSPS-II as defined in the Ghana Poverty Reduction Strategy (GPRS), to sustain economic growth through the provision of safe, reliable, efficient and affordable services for all transport users. The focus of the transport sector under the GPRS is to provide access through better distribution of the transport network with special emphasis on high poverty areas in order to reduce transport disparities between the urban and rural communities. The household survey is a component of a bigger programme which will serve as a reliable and sustainable one-stop shop for all the data and performance indicators for the transport sector. The immediate objective of the sub-component is to improve the effectiveness of implementation of policies and development programmes for the transport sector, including related infrastructure and services.
The direct aim of the sub-component will be the collection, processing, analysis, documentation and dissemination of transport related data, which will be useful for:
1. Transport planning and policy formulation;
2. Impact assessment, monitoring and evaluation of policies and programmes;
3. Measuring the contribution of the transport to the achievement of MDGs;
4. Impact assessment of the transport sector on poverty alleviation and the general standard of living;
5. Comparisons of performance of the transport sector over time and between countries for the purpose of drawing lessons and giving an indication of where interventions are necessary;
6. Provision of a comprehensive database for justification of programmes and projects under the Multi-Donor Budgetary Support (MDBS).

Household and Individual
Version 1.0 (September, 2014)
The Transport Indicator Database Survey (TIDS) 2012 is a household based survey.
The questionnaire is made up of various sections:
Section A: Household roster - Characteristics of individuals in the household with regards to their sex, age, relationship to household head etc
Section B: Education - Educational background of the individuals in the household
Section C: Health- Characteristics of the health status of individuals for four weeks preceeding survey
Section D: Economic Activity-characteristics are sought for individuals 7 years and older
Section E: Transport -Individual - For 6 years and older
Section F: Transport - Household
Section G: Access to market

The sample was representative of all households in Ghana. To achieve the study objectives, the sample size chosen was based on the type of variables under consideration, the required precision of the survey estimates and available resources.
Taking all of these into consideration, a sample size of 6,000 households was deemed sufficient to achieve the survey objectives. This was enough to yield reliable estimates of all the important survey variables as well as being manageable to control and minimize non-sampling errors.
Stratification and Sample Selection Procedures
The total list of the Enumeration Areas (EAs) from the demarcation for the 2010 Population and Housing Census formed the sampling frame for the Phase II of the Transport Indicators Survey.
The sampling frame was stratified into urban/rural residence and the 10 administrative regions of the country for the selection of the sample. The sample was selected in two stages.
The first stage selection involved the systematic selection of 400 EAs with probability proportional to size, the measure of size being the number of households in each EA.
The second stage selection involved the systematic selection of 15 households from each EA. See Appendix A for more details on the sample design.

Dates of Data Collection
Data Collection Mode
Interviewing was conducted by teams of interviewers. Each interviewing team comprised of 4 interviewers, a supervisor and a driver. Each team used a 4 wheel drive vehicle to travel from cluster to cluster (and where necessary within cluster).
Supervisors played an important role in ensuring the quality of data being collected. Among other things, the Supervisor:
(i) Review each questionnaire to be sure it is complete and internally consistent;
(ii) Helped to solve any problem in locating the listed households;
(iii) Helped the interviewers to understand the concepts in the questionnaire or interviewing difficult respondents.
The supervisor coordinated the field data collection activities, including management of the field teams, supplies and equipment, finances, maps and listings, coordinated with local authorities concerning the survey plan and made arrangements for accommodation and travel. Additionally, the field supervisor assigned work to the interviewers, spot checked the work interviewers did, maintained field control forms, and sent completed questionnaires and progress reports to the project secretariat at the head office.
Responsibilities of the supervisors were described in the Supervisors' manual together with the different field controls that were in place to control the quality of fieldwork.
Field visits were also made by a team of staff from the project secretariat on regular basis during the fieldwork.
Data Collection Notes
Training of enumerators and supervisors held for two weeks

The questionnaire had the following sections:
Section A: a household roster which collected basic information on all households members and household characteristics to determine eligible household members
Section B: an education section which was administered to household members aged 3 years and older on the use of transport services to school
Section C: a health section that was used to collect information on all household members on access and the use of transport services to health facilities
Section D: an economic activity section administered to household members 7 years and older to collect information on their economic activities and the use of transport services a market access section administered to household members engaged in agricultural activities to collect information on access to transport services for sale of farm produce
Section E: a general transport services section administered to all household members on the access and use of various modes of transport.
Section F: a general transport services section administered to all households and use of various modes of transport.
Control mechanisms were inbuilt in the data capturing application. Range checks and skip patterns were incorporated into the data capturing application.
Partial double entry was done in order to compare and correct errors. After data capture secondary editng was done in the form of consistency checks.
CSPro 4.1 was used to capture the data.
Softeware used to capture data was CSPro Ver4.1. The ascii data was then exported to SPSS.
Estimates of Sampling Error
Sample errors was calculated but not in the report.
