Roads play an important role in infrastructure and services in rural development. This is well established in the development
literature. There is a direct link which exists between productive investments and growth, social and economic infrastructure (such as
roads, electricity, water and sanitation, and communications) facilitates and integrates economic activities. The purpose of this study was
to assess the impact of road infrastructure in Yatta Sub County. Descriptive research design was used for the study. GIS and remote
sensing were used to capture images on road infrastructure while questionnaires were used to collect data from farmers and business
owners. Simple random sampling technique was used to sample respondents for the study. A total of 50 respondents were sampled for
the study where all responded giving 100% response rate. Descriptive statistics such as frequencies ad percentages were used to analyze
the quantitative data collected through questionnaires. Qualitative data collected through open ended questions were analyzed
thematically. Pre-processing of images involved: layer staking, radiometric correction, pan-sharpening, atmospheric correction and sub
setting while post-processing of images involved: Image classification, creating training sites, generating statistical tables, accurate
assessment and ground survey using GPS for ground truthing. The study found that roads which cover the Sub County are not
sufficient to serve the people of Yatta Sub County effectively. Most of the in-roads in this sub County are in very poor conditions
whereby people need to use motor cycle to reach their destinations. The findings revealed that most of the vehicles avoid using earth
surface roads as they spent more money on maintaining the vehicles. Where roads are in good conditions, growth of towns such as
Matuu, Kithimani and Katangi has greatly been realized. The poor road conditions led to high costs of living and doing business with
more time spent on movement from one place to another and difficulty in accessing social facilities. The study recommended that the
roads in Yatta Sub-County should be upgraded to facilitate movement of people and goods and that the County Government of
Machakos should embrace use of GIS in decision making and planning. |
