investment with local councils and governments. The combination of participatory mapping integrated into the transport sector GIS allows for new forms of communication and the creation of a regular process of collaboration and decisionmaking within the sector. The methodology has also been a powerful tool of communication for MoPWT and local governments with other sectors, such as health and education. Rationalization studies in these sectors tend to emphasize spatial location, catchment areas, staffing, and kinds of services, but do not have efficient ways to investigate the role of access as an important barrier to the use of services. Having a methodology to analyze these issues across sectors and to highlight barriers is an important instrument for governments seeking to direct resources and maximize benefits for their populations.
