1-1 Background of the Project

Most of roads in Dar es Salaam were severely damaged and had deteriorated to a level that was not manageable by routine operation and maintenance (O&M). This problem coupled with the increasing number of vehicles in the metropolitan area led to constant traffic congestion within the city. The situation arose from an inadequate budget and the inappropriate application of O&M. To resolve this problem, the government of Tanzania established the Dar es Salaam Roads Improvement and Maintenance Project (DRIMP). Based on this, the Tanzanian government requested that the Japanese government conduct a study to develop a specific plan for the improvement and O&M of roads in Dar es Salaam. – In accordance with this request, the Japanese government provided assistance for the implementation of this study. With the study’s results, the government of Tanzania requested Grant Aid assistance to improve Dar es Salaam’s roads.

1-2 Project Overview

The project provided Grant Aid to provide the equipment necessary to improve two trunk roads and roads in three districts (expanding width, improvement of pavement, emergency repairs) and to perform the subsequent O&M in order to assist improvement of the Dar es Salaam roads.

(1) Overall Goal
To foster economic activities in surrounding regions and enhance access to social services through the improvement of trunk roads.

(2) Project Purpose
Traffic congestion on certain chosen routes is alleviated.-

(3) Outputs
1) Phase 1: Roads in the central district (regional roads) is improved, severely damaged areas are repaired and equipment necessary for road O&M is procured.
2) Phase 2: The Ubangi/New Bagamoyo Road (a trunk road) is improved.
3) Phase 3: The Morogoro Road (a trunk road) is improved.
4) Phase 4: Roads in the Chang’ombe and Kariakoo districts (regional roads) are improved.

4.102 billion yen 1991 : 896 million yen

1992 : 987 million yen

1993 : 1.333 billion yen

1994 : 89 million yen

1995 : 797 million yen

3. Results of Evaluation

3-1 Summary of Evaluation Results

(1) Impact
Regarding the effect of the road improvement, the results of a questionnaire for residents living along the roads concerned indicates that over 70% of the respondents stated that public transportation methods had made city transit more convenient. More than 60% responded that they were satisfied with the convenience of traveling by private car within the city. Very few respondents, however, felt that access to social services such as medical services had improved. Economic activity has intensified along trunk roads such as the New Bagamoyo Road connecting the suburbs, with a sharp increase in population along the road and a rise in the number of retail stores in the area.

(2) Sustainability
The volume of traffic is increasing in line with initial projections, but the speed of traffic fell below expectations as traffic congestion began to occur once again. This is due to the increase in the number of cars within the city and the rising population in the metropolitan area, in addition to the failure to reduce illegal parking on the roads.

The institute responsible for maintaining Tanzania’s domestic road network is the Tanzania National Road Agency (TANROAD), under the jurisdiction of the Ministry of Works. As for the district roads, however, local municipalities maintain their own districts after construction. Although the two municipalities in the targeted districts carry out O&M such as repairing minor damage to roads and cleaning the roads regularly, they lack the necessary staff to take care of major repairs. Also, the staff in charge of the construction and O&M equipment procured when the roads were built, do not maintain it adequately due to a lack of technical ability. TANROAD manages the traffic signals installed on the trunk roads, and these are maintained appropriately. However, many of the lights and signals along the local roads managed by the municipalities do not function. There are also cases in which they cannot be used due to irregular electricity supply.

Although there are problems with this O&M system, the roads seem to have been kept in good condition at the time of this study. There were not any situations calling for large-scale repairs or overhauls so far. The O&M budget is allocated by the Tanzania Road Fund Committee to TANROAD for the trunk roads and to municipalities for local roads. Since the budget is not divided into portions for each road, it is difficult to determine whether an O&M budget is adequate for the roads targeted in the project. Also, the Tanzania Road Fund Committee’s budget is used to develop new roads as well, so there remains a possibility that O&M funds for the completed roads will not receive as much priority as projects to develop and improve new roads.

3-3 Factors that Impeded the Realization of Effects

(1) Factors Concerning the Planning
N/A

(2) Factors Concerning the Implementation Process
Since the O&M budget is not adequate and also the O&M staff employed by the municipalities is not yet very technically skilled, the municipalities’ O&M is not sufficient.

3-4 Conclusion

This study confirmed that there have been considerable socioeconomic impacts. However, there are still budget and technical problems related to the sustainability of the O&M and—in particular—the management and updating of equipment used for O&M.

3-5 Recommendations

The O&M equipment needs to be managed properly. To ensure that this happens, the Tanzania Road Fund Committee should allocate the necessary budget to the relevant organizations. Also, strengthening technical aspects through Japan’s technical cooperation should be considered.
