Traffic and Transportation

Traffic and Transportation Division conducts research and provides advisory services in road traffic management, transport planning, road systems design, construction and maintenance, and all aspects of road safety management.


SECTIONS WITHIN THE DIVISION
For effective and efficient delivery of research and consultancy services to the public, the Division has been subdivided into three sections, namely:
-Road Safety Research Section;
-Road Traffic and Transport Section, and
-Highway Engineering Research Section



AREAS OF COMPETENCE
1. Road and traffic studies for cost-effective planning, construction and maintenance of Highways, Urban Roads and Feeder Roads covering:
- Vehicle classification Counts and Spot speed studies
- Network Capacity Analysis
- Axle Load Surveys
- Road Roughness Surveys
- Passenger and Freight (goods) Transport Surveys
- Vehicle Operating Costs

2. Geometric and Pavement Design of Roads
3. Urban Traffic Management including Parking, Traffic Signalisation, Congestion indices, Road Signing, Channellisation, etc.
4. Urban Transport studies including Bus Journey Times and Loadings, Transport Demand, Terminal Performance, Travel Time indices, etc.
5. Road Construction Supervision and Management.
6. Road Safety Management including accident data collection, coding, analysis and identification of accident hazardous (blackspots) locations and design of remedial measures.
7. Safety-Auditing of Road Designs.
8. Testing of Road Safety related products.
9. Training of Highway and Traffic Engineers and the Police in Road Safety Applications and Management.
10. Monitoring and Evaluation of Road Safety Enhancement schemes.

SOME MAJOR ACHIEVEMENTS AND CONTRIBUTIONS TO THE ECONOMY
1. Development of National Road Traffic Accident Database for Road Safety Management, Policy formulation and Research. A database has been developed at the CSIR-BRRI, Kumasi, from which annual accident statistics are produced to establish the trends, patterns and to identify the key traffic safety problems, regional safety characteristics, critical accident contributory factors and low-cost remedial application measures to improve road traffic safety in Ghana. Preparations of the national road safety strategic plan and national road safety education plan have also been largely informed by the available accident data.

2. National Accident Management Project (NAMP). This project was carried out
for the then Ministry of Transportation under the Road Sector Development Program (RSDP) to improve the existing accident data management system and to train staff of the National Road Safety Commission, the Road Agencies and allied traffic safety practitioners in accident software applications and best road safety management practices.

3. Estimation of National Annual Accident Costs. The annual cost of road traffic accidents to the nation was estimated to be 1.6% of GDP using 2004 constant prices and the Gross Output Approach. This involved medical costs, administrative costs, loss of output, and property damage costs. It was established that fatal crashes alone accounted for more than 60% of the cost of road traffic crashes and that efforts must be geared towards the minimization of fatal crashes in Ghana.

4. Evaluation of accident black spots improvement measures on some selected major highways. The studies involved the collection and analysis of road traffic accidents using the before and after situations for comparison with control sites, in order to assess the effectiveness of the remedial measures using statistical tests. Vehicle speeds, pedestrian behaviour and other traffic safety attributes were measured. The speed tables were found to significantly reduce speeds and road traffic crashes compared to the other safety measures.

5. Accident black spots identification on the major highways and urban road networks. Accident black spots were identified on the highway and urban road networks. On the highway network, some 100 worst sites were identified and in-depth analysis carried out to establish the causes and possible remedial measures likely to improve the safety of the locations. The urban road networks involved the arterial roads in the 5 major cities, namely Accra, Kumasi, Sekondi-Takoradi, Tema and Tamale. The spots identified and the recommendations made formed the core implementation framework for the improvement of road safety on the road networks by the Road Agencies.
Documented over 50 technical and projects final reports.
