Identification and evaluation of traffic congestion are critical for better management of urban traffic, especially at merge sections where two different traffic streams converge and generate shockwaves. This study evaluates the travel time reliability measure (travel time index (TTI)) as a reliable congestion measure by analysing the impact of traffic flow parameters such as traffic volume, capacity

Network evaluation and prioritisation of rural roads using vulnerability analysis Proc. Inst. Civ. Eng. Transp. (IF 0.8) Pub Date : 2021-05-12 A. Modinpuroju, C. S. R. K. Prasad
The extent of a country's rural road network (RRN) is a major determinant of its economic activity and level of poverty. Connectivity to the rural population and the rest of the network are major tasks in the development of RRNs. This study envisages the consolidation of an existing RRN to improve its overall efficiency as a provider of transportation services for people, goods and services. Funding
