Abstract:

Capacity of roads plays a vital role in assuming better network characteristics and in providing good performance of roads. Capacity values play an important role for further modifications of roads. Various geometric measures like carriage way width, sidewalks, service roads, verge, medians, and road reserve and traffic patterns related to different roads. Passenger car equivalent (PCE) and Passenger car Unit (PCU) are typically used for road capacity analysis with heterogeneous traffic conditions. This paper presents important aspects of capacity evaluation for road designing using PCE instead of using PCU. Mathematical model is developed which uses IRC specifications on which regression analysis is performed for capacity values provided for urban roads, which are used for developing standard capacity functions. Relations between capacity and cross section elements are identified, which derives the capacity effecting zones. This relation helps in studying variation in capacity with respect to various widths of road elements. Traffic elements are also considered on par of analysing this measure with PCE property. Impact of geometrics and road elements on capacity is considered and capacity is derived on the basis of PCE and road geometric factors, which results in realistic prevailing road capacities, in Indian roads.
