Impacts of Service Road on Level of Service of Urban Roads, Case Study- Delhi

Duration:January 2004 to June 2004
School of Planning and Architecture, New Delhi (R)

Scope and Objective
The aim of the research is to quantify the impact of service roads on the level of service of the urban roads.
(i) To appreciate the network and traffic characteristics of the service road in urban roads
(ii) To appreciate the road network evaluation techniques, evolve a suitable technique for application of study area.
(iii) To apply the selected technique of evaluation and prepare an improvement plan
(iv) To recommend planning, engineering, management and enforcement guidelines for the service roads

Methodology
Extensive study was carried out to review the studies related to assessment of level of service of the urban roads. IRC standards of LOS factors for urban roads were reviewed in terms of the V/C ratio and travel speed. Field studies and surveys were carried out for stretch without service roads and stretch with service roads. After doing the detailed quantitative and qualitative analysis of the present scenarios for both the stretches, capacity standards for urban roads with the selected categories of service roads were developed.

Findings and Conclusions
(i) Service road has no impact on utilization of inner lane, whereas utilization of middle and outer lane is affected by the      presence of service road Utilization of outer lane reduces and middle lane increases due to the presence of service road.
(ii) Over all V/C ratio of carriage way reduced due to the presence of service road. Service road has maximum effect on V/C      ratio of outer lane and minimum on the middle lane.
(iii) Over all journey speed on the carriage way improved due to the presence of service road. Service road has maximum      impact on the journey speed of outer lane and minimum on inner lane.
(iv) Journey speed on outer lane improve by 50.8%, whereas it improves by 12.6% and 6.3% on inner and middle lane       respectively for study area and overall speed of carriage way increase by 19.7%.
(v) Speed of public transport remains same in study area.
(vi) Due to number of openings along the service road in study area the traffic from the main road divert to the service road       which cause high traffic on service road in peak hrs.
