It is well established that urban transport plays an important role in making cities livable and sustainable. Further, fast growth in urbanization and industrialization demands the use of more vehicles which leads to an imbalance between infrastructure availability and mobility demand. Historically, planners and decision-makers have proposed and practiced divergent approaches and policies for dealing with congestion. However, it is realized that traditionally it has been easier to advocate the novel approaches in the planning of new cities and also in cities that follow stricter regulations and are less dense. Nonetheless, it is experienced that much of the urbanization is happening in the existing cities, and in most of the developing countries the existing cities are characterized by narrow roads that are incapable of accommodating the growing traffic and have inadequate provision for parking, loading, and unloading facilities. This is further aggravated by the changing land use of the existing and mainly the old city areas. Eventually, this results in delays, deteriorating health of the city inhabitants, and fatalities due to road accidents. This harrowing experience severely undoes the benefits arising from the agglomeration effect of the urban economy. The situation is worse in metropolitan cities like Delhi, Mumbai, Lima, Bogota, and many capital cities across the developing world. In developing countries, multimodal traffic further worsens the situation. Many cities have implemented diverse strategies like introducing bus rapid transit systems, metro rail lines, constructing ring roads, and flyovers, but, still have failed to combat the growing menace of traffic congestion. New Delhi the capital city of India despite having one of the highest density of roads in the world and having a state-of-the-art metro transport network has failed to tackle daily congestion problems. With this background, the present paper attempts to identify the major issues and challenges on a typical arterial road that leads to congestion. The paper is based on a case study approach and attempts to identify and address the congestion issues on a 2.1 km stretch of Guru Ravidas Marg in New Delhi. There are multitudes of indicators and measurements available to analyze congestion levels. The authors adopted the common techniques of the traffic volume and level of service to establish the congestion level. Apart from this, the authors analyzed various other physical attributes like land use, street characteristics, and parking trends to comprehend the issues and challenges.
