Quantitative approach to determine pedestrian delay and level of service at signalized intersection

Abstract: Purpose: Level of Service is a widely adopted terminology to determine the efficiency of any transport system. From the literature it was studied that the multiple linear regression models established by many researchers to determine PLoS evolved with addition or removal of one or more physical parameters or with respect to the perception of users from different locations. At an intersection, there is little or no established methodology developed so far to determine a quantitative approach for PLoS similar to Vehicular Level of Service (VLoS). It was also pointed out that under heterogeneous traffic conditions, pedestrians are most vulnerable at intersections and they share the same space with motorized vehicles for crossing movements. Methodology: Thus, this study was built on the hypothesis that pedestrian delay of a signalized intersection is quantitatively dependent on pedestrian volume, vehicular volume and cycle time. Two signalized intersections operating as fully actuated and fixed cycle time were considered for study for period of four hours each, covering two hours of morning peak and off-peak hour traffic data. Main Findings: Using various statistical techniques, an empirical model was developed between the pedestrian delay and independent variables namely cycle time, pedestrian volume and vehicular volume. PLoS range was also determined through k-means clustering technique. Implications: The empirical model developed was validated and the application of this research was also explained. Novelty: The study is a new quantitative approach to determine PLoS and was limited to two intersections. Increase in the data may improve the accuracy of the model.

Using 3D GIS as a Decision Support Tool in Urban Planning

Abstract: Urbanization and especially suburbanization are increasing challenges to urban planner around the world. These processes occur at faster pace than regulatory bodies can manage and the use of geo-spatial techniques has become a must if we want to have any chance for a rational planning process. In this paper, a part of a broader question "can a 3D city model and its visualization support urban planners in obtaining a greater understanding of a given urban problem and enhance decision making?" is explored. A 3D information rich model (3DIRM) of case area (Kannadasan Nagar, Chennai) is generated using ArcGIS and ArcScene with the following information such as, land-use, road width, permissible floor space index (FSI), height of the building, setbacks, building use etc. Classification of 3DIRM based on local zoning regulation was carried out to check with the compliance of development codes. By strictly following code compliance, the buildings in case area can be classified into three types, ordinary buildings (OB-77%), special buildings (SB-20%) and multi-storied buildings (MSB-3%), whereas as the actual development observed is OB-75%, SB-4% and MSB-21%, more than 20,000 sq.m of built-up area is added under MSB typology which has gone unnoticed by the development authority. Results suggest that having an advanced geo-spatial tool such as 3D GIS can help urban planner in enhancing the decision making processes and the implementation of zoning regulations.

Urban rail system for freight distribution in a mega city: case study of Delhi, India

Abstract: The organization of urban freight distribution in developing countries is based on use of road vehicles which often results in high levels of traffic congestion, lack of parking space, lace of appropriate loading and unloading area which affects its efficiency. With the growing economy and increasing population Indian cities are focusing on their infrastructural development to mainly handle the passenger movement whereas freight sector is in complete negligence and further which contributes to the negative externalities like emission, safety, congestion and energy costs. Urban freight distribution through environmentally friendly modes is one of the advocated sustainable strategies worldwide which have immense potential to lower down the congestion and pollution levels owing to existing practices of freight distribution. This paper is an attempt to explore the potential of ring rail and metro rail system, presently used for passenger services, to be also considered for the distribution of freight, particularly postal and couriers in city of Delhi.
