Quick Response Technique For Travel Demand Estimation In Small & Medium Sized Cities In India

By Prof. Madhuri K. Rathi, Mr. Patil Vivek Prabhakar
Amrutvahini College of Engineering, Sangamner

To perform travel demand estimation for any city using conventional four step demand modeling, it would involve lot of time and resources. As of now, to understand the travel demand for a particular city using available parameters there are no ready reference models are available. Considering this, an attempt has been made in this paper to model the travel prediction using the readily available parameters. About six models were developed utilizing various parameters such as Population, Average Household Income, Road Network Length and area of the city. The models developed were validated by conducting the households’ surveys in two Cites Durgapur and Gwalior. Among the six models developed, the predicted values based on Population and City area are very close to the observed values of Durgapur and Gwalior cities.

Project Skybus

Miss Pallavi Dhamak

SkyBus is a greener way to travel. When delegates choose to travel on SkyBus between the Airport and the city they all leave a smaller carbon footprint. SkyBus supports Green fleet and plants over 7,000 trees each year to offset carbon emissions from its fleet’s fuel consumption. Sky Bus operates 24 hours/7 days a week- over 250 trips a day moving in excess of two million passengers.

Different types of Parking Spaces and Multiple Level Car Parking

Prof. Madhuri K. Rathi, Mr.Darshan V Patel
Department of Civil Engineering, Pune University, India

The growing population of India has created many problems one of the challenging ones being car parking which we confront almost every day. Besides the problem of space for cars moving on the road, greater is the problem of space for a parked vehicle considering that private vehicles remain parked for most of their time. While residential projects still escape with designated parking, the real problem lie with commercial spaces many a time which is overcome by taking extra open spaces to park.

Multi-level Parking systems for sometime have provided relief since they come with a number of advantages – optimal utilisation of space, lower maintenance and operational cost, lower construction cost, secure and environment-friendly nature, comfortable for the drivers, cost saving for builders by saving height or depth. Multiple Level Car Parking Systems are much in vogue a method of automatically parking and retrieving cars that typically use a system of pallets and lifts and signalling devices for retrieval. They serve advantages like safety, saving of space, time and fuel space but also need to have an extra and a very detailed assessment of the parking required, space availability and traffic flow.

In the Past, bitumen was used to waterproof roofs. The roof crack reflected through to the surface of each successive bitumen patch. The cracking problem solve if incorporated rubber in next round of patching. Roofing is a past or we also say that present waterproof barrier of environment & Human Effectiveness.

The primary reason for using bituminous rubber is that it provides significantly improved engineering properties over conventional grade bitumen.

What are the Types of Modifier in Bitumen?

By Nurul Hidayah

Bitumen is a black or dark brown non-crystalline solid or viscous material, composed principally of high molecular weight hydrocarbons, having adhesive properties, derived from petroleum either by natural or refinery processes and substantially soluble in carbon disulphide. Refer to Ali Akhber Yousefi (2002), bitumen in pure form is not suitable for modern roads and present traffic, therefore forced engineers to modify bitumen to improve its performance during service life.

The modified binder are more stable under heavy loads, braking and accelerating forces and shows increased resistance to permanent deformation in hot weather. It resists fatigue loads and having better adhesion between aggregates and binders.


There are 3 type of bitumen modifier, namely :
(1) physical modification
(2) chemical modification
(3) other type modification

The table 1 below showed the type of modifier and example of additive that being used to modify the bitumen.
