Intelligent Transportation System (ITS)


    Introduction

ITS is an emerging transportation system which is comprised of an advanced information and telecommunications network for users, roads and vehicles. ITS is the integrated application of advanced Technologies using electronics, computers, communications, and advanced sensors. These applications provide travellers with important information while improving the safety and efficiency of the transportation system.




Intelligent Transportation Technologies

Wireless Communications:
Dedicated Short-Range Communications (DSRC): It offers communication between the vehicle and the roadside in specific locations (ex- toll plazas).
Continuous Air interface Long and Medium range: CALM provides continuous communications between a vehicle and the roadside using a variety of communication media, including cellular and infra-red links.

Intelligent Transportation Applications

(1) Electronic Toll Collection: Today, most toll roads are equipped with an electronic toll-collection system, like E-ZPass, that detects and processes tolls electronically. E-ZPass uses a vehicle-mounted transponder that is activated by an antenna on a toll lane. Your account information is stored in the transponder. The antenna identifies your transponder and reads your account information. The amount of the toll is deducted, and you're allowed through.

(2) Emergency vehicle notification systems: IST particularly the FCD (Floating Car Data ) model can also be used to provide advance warning to motorists of traffic jams, accidents and other emergency situations. This system can then provide alternative routes or recommendations to motorists so as to avoid congestion and travel delays.

(3) Automatic Road Enforcement: A traffic enforcement camera system, consisting of a camera and a vehicle monitoring device, is used to detect and identify vehicles disobeying a speed limit or some other road-legal requirement and automatically ticket offenders based on the license plate number. Traffic tickets are sent by mail.

Ex: Speed cameras identify a speed limit

Red-light cameras detect vehicles that cross a stop line

Bus lane cameras identify vehicles travelling in lanes reserved for buses.

(4)Collision Avoidance Systems :

     Collision Warning Obstacle Detection

 Lane Change Assistance Lane Departure Warning


Benefits of ITS :

Time Savings
Cost Avoidance
Reduced Crashes and Fatalities
Increased Customer Satisfaction
Energy and Environmental Benefits
Better emergency response times and services
Decreasing the probability of congestion occurrence

The Venice Tide Barrier System - MOSE Project

Image
Introduction: The city Venice located on the east coast of Italy, is a world-famous tourist spot. It was hit by several floods and massive waves from the Adriatic Sea in the past few decades. Many experts claim that the water level in the sea is rising day by day. In 1966, it became a significant concern as the tides rose to an enormous height of more than 7 feet above the seawater level. This project consists of 78 gigantic steel panels across the three inlets that allow water to surge from the Adriatic Sea into the Venice lagoon. The MOSE System: The Venice city lagoon has three main water inlets at Malamocco, Chioggia, and Lido. To protect the city from flooding, the government planned to temporarily close these three water inlets. In 2003, the approval for MOSE, an Italian acronym for Experimental Electromechanical Module, was passed to construct an artificial barrier that would protect the city from any future floods. Its fundamental idea was to engage a series of oscillating infl

Lasers: A Revolution in Highway Engineerin

Image
Introduction: - The advancement of new technology has been taking place since the beginning of human history. However, it has been exceptionally fast and changing the engineering world in recent decades at a record pace. One such technology, lasers, is used in highway engineering for various purposes like road profiling, pavement surface redirection, bridge deflection, speed checkers, accident spot analysis etc. These laser techniques have greater accuracy as everything is automated with faster data collection and less human involvement. Applications: - Road Profiling The profile of a path is calculated around some in-existent line or point which is permanent. Besides the rutting and the other issues, the profile of a path which is taken along a lateral line shows over the altitude and crown of the route outline. The longitudinal profile displays the ruggedness, hardness, and grade of the material. It is used for tracking the status of a pavement management system road network (PMS) ne

Alumni Talks with Ms. Priyanka Padhy

Image
Getting into a government job, and that too via something as prestigious as OPSC Examinations undoubtedly takes constant efforts and perseverance. But figuring out the right direction towards this acme can be a lot painstaking.  We talked to Ms. Priyanka Padhy, a 2018 Civil Engineering graduate of NIT Rourkela, who has achieved meritorious results in the OPSC Assistant Executive Engineer (AEE) 2019 by emerging as the Girls Topper and has secured the laudable Rank 10. As an alumna of the institute, we believe, she can be the best person to guide the students who carry this aspiration in their hearts.  Following is an excerpt. CEST CLUB (CC) : Walk us through your childhood days. Ms. Priyanka Padhy (PP) : I have completed my 10th as well as 12th standard from Saraswati Sishu Vidya Mandir, Neelakantha Nagar, Berhampur, Odisha. I believe school life is the most important phase of life where one learns basic principles of behavior and etiquette. My school life nurtured me to develop good ha
