Bangalore: Intelligent signals reduce congestion
Intelligent signals reduce congestion
The traffic police plan to centralise control of signals, and launch the vehicle actuated signal system at around 25 junctions, shortly. Sai Prasanna reports
In a bid to make commuting across the city easier and traffic less congested, the Bangalore City Traffic Police will introduce a vehicle actuation system and centrally controlled signals. They are in operation in some junctions already and will be taken up on a larger scale now. Under BTRAC-2010, Rs 350 crores has been allocated for a period for five years to install signals, signage, CCTV cameras, and enforcement cameras. Every year, Rs 70 crores will be used for these improvements.
Signals
The city has 500 main junctions and 40,000 junctions totally, including crossroads. Presently, 256 signals have already come up in the city, and there will be another 150 signals by the end of this year. From January, all signal lights will be centrally controlled from the Traffic Management Centre (TMC). Senior officials in the traffic department say, "Depending on the volume of traffic, we will adjust the timings from the TMC to avoid congestion. No person should wait at a signal for more than 2.5 minutes. At some junctions like Central Silk Board junction, due to the heavy trafficvolume, we are already adjusting timings."
Once the signals are in place, CCTV cameras will be installed in phases. In each phase, 40 junctions will be taken up. The second phase is almost complete with 80 signals also having CCTV cameras. The third phase will begin next month. Each camera costs Rs 8-10 lakhs.
They are being installed to monitor the density of traffic and for security purposes. Officials say, "Every junction will have signal lights, after which they will be provided with CCTV cameras and then enforcement cameras." Presently, five enforcement cameras have been installed at Kamaraj Road-Cubbon Road junction, Hennur-Banaswadi junction, Padmanabhnagar junction, JP Nagar junction, and BHEL junction (near Tata auditorium). These cost Rs 45-50 lakhs each and there is a plan to have 10 more cameras by January. "We have not yet decided on the junctions where they should be installed. But Hudson Circle, Trinity Circle, Minsk Square, Basaveshwara Circle, and South End Circle are some of the junctions that will be top priority for installing them."
Also, five more interceptors will be bought now at a cost of Rs 25-30 lakhs. At present, there are two trafficinterceptors to bring negligent drivers to book.
Signage
The traffic police will come up with uniform signage on the Outer Ring Road (ORR) from Electronic City to the international airport. The signboards will come up at 80 points and will be located at a distance of one to two kilometres from each other. They will mostly come up at junctions and will have reflectors to enable people to see them even from a distance. The approximate cost to put up these signages is Rs 7-9 lakhs. Apart from this, 10,000 more signs like 'no parking', 'no entry', and direction boards at junctions have been ordered in the first instalment. As of now, 40 percent of these signs have already been installed.
Vehicle actuation system
From January, the vehicle actuation system will be in operation. Presently, every signal has fixed timings irrespective of traffic volume. This leads to unnecessary wait at signals even when there is no traffic. The vehicle actuation system will set timings for signals depending on the volume of traffic. Once all the traffic has moved, the signal will automatically change to let other vehicles pass, reducing the wait time. "During peak hours, the maximum wait for an entire cycle of traffic movement will be reduced to just one and a half minutes", the official explains.
There will also be different timings set for peak hours and lean hours. In the first phase, signals at 25-40 junctions will be made vehicle actuated.
Innovative RFID application for intelligent traffic signalling and positioning systems
Let me interest this forum about new RFID applications we are developing under the e-Safety and Intelligent Transport Systems (IST) domains.
It is based on embedding special RFID devices under the asphalt for alerting drivers about static and dinamic intelligent traffic signals on the road, improving sign awareness and reducing traffic accidents.
Also it works as a true competitive alternative for positioning systems not based on satellites.
We are currently looking for partnership from automobile, car part makers, and transportation industries.

Bangalore Cops Go For Keltron’s Intelligent Traffic System
Thiruvananthapuram:Posted: Monday, Jul 28, 2003 at 0000 hrs IST : Keltron’s (Kerala Electronic Development Corporation) latest breakthrough — Vehicle Actuated (VA) traffic assess system — has found its first patron. Bangalore Police has firmed up its Rs 1.2 crore order for the system.
As soon as the traffic assess system was developed, two units were tested in Karnataka. A string of 20 VA systems will now be positioned at high-traffic zones in Bangalore in the next three to four months, making it the first Indian city to have intelligent roads. Bharat Electronics Ltd is the implementing agency for the project. Unlike the electronically or manually operated system, the VA system assesses traffic density and facilitates smooth flow of traffic.
Keltron general manager (traffic systems) AV Ratnagiri told eFE that this was the first time that a VA system has been indigenously developed in the country. Sensor lights are embedded on the roads with the help of which the system assesses the traffic density. “For instance, the green light will automatically flash for a longer period if there are no vehicles on the road,” he explained.
The R&D division of the Kerala public sector unit had faced difficulty in locating clients with deep pockets to support the Rs 6-lakh per unit traffic management system. However, Bangalore Police armed with a Rs 6-crore traffic improvement budget for 2003-04, came to its rescue with the first contract.
The Kerala government, yet to find the resources to go for the VA system, is however trying out its cost-efficient version of LED (light emitting diodes) traffic signal system at two accident-prone spots in Chertala in central Kerala.
Two of Keltron’s solar traffic signal systems, one costing Rs 4.7 lakh and other priced at Rs 4 lakh for a four-armed junction and three armed junction respectively, are being tested here. With a one-time investment of Rs 4-5 lakh, these systems can work day and night for as long as 1 lakh hours. The only recurring investment is on battery repla-cement, usually once in two years, which works out to Rs 25,000.

The Beauty of Maps
Introduction
A stunning visual encyclopaedia fit for a King
This 16th century world map is drawn in the style of a sea chart, with 32 compass directions and navigational lines. But it is not what it seems.
The map is actually created as a work of art for the French King, Henri II (1519-1559), designed to be displayed in his ‘cabinet of curiosities’ or laid out on a table in his library.
The map comes from the renowned Dieppe School of Cartography. It is a large, hand-produced item by Pierre Desceliers, combining knowledge from both French and Portuguese sources – two pioneering nations in the Golden Age of Discovery.
One striking feature is how accurate the coastal lines are for a map of this period. Desceliers calls on geographical knowledge to paint a kind of visual encyclopaedia
This view of the world is based on a blend of classical sources and direct observation. It is a world-view from a time of nautical discovery, as well as being a beautiful Renaissance work of art.
The Desceliers’ World Map, 1550 is part of The British Library collection.
