What is the identified problem?
Now a days traffic controlling in urban areas is becoming cumbersome. In present scenario irrespective of traffic congestion, traffic signal will be green for the time which was already programmed. If the vehicles are more in one way it doesn't give sufficient time to the vehicles to vacate the road.
Brief about Solution
• We are focusing on reduction of waiting time of a commuter.
•We will increase the duration of green light glowing time for
the way which consist traffic congestion and reduce if the traffic is less.
•To find the traffic congestion we are using IR sensors as
obstacle(vehicles) detectors
. •We will place two bunches(B11,B12)of IR
sensors at one side of the road at periodical
distances at particular height(at which vehicle disturbs the transmission of
IR). And respective IR receiver at other side of the road at same height. •We will place two bunches(B11,B12) per each road at adequate
distance from the juction. Each bunch will
consist 3 IR sensors(Circuit is designed in such a way that bunch value will be
True if most of the IR's have detected a True value) each bunch will be given a
sequence number.
•For a single bunch the value will be True if IR1,IR2,IR3
are(F,T,T),(T,F,T),(T,T,F),(T,T,T) and will be false if
(F,F,F),(F,F,T),(T,F,F),(F,T,F).
T=True
(if obstacle is present ).
F=False
(if obstacle is absent). •We will take bunch values (B11,B12,B21,B22,B31,B32,B41,B42)as
input to the Arduino board and time
delays for Green and Yellow signals(G1,Y1,G2,Y2,G3,Y3,G4,Y4) as outputs
•When the vehicle comes in the transmission way of IR sensors it
will give True value for bunch.By the
sequence number of bunch we will give the time duration for the Green light
using Arduino board(We will embed
the looping program on the arduino board).
Let us take a way from junction and give numbering as 1.
Respective bunches will be B11,B12. If (B11,B12) are (F,F) and (F,T) the green signal time
will be 40 seconds, If (T,F)-50 seconds, If (T,T)-80 seconds. •When 5 seconds are remaining in the G1 duration then the yellow
light of the next way(y2) will glow then it will be given for the duration
which will be decided by bunches(B21,B22) of way2.
•So the duration time of green light will be decided by the
distance covered by traffic.
How well does the proposed solution enable great commuter experience?
Since the more traffic is cleared at one time traffic jam would be less which in turn would increase the commuter travelling efficiency. Waiting time of commuters will be reduced. The idea will be very effective where small roads meet Highways with high traffic.
How attractive is this idea for partners from transportation, business, government, non profit or other sectors to get involved?
The idea is very attractive because it is cost efficient and require very less man power and effort. No new infrastructure is needed.
Environmental impact, whether the proposed idea in predominantly service based without adding more physical structures
No environmental impact because the radiation with IR sensors used is negligible compared to other radiating devices.
