3. INTRODUCTION
INTERSECTION
Allow the change
of route directions
of traffic flows.
Traffic control
systems are
capable to
reduce delays
and crashes on
intersection
Problem
of delay
still occurs
An area which
shared by two
or more roads.
4.
5. SIDRA
• Estimate of capacity and performance characteristics
• Analyze and optimize the intersections
• Determine signal timing
• Carry out a design life analyze for traffic growth
6. Advantages of using sidra
• Use the parameter sensitivity
• Use a lane-by-lane analysis method
• Consistent with the US Highway capacity manual
• Provide a Excel application to support model
comparison
• Estimate operation cost , fuel consumption , co2 &
other emission
7. Study objective
•The main objective of the Study is to prepare low cost
solutions to an existing intersection
8. Study area
The intersection is located in Nagavara junction
North side :Hebbal road
South side : KR Puram
West side :Shivajinagar road
East side :Thanisandra road
9. CASE STUDY OF NAGVARA JUNCTION BY SIDRA
INTERSECTION
The intersection is located in Nagavara junction
• Nagavara junction is a four phase signalized intersection
which has meeting junctions of a Hebbal road on north side,
thanisandra road in the east , shivajinagar road on the south
side and Kr puram road towards south . For the performance
evaluation of nagavara intersection like the Level of service,
Degree of saturation, delay , queue length, gap acceptance
etc using SIDRA INTERSECTION software
20. These data apply to
intersection as a whole.
Peak Flow Period : 15 minutes
Unit Time for Volumes: 60 minutes
21. Geometry Input dialog
The Geometry input dialog is used to configure approach and
exit lanes, modify movements and insert other characters
22. Geometry Input dialog (Lane & movements
tab)
we should click a
desirable leg to select it
To select a desirable lane, we
should just click the lane
23. we should click a
desirable leg to select it
We can allocate
desirable movements by
clicking these buttons to
the selected lane
24. we should click a
desirable leg to select it
To specify a Median for the
selected leg, we should click the
Median check box and then
insert the width of Median
25. we should click a
desirable leg to select it
In this boxes we can
input lane type, short
lane, and lane length
26. Volume Input dialog
We input the collected
volume data for the selected
direction according to
separate LV & HV method
28. Path data dialog
We insert MOVEMENT PATH
DATA for the selected directionFor example for our site,
approach cruise speed is 70km/h
Negotiation Speed, Negotiation Distance, and
Downstream Distance will be calculated by the
program
29. Movement Data input dialog
The defaults of
program for Movement
data are Accepted
30. Priorities input dialog
Priorities dialog establishes Opposing movements
for the selected movement
Select movement to be
defined as opposed
movement
Click desirable movements
to define them as
opposing/not opposing
movements
32. Phasing & Timing input dialog
In Phasing & Timing input dialog
We use command buttons to edit
We must click this box in
order to designate it as the
Current Sequence , Which
is analyzed by the program
37. Model Settings input dialog
The parameters of MODEL SETTING
affect the results significantly.
However, the defaults of parameters are
appropriate generally
49. CONCLUSION
• Performance evaluation of nagavara junction was performed
using sidra intersection -5 and the LOS of the intersection
was found to be F
• LOS-F means that there is high congestion in the junction and
there was low comfort and convenience to the commuters
travelling in this route
50. • So in order to increase the LOS and giving good traveling
experience to the road users we have to design the signal by
increasing the cycle time which can be done by
• Finding the optimum cycle length using websters method
• By user defined cycle time by trail and error method
• By user given phase time by trail and error method
comparing with the practical signal timing
