Introduction
All the metropolitan cities of India are counting today on widening of roads and building
flyovers to smooth out the ever increasing traffic. Congestion has been one of the vital problem
of all of the big cities' road transport. There have been many new technologies developed to
ensure smooth traffic flow by regulating the delay time at traffic signals. If the traffic signals
start operating according to flow and type of vehicles, incorporating new technologies, smoothand safe transportation may be ensured.
The competition provides you the opportunity to design a city road transport network and
place the signals at different intersections, operating according to need of hour to ensure a
comfortable Drive through the City.
Problem Statement
Given a city’s small road network withvehicles’ number and composition, design the signalized city road
transport network and simulate it on the student version of the VISSIM software. (You can download
the software Here and in case you find it hard to download you may request us to send the CD of the
software at [email protected])
Prizes worth INR 25,000 to be won.

Network Specifications
1. The figure 1shows a city road network with 12 signalized intersections.
2. There are four entry and exit points named as A, B, C and D
3. Below is the no of vehicles, tabulated in a 5 x 5 matrix, that are supposed to enter and exit through all
such points
Table 1
A B C D
A - - 1500±2% 1500±2%
B - - 1500±2% 1500±2%
C 1500±2% 1500±2% - -
D 1500±2% 1500±2% - -

4. The entry in 2nd row and 4th column of the matrix implies that vehicles starting from point A and
exiting at point C must be less than or equal to 1500±2%.
5. Blank entry in 2nd
row and 3rd
column implies that no vehicle entering from point A will exit at point B.
6. Every road link must have less than or equal to six (3 on either side) lanes.
7. The lengths between the two intersections in the images are given in figure, 1m ≡ 100m. There may
be an error of L±5% in the lengths of the links. But the total length in the horizontal and vertical
direction must not exceed 1000m.
File Submission
1. Participants are required to submit the VISSIM input file with the Document File named Doc_City
Drive in the qualification round for the competition on or before 25th November. This will be the basis
for short-listing of teams. Only short-listing teams will be eligible to participate in the final round of city
drive at Techfest 2011.
2. Top few winning entries will be called here in Techfest 2011 from 7th-9th January, 2011 for the final
round of competition with a modified problem statement using student version of the VISSIM software.
3. The VISSIM input file and the Document File named Doc_City Drive must bemailedatcitydrive[at]techfest[dot]org with subject "ArchiTech: City Drive Files Reg. No. xxxx " (For ex.
ArchiTech: City Drive Files 1243).
4. All the details required are explicitly specified in the Document file. Fill in the required detailscorrectly
and exactly the same as used in the simulation in VISSIM input file.
Three details that must be present in the solution are:
a) Cycle length: Cycle length in sec is the total time for which vehicles remain halted at a particular
intersection.
b) Green time: Green time is the time interval between the two green signals at a particular
intersection.
c) Phase plan: The sample plan for different lanes is described pictorially in the Doc_City Drive

Rules and Regulations
Rules related to software uses
1. Participants must use the student version of VISSIM software to present their traffic plan. You
can download the software here and in case you find it hard to download you may request us to
send the CD of the software at [email protected])
Please go through all the details regarding the compatibility and the uses of the software in the
tab Software Details.
2. The participants must use maximum three lanes for all the road links. In the simulation
participants must make use of every road-link provided in the network.
3. Participant must not change any default parametersdefined while they will be using VISSIM
software except the Green time, cycle length and the phase plan for the signals
4. The average network speed should be in between 20km/hour and 80 km/hour for the whole
network.
5. Participants are allowed to use the features of vehicle prioritization and traffic signal for smooth
traffic flow for the network.
6. No unrealistic vehicle behavior must be seen in the simulation e.g. vehicle collision or one
vehicle running over the other.
7. The participants can’t use the feature of making flyover in the network design.
8. Under the limitation of the student version of the VISSIM software the simulation may only run
for 600seconds.
General Rules
1. The organizers will reject incomplete, inconsistent or improper documents and designs.
Furthermore, the organizers will not return submitted documents and designs.
2. The decision of the jury shall be final and binding.
3. All entrants are regarded as having a full understanding of the regulations for the competition
and as being willing to comply with every rule.
4. The organizers reserve all rights to change any or all of the above rules as they deem fit. Change
in rules, if any, will be highlighted on the website and notified to the registered participants.

Team SpecificationsA team may consist of a maximum of 3 members. Students from different educational institutes may
form a team.
Eligibility
All students with a valid identity card of their respective educational institutes are eligible to participate.
Certificate policy
1. Certificate of Excellence will be given to all the winners.
2. Certificates of Participation will be given to all the teams whose get into the final round of the
competition. The teams which get disqualified due to disobeying any of the competition rules
will not be considered for the certificate.
Judging Criteria
Qualification Round: The judging for qualification round will be subjective and will mainly depend upon
following parameters:
1. Average Network Speed / Average Travel Time
2. The no of vehicles that are get passed through the network in the simulation type
3. Final Round: Top few winning entries will be called here in Techfest 2011 from 7
th-9
thJanuary, 2011 for
the final round of competition with a modified problem statement using student version of the VISSIM
software. The judging for the final round will depend upon its problem statement.
