Transportation planning is an integral part of overall urban planning and needs systematic approach.
Travel demand estimation is an important part of comprehensive transportation planning process.
However, planning does not end by predicting travel demand.
The ultimate aim of urban transport planning is to generate alternatives for improving transportation system to meet future demand and selecting the best alternative after proper evaluation.
Presentation from ACM AVI 2012 in Capri, Italy on gravity navigation. Gravity navigation (GravNav) is a family of multi-scale navigation techniques that use a gravity-inspired model for assisting navigation in large visual 2D spaces based on the interest and
salience of visual objects in the space. GravNav is an instance of topology-aware navigation, which makes use of the structure of the visual space to aid navigation. We have performed a controlled study comparing GravNav to standard zoom and pan navigation, with and without variable-rate zoom control. Our results show a significant improvement for GravNav over standard navigation, particularly when coupled with variable-rate zoom. We also report findings on user behavior in multi-scale navigation.

Identification of Factors to Improve Public Transit Services (A Case Study of...Dr. Amarjeet Singh
This research presents studies on a segment of highway to determine the quantitative factors that inuence transit services. Travel time and delay study is one of the method to determine quantitative factors. Tour time is described as the average period of time required to journey from one region to some other. Total departure time consists of gadgets which include total working time, places and general delay time. The examine section was done in Prithvi chowk to Tal chowk of Prithvi Highway which is turned to be 12.5 km long.
Additionally, it has been found that the principle variables affecting travel time are: postpone time because of forestall selecting and choosing up passengers, bus model and bus size.32 trips public transport carrier and a 10 trips non-public automobile journey have been held during peak hours. Models are developed the use of SPSS software to become aware of the relationship between the causes of delays and the overall-time delays. Travel time and learning delays can help reduce the number of private vehicles operating and increase the number of public vehicles in order to reduce congestion and improve the e efficiency of the public transport system. It turned into determined that there was a full-size distinction in tour time among the use of the public transit services and the car.
“Mode choice between Roadway and Waterway ... • Roadway and waterway are plays an important role in our country’s society and economy as well as in our multi-modal transportation system. Its low expenses and high accessibility, as compared with other alternatives, amplifies a great demand

CFD Simulation of By-pass Flow in a HRSG module by R&R Consult.pptxR&R Consult
CFD analysis is incredibly effective at solving mysteries and improving the performance of complex systems!
Here's a great example: At a large natural gas-fired power plant, where they use waste heat to generate steam and energy, they were puzzled that their boiler wasn't producing as much steam as expected.
R&R and Tetra Engineering Group Inc. were asked to solve the issue with reduced steam production.
An inspection had shown that a significant amount of hot flue gas was bypassing the boiler tubes, where the heat was supposed to be transferred.
R&R Consult conducted a CFD analysis, which revealed that 6.3% of the flue gas was bypassing the boiler tubes without transferring heat. The analysis also showed that the flue gas was instead being directed along the sides of the boiler and between the modules that were supposed to capture the heat. This was the cause of the reduced performance.
Based on our results, Tetra Engineering installed covering plates to reduce the bypass flow. This improved the boiler's performance and increased electricity production.
It is always satisfying when we can help solve complex challenges like this. Do your systems also need a check-up or optimization? Give us a call!
Work done in cooperation with James Malloy and David Moelling from Tetra Engineering.

Immunizing Image Classifiers Against Localized Adversary Attacksgerogepatton
This paper addresses the vulnerability of deep learning models, particularly convolutional neural networks
(CNN)s, to adversarial attacks and presents a proactive training technique designed to counter them. We
introduce a novel volumization algorithm, which transforms 2D images into 3D volumetric representations.
When combined with 3D convolution and deep curriculum learning optimization (CLO), itsignificantly improves
the immunity of models against localized universal attacks by up to 40%. We evaluate our proposed approach
using contemporary CNN architectures and the modified Canadian Institute for Advanced Research (CIFAR-10
and CIFAR-100) and ImageNet Large Scale Visual Recognition Challenge (ILSVRC12) datasets, showcasing
accuracy improvements over previous techniques. The results indicate that the combination of the volumetric
input and curriculum learning holds significant promise for mitigating adversarial attacks without necessitating
adversary training.
Courier management system project report.pdfKamal Acharya
It is now-a-days very important for the people to send or receive articles like imported furniture, electronic items, gifts, business goods and the like. People depend vastly on different transport systems which mostly use the manual way of receiving and delivering the articles. There is no way to track the articles till they are received and there is no way to let the customer know what happened in transit, once he booked some articles. In such a situation, we need a system which completely computerizes the cargo activities including time to time tracking of the articles sent. This need is fulfilled by Courier Management System software which is online software for the cargo management people that enables them to receive the goods from a source and send them to a required destination and track their status from time to time.
2. In a transportation study, it is often necessary to know the
exact origin and destination of the trips. The information
yielded by O-D survey includes land-use of the zones of
origin and destination, household characteristics of the
trip making family, time of the day when journeys are
made, trip purpose and mode of travel.
INTRODUCTION
Origin is defined as the place where the trip begins and
destination is defined as the place where the trip ends.
Origin-Destination (OD) studies are an important tool
for transportation Professionals. OD studies are
conducted to understand the pattern of the movement
of Persons and goods in a particular area of interest
during a particular period of time (Wang, 1997).
3. The specific uses to which o-d survey data
To determine the amount of by passable traffic that
enters a town and thus establishes the need for
bypass.
To develop trip generation and trip distribution models
in transport planning process.
To determine the extent to which the present highway
system is adequate and plan for new facilities.
To assess the adequacy of parking facilities and plan
for future
4. METHODS OF ORIGIN AND DESTINATION
STUDY
In order that may flow as smoothly and safety as
possible, it may become necessary to collect data as to
where the traffic came from and where it is going. That is
the purpose of this type of study. The information
gathered may be used to modify the circulation pattern
or assist in other long range planning activities. These
studies are time consuming and rather complex. They
also require the cooperation and assistance of the
public.
5. There are 6 different methods of conducting origin and
destination studies.
License plate mail –out method
Road side interview
Mail- back postcard surveys
Phone surveys
Cell phone, and global positioning system (GPS)
receiver
6. License plate mail –out method
The licence plate mail-out survey involves recording
licence plate numbers of vehicle on a selected
roadway, tracing vehicle ownership, and mailing a
survey to owner’s .
There are two different methods to obtain the licence
plate number: taking a photo / video or manually
recording the tag on vehicle. photo or video are often
used for high volume highways and the manual
recording method can be used for low and medium
volume road way .
This method has no disruption to normal traffic flow
because it does not require vehicles to be stopped to
receive the survey
7. Road side interview
Road side interview involves directing vehicles into a
designated interview area and asking a series of short
questions.
This technique has been widely used for both truck
and auto trip collection because it has a very high
response rate , good sampling control, boar
geographic coverage , and normally result in complete
information.
The dis advantage of this method is that it generally
requires more personal and traffic control at survey
sites. Sometimes, it may be difficult to implement due
to traffic disruption especially in urban areas.

11. Mail- back postcard survey
Mail- back postcard surveys are often used when
traffic volume is high .compared to the road side
interview , postcard survey have less impact on traffic
post card with a brief questionnaire can be
distributed to motorists either at rest areas on the
interstates or at signalized intersections or gas
stations where they normally stop.
The advantages of this technique are that postcards
can be distributed quickly and with fewer personnel
than are required for interviews.
The disadvantage is that a higher number of vehicles
must be sampled to obtain an adequate number of
completed surveys because of the lower response
rate of less than 30 percept .
12. Phone surveys
Telephone surveys typically have a higher response
rate mail –back, and lower response rate than road
interview.
This method has no disruption to traffic flow and no
risk for survey personnel. However, it involves a great
effort of identifying the appropriate contact person and
phone number .
This method is often used for household travel
surveys, and seldom used O-D survey.
13. Cell phone, and global positioning system
(GPS) receiver
Cell phone tracking technology currently and
presumably can only provide the data on phone (the
owners) movements as cell phones transition from one
cell tower to another cell tower. The phones must be on,
although not in use.
The data from cell phone movements can possibly
generate origin –destination data needed for support of
planning models. However, to date, this technology has
not been used for an O-D study.
Widespread utilization of GPS receivers for O-D data
collection is currently cost prohibitive, especially for
large rural and urban areas.

15. CASE STUDY
Objective of the present study
To judge the adequacy of existing routes and to use in
planning new network of roads.
·To plan transport system and mass transit facilities in

Havanur circle is one of the busiest junctions in
Bangalore; this intersection makes a way to outer ring
road, magadi road and Mysore road. The following
measures are taken to reduce traffic congestion
·Short term measures:
·Alter the timings of the HAVANUR junction traffic
signals and review the traffic
And pedestrian phases to ease congestion at
certain times of the day.
·Alteration of signal timings during off peak hour
period.
·Movement of heavy commercial vehicles should be
avoid at day time and allow at night time.
22. ·Long term measures:
·Channelization of junction like providing free left on
both sides of the junction.
·Extra widening of carriage width by reducing the
footpath width of KHB of Vijayanagar to Shankara
mutt.
·Underpass should be provided from Westoff chord
road to Basaveshvaranagar 4th block.
·Models like modal split, travel time demandcan be
generated.
23. CONCLUSION
Origin is defined as the place where the trip begins and
destination is defined as the place where the trip ends.
Origin-Destination (OD) studies are an important tool for
transportation Professionals. OD studies are conducted
to understand the pattern of the movement of Persons
and goods in a particular area of interest during a
particular period of time. And used for many purpose like
to determine the extent to which the present highway
system is adequate and plan for new facilities
