Our project is the complete study about both Spot speed studies and Speed delay time survey. This topic is a part of Transportation Engineering. This report helps you to understand this topic in detail. This report will also help you to make project on associated topics in traffic engineering. In spot speed, We discussed regarding various methods available to perform the test, Our team practically performed test and established a speed limit zone near a school. Coming to speed delay time survey, we conducted a survey at a selected stretch and came out with solutions to the problems faced by the vehicle users using that stretch.
This presentation talks about the process of Traffic & Transportation surveys, the bases of delineating Traffic Analysis Zones and the various surveys required to be carried out to understand the traffic behavior of the city.
Capacity & Level of Service: Highways & Signalized Intersections (Indo-HCM)Vijai Krishnan V
This presentation gives a glimpse on estimating the capacity and Level of Service (LOS) of highway midblock sections and signalized intersections under heterogeneous traffic conditions using the Indo-HCM 2017 Manual. It also compares the Indo-HCM LOS estimation methods with US-HCM. Some practice questions are also included.
I acknowledge the co-author Ms. Sethulakshmi G (Ph. D. Scholar, NIT Surathkal) for her valuable contribution to this presentation.

Cosmetic shop management system project report.pdfKamal Acharya
Buying new cosmetic products is difficult. It can even be scary for those who have sensitive skin and are prone to skin trouble. The information needed to alleviate this problem is on the back of each product, but it's thought to interpret those ingredient lists unless you have a background in chemistry.
Instead of buying and hoping for the best, we can use data science to help us predict which products may be good fits for us. It includes various function programs to do the above mentioned tasks.
Data file handling has been effectively used in the program.
The automated cosmetic shop management system should deal with the automation of general workflow and administration process of the shop. The main processes of the system focus on customer's request where the system is able to search the most appropriate products and deliver it to the customers. It should help the employees to quickly identify the list of cosmetic product that have reached the minimum quantity and also keep a track of expired date for each cosmetic product. It should help the employees to find the rack number in which the product is placed.It is also Faster and more efficient way.

Water scarcity is the lack of fresh water resources to meet the standard water demand. There are two type of water scarcity. One is physical. The other is economic water scarcity.
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.

Estimation of Average Daily Traffic (ADT):
From Survey data,
Group 1: 1263 PCU/hr
Group 2: 1480 PCU/hr
Group 3 : 1455 PCU/hr
Group 4: 1772 PCU/hr
Group 5: 1533 PCU/hr
Group 6 : 1722 PCU/hr
Estimated 24-hours volume for Thursday using HEF (Hourly expansion factor) = (1772*18.80+1533*17.11+1722*18.52)/3
= 30478.22
From 24- hours volume for Thursday estimated volume for the work using DEF* (Daily expansion factor) total 7 days volume
= 30478.22*7.012
= 213713.278
So,
ADT ( 24 hours volume) West to East direction= 213713.278/7
= 30530.47 PCU = 30531 PCU (Rounded)

24. Limitations:
This volume study was practiced by un-skilled enumerators, which may lead to some error in data
collection process.
Data were collected for 30 minutes by each group, although it is assumed that the data collected for three
hours actually it is counted for only one hour which may not represent the hourly fluctuation of traffic.
AADT was calculated using expansion factors. These expansion factors established based on data collected
in a rural road of Sweden, the actual daily expansion factors will be much different from what is used. So
they will not give actual ADT.
Data collected by manual method of counting, which is unreliable and irreversible
Recommendation:
Trained and skilled enumerators should collect data which is first requirement of Manual counting
Automatic counting system should be introduced for more reliable data.
Actual expansion factor should be introduced for Dhaka city
For design purpose minimum 3 days Data should be collect.
Before final survey reconnaissance survey or pilot survey is necessary.
25. Special Observation:
All the procedure, methods, equipments were
recommendation from AASHTO(American Association
of State Highway and Transportation Officials). As the
roadway condition, vehicle types, users, surrounding
areas, weather all the things are different from the
AASHTO code, so we should develop our own code or
follow the neighboring country’s code.
