Driving too fast is one of the most prevalent factors that contribute to traffic crashes. In school zones,
staying alert and obeying the posted speed limit especially during the school period are imperative for public safety,
particularly involving children. Encouraging motorists to travel at safe speeds through the installation of yellow
transverse bars at Seri Sabak Uni School and Pintas Puding School was found to be ineffective. Drivers were
observed to have violated the 30 km/h speed limit and more seriously, driven over the speed limits of adjoining
roads. Consequently, speed camera warning signs were erected as a pre-emptive measure to curtail speeding
problems in the school zones. From impact studies carried out to measure the effectiveness of these signs, it was
found that the speed camera warning signs were also not able to change driver behavior.
Driver`s Steering Behaviour Identification and Modelling in Near Rear-End col...TELKOMNIKA JOURNAL
This paper studies and identifies driver`s steering manoeuvre behaviour in near rearend
collision. Time-To-Collision (TTC) is utilized in defining driver’s emergency threat
assessment. The target scenario is set up under real experimental environment and the
naturalistic data from the experiment are collected. Four normal drivers are employed for the
experiment to perform the manoeuvre. Artificial Neural Network (ANN) is proposed to model the
behaviour of the driver`s steering manoeuvre. The results show that all drivers manage to
perform steering manoeuvre within the safe TTC region and the modelling results from ANN are
reasonably positive. With further studies and improvements, this model would benefit to
evaluate the driving reliability to enhance traffic safety and Intelligent Transportation System.
The spectacular growth of the automobile as one of the most convenient modes of travel has brought in its wake frustrating problems of parking, accidents, delay, congestion, etc. It is no longer sufficient to build roads of adequate structural strength to cater to the needs of vehicles, but it is equally important that the safe, efficient and comfortable movement of traffic and other road user is ensured on these roads. Highway intersections are nodes of road networks and accident - prone locations. They are the places where vehicles coming from different approaches and moving towards different directions interact and conflict with each other. Due to the conflicts from all users, more traffic crashes could happen at unsignalized intersection as compared with roadway segments. This study is fully based on the existing conditions of unsignalized intersection, including geometric design, sight distance, traffic control devices etc. The problems of parking, accidents and delay are also prevailing in the area under our study i.e. intersection at 26th mile. The intersection is an unsignalized one and therefore, the chances of accidents during the peak hours are very high. Since, it is a meeting point of a national highway and a state highway, the variation in the design speed of both roads also interrupts the traffic flow. Our study on the intersection at 26th mile mainly aims at improving the geometrical as well as the safety features of the intersection like accident control by signal installation, incorporation of proper sight distances, uninterrupted traffic flow without causing crashes, delay, etc.
The rapid increase in the occurrence of road accidents in Nigeria requires the
deployment of real time techniques that is equipped to reduce one of the critical
factor that have been identified by the Federal Road Safety cooperation of Nigeria
(FRSC) that constitute the major cause of road accidents which is over speeding. This
was achieved through the design and implementation of real time vehicle speed
monitoring system using cellular signal along the travelled path. A data acquisition
device was developed to capture in real time the signal strength and geospatial data
(longitude and latitude) along the travel path which is used in determining the speed
of the moving vehicle. The acquired data was correlated with data obtained from
standardize equipment to establish the integrity of the data, the data was then used to
develop the algorithm by obtaining equation for the path-loss gain in terms of signal
strength against distance. Equation for the base stations covering a distance of 10km
were obtained for analysis. Consequently from the equation, the distance from two
locations along the route can be determined from corresponding signal strength
values, the average speed results for the drive test, new Model and using Latitude and
Longitude are compared as followed 88.05km/hr, 75.67km/hr and 88.2km/hr

Study of Traffic Volume and Level of Service of Panjab University, ChandigarhIJERA Editor
A significant effort has been made in order to study the Traffic Volume of Panjab University Campus, Chandigarh. Established in 1882, Panjab University is one of the oldest universities in India. As one of the most renowned Universities in India, Panjab University itself attracts a lot of vehicular population. The Panjab University itself becomes a major traffic generator in a way. Campus is large and contains places to work, learn, socialize and live each with its own trip purpose. In recent years, usage of automobiles on campus has increased considerably. In addition to going to class, students also are likely to use vehicles for employment, recreation, shopping and social activities. The objective of the study is to analyze the prevailing traffic conditions on the University roads. Traffic Volume study is carried out in the campus and existing level of service is calculated.Due to mixed nature of traffic it gets difficult to accommodate all the kinds of traffic on these roads. The basic problem arises during the peak hours of the day when the traffic volume is highest on the road. The volume study were done at Gate no.1 and Gate no. 2 which are the major entry points in the University. The data was analyzed for the peak hour of traffic.

ANALYSIS OF NOISE LEVEL DUE TO VEHICLE TRAFFIC ACTIVITIES ON THE KAMIZAUN ROA...IAEME Publication
Noisy is a sound that disturbs the comfort of the community. Variable sources of
noise can come from humans, household appliances, machinery, other activities both
inside and outside the room, land, sea and air transportation vehicles. Noisy
originating from land transportation activities, one of which comes from motorized
vehicles that cross the road. Noise is generated by the sound of a vehicle engine,
friction between the wheel and the road surface, horn sound, vehicle speed and driver
behavior. Communities are sometimes less aware of the impact caused by noise due to
traffic activities. Health can be disrupted, one of them is hearing loss. It is not
realized that in fact other than residential areas there are public facilities around the
road which are harmed by the noise source, namely the education area. Kamizaun
Road is a road that is in the use of educational land. Traffic activity on Jalan
Kamizaun certainly has an influence on students and students who are undergoing the
learning process. When the teaching and learning process takes place students,
students, teachers and lecturers need peace. Kamizaun Street is also not far from
Merauke Mopah Airport. When air traffic activities start operating in the morning,
the sound produced by airplanes is quite disturbing in the classroom. This type of
research is quantitative descriptive. This study measures how much noise levels occur
as a result of traffic activities of motorbikes, light vehicles and heavy vehicles. In
addition it also measures the speed of the vehicle which affects the noise level. The
results showed that the traffic volume on Jalan Kamizaun during the morning,
afternoon and evening peak hours was 1356 vehicles, 1308 vehicles and 1602
vehicles, respectively. The highest vehicle speed is 30.3 km / h and the lowest is 18 km
/ hr. The highest noise level is 78.3dB and the lowest is 65dB. The noise level value
has exceeded the threshold value for the school area which is 55dB
Proposed smart traffic signal control in brunei darussalamAndino Maseleno
This paper presents proposed SMART (Systematic Monitoring of Arterial Road Traffic Signals)
traffic signal control in Brunei Darussalam. Traffic congestion due to stops and delays at traffic light signals
has much been complained about in Brunei Darussalam as well as across the world during the recent years.
There are primarily two types of traffic signal controls in Brunei Darussalam. The most common one is
the fixed or pre-timed signal operation traffic light and the other one is the actuated signal operation traffic
light. Although the actuated signal control is more efficient than the fixed or pre-fixed signal control in the
sense that it provides fewer stops and delays to traffic on the major arteries, the best option for Brunei
Darussalam would be to introduce SMART traffic signal control. This type of traffic signal uses artificial
intelligence to take the appropriate action by adjusting the times in real time to minimise the delay in the
intersection while also coordinating with intersections in the neighbourhood. SMART signal simultaneously
collects event-based high-resolution traffic data from multiple intersections and generates real-time signal
performance measures, including arterial travel time, number of stops, queue length, intersection delay, and
level of service. In Brunei Darussalam, where we have numerous intersections where several arterial roads
are linked to one another, The SMART traffic signal control method should be implemented.
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.

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.

Automobile Management System Project Report.pdfKamal Acharya
The proposed project is developed to manage the automobile in the automobile dealer company. The main module in this project is login, automobile management, customer management, sales, complaints and reports. The first module is the login. The automobile showroom owner should login to the project for usage. The username and password are verified and if it is correct, next form opens. If the username and password are not correct, it shows the error message.
When a customer search for a automobile, if the automobile is available, they will be taken to a page that shows the details of the automobile including automobile name, automobile ID, quantity, price etc. “Automobile Management System” is useful for maintaining automobiles, customers effectively and hence helps for establishing good relation between customer and automobile organization. It contains various customized modules for effectively maintaining automobiles and stock information accurately and safely.
When the automobile is sold to the customer, stock will be reduced automatically. When a new purchase is made, stock will be increased automatically. While selecting automobiles for sale, the proposed software will automatically check for total number of available stock of that particular item, if the total stock of that particular item is less than 5, software will notify the user to purchase the particular item.
Also when the user tries to sale items which are not in stock, the system will prompt the user that the stock is not enough. Customers of this system can search for a automobile; can purchase a automobile easily by selecting fast. On the other hand the stock of automobiles can be maintained perfectly by the automobile shop manager overcoming the drawbacks of existing system.
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.

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!

516 and 18, 313 vehicles was observed at Site 1 and Site
2, respectively.
RESULTS
Figure 1 to 4 show the distribution of speed
observed before and after the installation of speed
camera warning signs in both directions at the study
sites. The distribution histograms are based on 5 km/h
speed bin width, ranging between the maximum and
minimum speeds observed. From these figures, overall
speed distribution does show a good distribution of data.
Speed behaviour analysis at study sites: The
descriptive analysis conducted using data collected at
Site 1 showed that the speed distribution fell in the range
of 5 km/h and 149 km/h. Before the installation of speed
camera warning sign, speed at this site peaked between
60 to 65 km/h (Fig. 1 and 2). However, after the speed
camera warning sign was erected the speed in the Batu
Pahat to Ayer Hitam direction peaked between 70 to 75
km/h. The mean of speed observed in the Ayer Hitam to
Batu Pahat direction was 59.6 km/h and in the Batu
Pahat to Ayer Hitam direction was 60.55 km/h. The
mean speeds significantly increased by 1.4 and 7.7%
(p<0.05), respectively one month after the sign was put
up (Table 1 and 2).
Further observations revealed that, more than 90%
of the drivers violated the speed limit of 30 km/h at this
site. The study also found that, over 50% of the drivers
drove above the adjoining road segments’ speed limit of
60 km/h. Moreover, drivers of Class 3 vehicles (trailers
and buses) were found to have the highest average speed
compared with other vehicle types (refer to Table 3).

Pahat showed that most drivers had driven between 61
and 65 km/h before the installation of speed camera
warning sign. However after the sign was installed, the
peak speed reduced to between 46 and 50 km/h (Fig. 3).
The average reduction in speed post-installation was
about 10.3% (p<0.05).

In the direction from Batu Pahat to Ayer Hitam,
speed reduction was not demonstrated after the
installation of the speed camera warning sign. This is
reflected by the speed distribution presented in Fig. 4.
The mean speed increased from 60.2 km/h to 60.9 km/h.
Although the mean speed increased slightly, it was
statistically significant, with p<0.005 (refer to Table 2).
Prior to the speed camera warning sign installation,
observations on compliance with the speed limit
revealed that only 4.2 and 2.7% of drivers complied
with 30 km/h speed limit in the Ayer Hitam-Batu Pahat
and Batu Pahat-Ayer Hitam directions, respectively. It
was also found that more than 50% of the drivers drove
over the adjoining road segments’ speed limit of 60
km/h before the installation of the speed camera
warning sign (Table 4).
DISCUSSION AND CONCLUSION
The initial objective of the project was to
investigate if the presence of speed camera warning
signs can influence the speed of drivers in school zones.
School zones are considered as areas of accident risk
due to high pedestrian and motorist activity, especially
during school hours. Drivers are alerted of school zones
via the installation of school zone and schoolchildren
crossing warning signs, which are installed in
accordance with local standards and specifications.
Apart from these, speed control devices were also
introduced to reduce traffic speed through the
installation of yellow tranverse bars. However, they
were found to be not effective in reducing speeds,
especially during the peak school periods. It should also
be noted that the road along the study sites has been
identified as an accident blackspot by the Ministry of
Transportation (Mustakim and Fujita, 2011). Since the
speeds observed during school hours were statistically
indifferent during off-school hours, therefore the risk of
accidents in school zones is high at all times.
The presence of speed camera warning signs was
considered as a good way of encouraging drivers to
comply with the speed limit. However, as found in this
study, drivers did not obey the speed regulation. It is
also a cause for concern that the speeds observed after
the installation of speed camera warning signs were
found to have significantly increased. In addition, more
than 50% of the Class 1, 2 and 3 vehicles were found to
have been driven over 60 km/h.
There are several possible explanations for these
findings, the main reason being associated with the
driver’s own attitude and lack of awareness on safety in
school zones. This is supported by Abdul Hanan et al.
(2013) who studied about Malaysian drivers’ intention
5. Res. J. App. Sci. Eng. Technol., 8(23): 2315-2319, 2014
2319
to comply with speed limit in school zones. Abdul
Hanan et al. (2013) suggested that only drivers with
positive attitudes towards school zone speed limits were
likely to comply. Therefore, it can be said that the
observed drivers did not possess acceptable attitudes
and responsiveness towards road safety in school zones.
It may also be concluded that the speed camera warning
signs were ignored by drivers as they had realised that
there were no speed surveillance operations conducted
by the traffic police and that the speed camera warning
sign was probably just a dummy. In addition, no
summonses were given out as a result of speed
violation.
The road characteristics may also be a contributing
factor to the speed behavior of drivers at these study
sites. Since the schools are located adjacent of the
multi-lane arterial, drivers may have possibly over
estimated their speed as they drove on the straight and
wide lanes (3.30 m/lane). At the study sites, the effect
of reduced effective road width due to parked vehicles
during start and end of school session was not
substantial. This was due to the existence of paved and
unpaved shoulders of acceptable widths that were used
for parking and waiting. Furthermore, vehicles were
also parked at off-street locations. Since the road
environment did not change much, drivers who drove at
that particular time may have maintained or slightly
reduced their speeds before entering the school zone.
Besides, the drivers also could change lanes to avoid
barriers that reduce their speed. This study produced
results that corroborate the findings of a previous work
by Martens et al. (1997), who reported that both lane
width and effective road width can have impact on
speed behavior.
To conclude, the findings of this study is of
paramount importance that call for further action to
ensure drivers are aware about safe operating speeds in
school zones. In fact, pedestrian-related accidents are of
great concern to the Malaysian government. It can be
summed up that school zones in Malaysia with similar
characteristics may also demonstrate similar of speed
behavior. Drivers must be educated about the
importance of speed reduction in school zones in order
to reduce the risk of accidents.
