A smart traffic management is a wide topic of research. Many modifications can be made to make the urban traffic flow smoothly on the roads. The increasing utilization of private vehicles and public transportation due to advancement of technology causes hectic traffic complexities for the civilians across the globe. The problem of traffic congestion is an everyday problem for human resource and therefore hinders the growth of the country by affecting its productivity as well as economy. Moreover, the traffic signaling systems have predetermined fixed operational time which fails to manage the traffic density changing with time and thus, long traffic queues are formed at the road crossings resulting in increased pollution and waiting time. In this paper, we tried to provide solution to reduce the waiting time at road crossings while keeping in mind the importance of time of the citizens as well as the emergency service providers (such as EMS i.e. Emergency Medical Services, Fire and Rescue Services, etc.). The presented system in this paper is based on smart traffic congestion control system that will automatically set the signal time based on the measured values of vehicle density on road lanes. However, the manual changes can also be made to traffic signals for efficient traffic management in case of emergencies. This paper presents an idea of traffic management using internet of things (IOT). The Internet of Things (IoT) refers to a system of internet-connected objects that are able to collect and transfer data over a wireless network without human intervention. This technology provides an effective communication between different signals and helps in collection of data thereby providing an IoT based smart traffic management system in terms of its automated tracking, monitoring and controlling of vehicles and its data processing.

In this project “RFID based Car Parking System” we have shown the concept of an automatic car parking system. As in the modern world everything is going automatic we have built a system which will automatically sense the entry and exit of cars through the gate and then display the number of cars in the parking lot.
Check-ins and check-outs will be handled in a fast manner without having to stop the cars so that traffic jam problem will be avoided during these processes. Since there won't be any waiting during check-ins and check-outs the formation of emission gas as a result of such waiting will be avoided. Therefore, by this project we develop a parking system for an organization to have automated parking system for making best use of space, decreasing the man power and providing authentication for the vehicles from avoiding the theft.
Even we can set a maximum capacity of cars .We have developed a microcontroller which is used to sense the movement of cars and depending upon whether there is a capacity of cars to enter, it either opens the gate or not. It is also possible to open a gate when any car enters in the parking lot or close the door when a car exits from the parking lot with help of RFID.
There are two sets of sensors: one on the first gate (entry gate) and one on the second gate (exit gate). When a car arrives at the door the microcontroller receives the signal from the entry sensors and then checks whether there is a capacity of cars to be accommodated. Simultaneously it will also display the number of cars present in the parking lot on a LCD screen and also opens the gate. When a car moves out of the parking area the microcontroller reduces the count displayed accordingly and also closes the gate .The sensing of entry and exit of cars is done with the help of Infrared transmitters and receivers. Before the door the Infrared transmitter is mounted on one side and the receiver is placed directly in front of the transmitter across the door. When a car arrives the Infrared beam is blocked by the car and the receiver is devoid of Infrared rays and its output changes. This change in output is sensed by the microcontroller and accordingly it increments the count and opens the door if there is some capacity. The procedure for the exit of the cars is similar as the entry.

: This paper is aimed at designing a density based dynamic traffic signal system where the timing
of signal will change automatically on sensing the traffic density at any junction using the IoT technology. Traffic
congestion is a severe problem in most cities across the world and therefore it is time to shift more manual mode
or fixed timer mode to an automated system with decision making capabilities. To optimize this problem, we have
made a framework for an intelligent traffic control system. Sometimes higher traffic density at one side of the
junction demands longer green time as compared to standard allotted time. We therefore propose here a
mechanism in which the time period of green light and red light is assigned on the basis of the density of the
traffic present at the time. This is achieved by using LIDAR sensors.

With the vast growing influx of population in the developed, industrially and technologically sound urban cities, an urgent need to make the cities smart is surmounted. The cities are made smart utilizing data sharing, artificial intelligence, machine learning, analytics, and thousands of RFID tags and sensors. One of the significant concerns of today's smart cities is the growing need to manage the vehicles on-road as well as to create sufficient and well-managed parking lots to prevent urban areas from traffic congestion. This leads to a call for highly automated parking management system self-sufficient in guiding the driver to an available parking space in the nearby area. This project deals with the prototype of the smart parking system (S.P system). The proposed smart parking system collects the parking availability status and assists drivers in finding parking space that effectively reduces the traffic problems and mismanagement across the cities to a great extent.

Living in cities can be troubling
1. Subhash kumar ASSIGNMENT-03
(18btcse009)
Living in cities can be troubling. Urbanization is always expanding, and
traffic in cities is becoming heavier every day. The UN Department of
Economic and Social Affairs (UN DESA) predicts that all of the increase
to the world’s population will live in urban areas. This increase is
predicted to be as much as 68% by 2050. The population growth is not
only a pressing issue for the government but a tangible daily reality for
most citizens.
Smart parking development implies an IoT-based system that sends data
about free and occupied parking places via web/mobile application. The
IoT-device, including sensors and microcontrollers, is located in each
parking place. The user receives a live update about the availability of
all parking places and chooses the best one.
The main idea was the creation of smart parking using the Internet of
Things and ultrasonic sensors, where available parking places could be
displayed in a web application.
Used IoT ecosystem:
Hardware: ESP8266 microcontroller, HC-SR04 distance measurement
sensor
Network: MQTT protocol
Cloud & Analytics: Amazon Web Services: AWS IoT, AWS Lambda
Used Programming Languages: Micro-Python, Python, JavaScript
2. Subhash kumar ASSIGNMENT-03
(18btcse009)
User Interface: JavaScript-based web application.
The IoT device consists of an ESP8266 microcontroller and an HC-SR04
distance measurement sensor. The sensor periodically measures the
distance and transmits this data to the microcontroller, which is
connected to AWS IoT service via the MQTT protocol.
Periodically, the device sends measurements to the cloud where they are
stored in AWS IoT shadow as a sensor state. A sensor detects a parked
car by measuring the distance to the nearest obstacle—in our case, to
the bottom of the car. The state can be “occupied” if the distance is in
the range of 100mm – 500mm, “free” if the distance is more than 500mm
and “dirty” if the distance is less than 100mm, which means that the
sensor may be unclean. All of these values can be easily configured.
These values represent both free and occupied parking lots.
In our case, if the sensor detects nothing up to 50 cm, the status is set
to “free” and is shown to the user.
The “occupied” range is between 10 and 50 cm.
3. Subhash kumar ASSIGNMENT-03
(18btcse009)
Below 10 cm, the status is “dirty”. It means the sensor might be covered
with mud or an obstacle, and requires checking.
When a driver accesses the system via web application, a signal is sent
to the Lambda function. It reads the sensor state values from AWS IoT
shadow and displays parking spaces depending on the state. Green
colour – free space, red colour – occupied space, yellow colour –
pollution.
For now, this particular solution may be used for MVP and POC (proof
of concept).
The building of a full-fledged IoT based smart parking system will be
different. Hardware, software and firmware selection will depend on the
size of the specific parking area and the number of parking slots.
Mobile and/or web application features also play a big role in the IoT
system architecture. If business requirements show demand for a smart
parking development, a more advanced application might be created.
All the hardware should always be selected by the IoT specialist.
Depending on the IoT system architecture, developers will select the
most suitable hardware. In some cases, it’s better to use gateway
and LPWAN for IoT sensors, for others it may not be.
The improvement of smart parking system depends on business needs.
Taking into account retail and healthcare technology trends, smart
parking might take priority. Returning to our smart parking solution, the
main features that might be improved are:
LoRaWAN protocol will increase the autonomous operating time of a
smart parking system. Due to LoRa Alliance’s specification, the
LoRaWAN protocol is optimized for low power consumption, which means
that you don’t need to change batteries more often than once every 2-5
years. Furthermore, it is designed to scale from a single gateway
4. Subhash kumar ASSIGNMENT-03
(18btcse009)
installation up to large global networks with billions of devices. Thus, it
would be a good idea to apply this or any LPWAN protocol for a smart
park.
Data Science and Computer Vision technologies based on video stream
are also a perfect match for IoT-based innovations. On the subject of
smart parking development, Data Science, Machine Learning and
Computer Vision might be applied for car number recognition.
This feature allows:
Automatic gate opening, if the car belongs to a given park
Navigation of cars to available and suitable parking slots
Sensor integration is also a good upgrade for smart parking systems.
The most applicable are:
1. Ultrasonic sensors
Ultrasonic sensors measure distance by using ultrasonic waves in time
between the emission and reception. Advantages: high accuracy of the
sensor. The disadvantages: the probability of sensor contamination.
2. Electromagnetic field sensors
Electromagnetic field sensor is a small-scale microelectromechanical
system device for detecting and measuring magnetic fields. The solution
is based on the change of the electromagnetic field as the metal
mechanisms approach one another.
3. Infrared sensors (IR sensor)
An infrared sensor is an electronic device that emits in order to sense
some aspect of its surroundings. An IR sensor can measure the heat of
5. Subhash kumar ASSIGNMENT-03
(18btcse009)
an object as well as detect motion. An IR sensor works in a similar way
to ultrasonic sensors.
Custom mobile and web IoT applications might be developed
depending on business needs. The function of a parking slot order
may be a killer feature for mobile/web apps. If a parking area is a
few kilometres long, an integrated AR navigation may help drivers not
to get lost looking for own car.
All the features mentioned above are not the limit of the technology.
The more technology innovations we implement, the more features we
can add. For most cities, smart parking is still evolving technology.
Only by implementing new ideas can we make smart solutions like
these available and use them to improve our everyday life.
