Swift Route Navigator is an advanced model that can detect and calculate the jam intensity of a road precisely and helps the drivers or passengers in decision making whether they should take the road or not. The Jam intensity is shown using a jam meter containing several LEDs which is situated at the beginning of a road.

As a developing nation, our country faces major issues, and the biggest one is traffic jams. Especially in Dhaka city, the traffic jam is so devastating that the government is seeing no way even with multiple mega projects. We may not solve this problem with a single project but we can somewhat ease the traffic and save people’s valuable time. Our project doesn’t aim to overhaul the entire traffic system; instead, we focus on a specific aspect – helping people find the current traffic situation at particular crossroads as well as properly distributing traffic among the roads with the same destination. We will not do it forcefully, rather than we will give the traffic information to the drivers and passengers and let them choose the easiest way for them. As people will avoid the heavy roads and choose the simple roads, the traffic will automatically be distributed properly. Sometimes, in a hurry, it’s challenging to check Google Maps for possible traffic. Our project addresses this by providing real-time traffic information using lights located at the entrance of the road for quick decision-making, especially for those who may not have time to check their phones or aren’t familiar with using Google Maps. We think it will make a huge impact on the current traffic system and people to understand the condition of the road in their crucial time. Identify the applicable funding agency here. If none, delete this.

Ultrasonic sensors work by sending out a sound wave at a frequency above the range of human hearing. The sensor's transducer acts as a microphone to receive and send the ultrasonic sound. Our ultrasonic sensors, like many others, use a single transducer to send a pulse and to receive the echo.
A light-emitting diode (LED) is a semiconductor device that emits light when current flows through it. A LED has a positive and a negative point. The positive point is connected with the VCC pin of Arduino and the negative point is with the GND.
An infrared sensor is an electronic device, that emits to sense some aspects of the surroundings. An IR sensor can measure the heat of an object as well as detect the motion. These types of sensors measure only infrared radiation, rather than emitting it which is called a passive IR sensor. Usually, in the infrared spectrum, all objects radiate thermal radiation.
Servos are controlled by sending an electrical pulse of variable width, or pulse width modulation (PWM), through the control wire. There is a minimum pulse, a maximum pulse, and a repetition rate. A servo motor can usually only turn 90° in either direction for a total of 180° movement. The motor is connected to the gear system, which reduces the motor speed increases torque and provides feedback to the potentiometer.
A jumper wire is an electric wire that connects remote electric circuits used for printed circuit boards. By attaching a jumper wire on the circuit, it can be short-circuited and short-cut (jump) to the electric circuit.
A breadboard, solderless breadboard, or protoboard is a construction base used to build semi-permanent prototypes of electronic circuits.

Jam Measurement: The implementation logic is simple and realistic. The goal is to measure the length of blockage of a road. Here people don’t need the blockage length in meters or other similar kinds of units. They just need a minimal measure by which they can understand how much of the road is blocked. So, we decided to divide the roads into three layers. Number of blocked layers indicates the intensity of the jam. We placed an ultrasonic sensor in each layer. The sensors record the distance for two seconds and compare all the values. If the values are within the length of a single lane and the same, then it is clear that the layer of the road is blocked. Because the same distance means no vehicle is moving. And it is opened otherwise. Then we will enlighten the LED corresponding to its layer. There are some cases also . If the first layer is open but the second layer is detecting a jam then the light of the second layer will not be enlightened. Because the road can't be opened from the mouth but blocked in the middle. This case will be possible if a vehicle breaks in front of the ultrasonic sensor due to some unexpected reason. One stopped vehicle will not create a jam so the meter will not show any jam. This logic is also applicable to the third-layered sensor.

Bus Stand Barricade: The bus stand is a distinct lane beside the main road. It has a fixed capacity and can not contain more. So, we created a system that can measure if the capacity is full or not. If the capacity is full then a barricade will close the entrance of the bus stand. No more buses can enter until any of the buses leave. For this, we planted some IR sensors that will detect the presence of a bus. If a bus is present in front of an IR sensor then the sensor will return value 1. If all the values of IR sensors are 1, then the barricade will come down and close the entrance. The barricade is attached to a Servo Motor. The motor rotates to put the barricade...
The future scope for this project is huge. The government is trying hard and soul to solve the problem of traffic jams. The government is building new flyovers, and expressways, establishing metro rails and stations only to solve traffic jams. As our system stores traffic information including the duration of the jam, the government will get a clear idea of the traffic and can easily analyze which needs more attention. As a result, they will have an idea about where the next mega project will be situated.

These are some sample images of our project. These photos were taken 2 days after the project show. So, they are not the same as our model.
