Reader's Response Second Draft

 In the article “IoT based Smart Parking Systems for Smart Cities”, hIOTron(2020), claims that effective management of parking space will prevent traffic congestion. Smart parking utilizes sensors installed on lots to detect lot availability which can be used in offices and shopping malls. Occupants can book the lot in advance while receiving real time accessibility and when the sensors confirm a vacant lot, the car will be parked automatically. For an IoT solution, it must make it easy to transfer field data to the cloud at low cost and increased ROI which is a challenge because there might be real upfront costs as in-ground sensors can incur additional cost for two parking systems. Smart parking authentication is done using an RFID tag and data collected is reserved in the cloud. The app would find a vacant lot and send the location to the user after registration is completed. Optimal parking is achieved with minimal time and effort while enhancing the user’s experience. Smart parking system helps to reduce carbon emission as well as reducing traffic congestion. While I agree that there are many advantages to a smart parking system, it can be costly in terms of the initial cost.

There are many advantages to smart parking systems. One of which includes reducing the carbon emission. In this urbanized city, there is an increase in the number of cars on the road which seriously affects the quality of the traffic as occupants’ have to search for available parking lot which increases the traffic volume. Muhammad Alam (2018) states that in Los Angeles, the search for available parking took 178,000 litres of fuel (which is enough to circle the world 38 times) and produced 730 tons of carbon dioxide.  This shows the heavy impact it has to the drivers’ and mother earth. With the implementation of smart parking, users can pre book the parking slot which reduces the need to look for a parking slot while reducing traffic as fewer cars are needed to drive around in search of an open parking space. 

 

Secondly, a research has shown that smart parking systems has benefits to stakeholders. Smart parking applications are particularly helpful in cities with high population and traffic densities. According to Shubhankar Gautam (2018), one city that has benefitted greatly from smart parking technology is San Francisco. After the technology has been implemented in the city, the time taken to find a parking space reduced by 43%, miles were driven to get to a parking space dropped by 30% and greenhouse gas emissions dropped by 30%. This shows that smart parking system reduces the stress for users to find a parking lot as the time needed for them to find a parking lot with smart parking is reduced, the use of fuels have also decreased as users do not need to drive around to search for a parking lot with the convenience of an App. 

 

Lastly, automated parking is also used in the smart parking systems whereby occupants’ do not need to park their own cars after finding a desired lot. Computer controlled mechanism are used in automated parking, where the safety features are available. After the user has paid for the parking, by using RFID technologies, the payment is made by Automated Vehicle Identification (AVI) tag. This RFID technology and mobile devices are contact less methods, where the contact methods are smart cards, debit cards and credit card. The car will be shifted by an elevator or a carousel system up to the storage floors and parked into a proper space with security guarantee.

In conclusion, there are many advantages to smart parking systems from minimizing the time needed to find a parking lot to reducing traffic and green house gas emissions. The only challenge of smart parking is the cost which however is not an issue in Singapore as Singapore is an urbanized city with adequate funds.

Formal Letter

  Subject: Self introduction   Dear Prof Brad, My name is Loh Wan Xin Zann from your effective communication class and my purpose of writing this letter is to allow you to know me better. I recently graduated from Temasek Polytechnic with a Diploma in Green Building and Sustainability. To be frank, I did not have much interest in engineering during my first two years of study in the course as I was more inclined to learning business. My interest in engineering developed when I was attached to a facilities management company during my internship where I was exposed to do Green Mark certification for school buildings which is why I decided to pursue my studies in Sustainable Infrastructure Engineering (Building Services) in SIT. Aside from academic interests, I utilize my free time by attending street jazz dance classes as it has always been my hobby since young and it helps me to release my stress by sweating it out. A communication strength I believe that I possess would be my

Annotated Summary

  Hashimoto, K., Kawaguchi, C., Matsueda, S., Morinaka, K., & Yoshiike, N. (1998, April 1). People-counting system using multisensing application. https://www.sciencedirect.com/science/article/pii/S0924424797017159 In this article, Hashimoto, Kawaguchi, Matsueda, Morinaka and Yoshiike (1998) focus on the applications of the people counting sensor by explaining the components and how it processes. The people-counting system is equipped with a multi-element infrared sensor which is made of PbTiO3 ceramics to achieve non-contact and non-blocking real-time counters with high accuracy. The sensor digital output and human information sensor uses a pyroelectric array detector to detect the direction of the movement and number of people. The counting sensor with eight-element array detectors is set up on the ceiling in the centre of the door and the sensor arrays are parallel to the movement directions of the occupants. The sensor on the ceiling detects the heat from the floor, and the s

Task 3: The Importance of communication skills for engineers

 "Employers identify communication as one of the basic competencies every graduate should have, asserting that the ability to communicate is valuable for obtaining employment and maintaining successful job performance." Sherwyn Morreale, Michael Osborn & Judy Pearson, Professors of Communication (2000)  Explanation:  I believe that communication is the key to success. The act of communicating helps to connect with the other person. In the workforce, communication is extremely important in terms of both verbal communication and written communication as employees often have to work with different clients for projects in the engineering industry. Having good communication skills will help to boost the productivity of work whilst maintaining strong working relationships in an organisation.
