critical reflection

Module learning:

At the beginning of this module, I set two key goals for myself: to build the confidence to speak in front of a group and to sharpen my critical thinking skills. While I found both goals challenging, this module provided valuable opportunities for growth in each area. 

One of the most impactful lessons I learned was how to effectively use generative Artificial Intelligence (AI) tools to refine my writing. I discovered how prompting these tools could help me connect my ideas and translate them into formal academic language. Through consistent use, I gradually learned how to adopt a more polished and structured tone in my writing----something I previously struggled with. This has given me more confidence in my ability to write clearly and professionally.

Project Learning:

I had the opportunity to work with individuals whom I have never grouped before or talk to. I admit that it was daunting for me and I could not articulate my thoughts properly. I was afraid my idea may not be taken into consideration. As time progresses, I became much more comfortable. Instead of being afraid, I tried speaking up at times and actively listen to my other groupmates perspectives. This helped me grow not just as a team member, but also in terms of self-confidence and communication

Working as a team on a design proposal also pushed me outside of my comfort zone. Each group member pitched an idea, and we decided to pursue a project on 3D printing. However, as we explored the topic further, we realized we lacked the necessary knowledge about its feature and practical applications. While I was not the one who proposed our final solution of using AI, LiDAR and sonar onto traffic lights, I contributed by using ChatGPT to better understand how our idea could be adapted to the Singapore context. This helped the team clarify and develop the feasibility of our proposal.

Additionally, we had to do an elevator pitch based on our project topic on smart traffic lights. Public speaking remained a personal challenge. I often feel more nervous speaking in front of familiar peers than strangers. To improve, I started by recording myself reading from a script to evaluate my tone, pacing, and enunciation. Even then, I did not feel fully confident. Eventually, I chose to practice without a script in front of my parents, whose unfamiliarity with the topic allowed them to give honest feedback on how clearly I communicated my ideas. This process helped me become more aware of my presentation style and boosted my confidence gradually. Even if the outcome at the end was not satisfactory due to my nervousness and my voice projection being inconsistent, this preparing process has made me more confident with myself.

Final thoughts:

I recognise that building confidence in presenting is an ongoing journey. Nonetheless, this module has helped me take meaningful steps toward my goals, and I now feel more prepared to face similar challenges in the future.

Additional Final Draft Reader Response

Electric roads, also known as electrified roads, are advanced infrastructure systems that transfer electricity from the road to vehicles, enabling dynamic charging while in motion (Kumar & Yadav, 2023). This innovative technology addresses significant challenges faced by electric vehicles (EVs), such as limited battery range and lengthy charging times as mentioned by the same authors. There are three main types of electric road systems (ERS): conductive, inductive, and overhead catenary. Conductive systems rely on physical contact with electrified tracks embedded in the road, exemplified by Sweden's eRoadArlanda, which uses a movable arm to connect vehicles to an electrified rail (European Road Transport Research Advisory Council, 2020). Inductive systems, such as Sweden’s SmartRoad Gotland, use electromagnetic fields to wirelessly charge vehicles via coils buried beneath the road (Schwirzke, Albrecht, & Jepsen, 2022). Overhead catenary systems, like Germany's eHighway project, use overhead wires to charge trucks via a pantograph (Kumar & Yadav, 2023).

Electric roads offer several advantages to commuters and the government for its long-term economic and environmental benefits. This includes dynamic charging that reduces reliance on stationary chargers, improved energy efficiency, and reduced greenhouse gas emissions, making them an essential tool for decarbonization (European Road Transport Research Advisory Council, 2020). They also integrate smart technologies such as traffic and weather sensors (Schwirzke et al., 2022). However, challenges such as high installation costs, maintenance requirements, and the need for standardization hinder widespread adoption. Despite these obstacles, electric roads have the potential to revolutionize transportation by enabling sustainable and efficient EV charging (Kumar & Yadav, 2023).

With innovations such dynamic charging pods and smart infrastructure, electric roads are poised to shape the future of transportation by enhancing energy efficiency, reducing carbon emissions, and increasing convenience for commuters. Despite challenges related to cost and implementation, their potential to facilitate the widespread adoption of electric vehicles (EVs) makes them a promising solution for sustainable mobility.

The integration of dynamic charging pods in electric roads significantly reduces reliance on fossil fuels, thereby lowering carbon emissions. According to the United States Environmental Protection Agency, the transportation sector accounts for approximately 29% of total greenhouse gas emissions in the United States (Nguyen et al., 2024). Electric roads utilize embedded charging sensors that detect the battery levels of passing electric vehicles (Petri & Mikko, 2021), enabling on-the-go charging without the need for frequent stops. These batteries are commonly composed of lithium-ion chemistries such as nickel manganese cobalt (NMC) and lithium iron phosphate (LFP) (Umesh, 2024). While LFP is more affordable, safer, and environmentally friendly due to its lower energy density, NMC offers higher energy density but at a greater cost and environmental impact. Many companies seek a balance between cost, safety, sustainability, and efficiency in battery production. Furthermore, up to one-fifth of battery production waste is recycled into new batteries, reducing resource depletion and minimizing landfill pollution. This sustainable approach shows electric roads as a feasible solution for reducing greenhouse gas emissions and promoting cleaner energy alternatives.

Electric roads reduce the reliance on traditional charging infrastructure such as stationary charging stations. This ensures smooth travel over long distances, eliminating range anxiety and making electric vehicles more practical for widespread use across urban and rural places (Mackenzie, 2024). The wireless charging from electric roads to EVs while driving also removes the burden of carrying large and heavy batteries. Hence, the convenience of electric roads make it a factor of use for individuals alike in the long run.

However, the high installation and maintenance costs of electric roads demonstrate a significant challenge. Sweden, as an example, has approximately 5 million passenger cars, 50,000 heavy trucks and 15600 km of national and European roads, faces financial and logistical hurdles in implementing this technology (Mats, 2019). With the current technologies, electric roads take about 10 million Swedish Krona per kilometer per driving lane to build, which is $1,000,735 USD. It is expected to have a 20-year lifespan. Furthermore, the Swedish economy has struggled with high public debt in the last 2 years and is only projected to recover from early 2025 (European Union, 2024). During the building of electric roads, more lanes have to be closed which can affect an individual's travel, whether in the city or rural area. At the same time with maintenance of electric roads, electric vehicles will have to travel with other vehicles, which does not solve the root cause of the problem of traffic congestion on roads. This delays commuters' travel time, making it inconvenient for them. With the high costs and economic constraints, widespread implementation of electric roads in urban areas may not be viable in the short term, despite their long-term benefits.

Despite that, Sweden had built 1.65 kilometers of electric roads from the airport to the city center of Visby by the end of 2020 (Electreon, n.d.). It has proven to be durable and convenient for travelers, halving their travelling time. This also helps in Sweden's environmental efforts in the long run. Hence, electric roads serve to provide great convenience and have long run sustainability effects. 

In essence, with EVs becoming much more affordable to own, electric roads can become a complement to this (Mats, 2019). The necessity of electric roads depends on a country's finances and the number of vehicles on roads. The building of electric roads is a long-term plan that has benefits to the environment and individuals.

Introduction for Technical Report

Pedestrian traffic lights, essential components of urban safety infrastructure, coordinate pedestrian and vehicular movement through visual and auditory signals. Their development traces back to the mid-20th century, when rapid motorization necessitated standardized traffic control (U.S. Department of Transportation [USDOT], 2010). Research confirms their efficacy: signalized intersections reduce pedestrian-vehicle collisions by up to 50% compared to uncontrolled crossings (Retting et al., 2003). Innovations like countdown timers and adaptive sensors have further enhanced compliance and accessibility, as outlined in the U.S. Federal Highway Administration’s guidelines (Federal Highway Administration [FHWA], 2022). Emerging technologies, such as AI-driven systems that adjust signal timing based on real-time pedestrian density, are now being piloted to address urban mobility challenges (National Association of City Transportation Officials [NACTO], 2023). These advancements align with global efforts to create inclusive transportation networks under the UN Sustainable Development Goals.

1. The use of lidar and sonar to improve road safety in traffic crossroads.

2. I used Google to research more about the uses of lidar and sonar.

11/3/2025

I researched on the different companies to write the report to by using google. Together with zhi guang, we decided on ATS Traffic private limited.

I wrote the benefits and evaluation part for the technical report.

- I leverage on ChatGPT and google to research more about lidar, sonar and AI as well as the impact lidar and sonar brings to individuals and how it helps them with crossing the road safely

For example, I researched that lidar is effective in detecting cars or individuals to ensure safer road conditions because it can scan up to a few hundred metres for vehicles. For the distance of Singapore’s traffic lights, it is more than enough.

- I researched the possible long-term issues our solution might face in a 24-hour sunny and rainy country like Singapore, for example, maintenance issues and system not able to work well.

Lidar is useful to help people cross efficiently, at a faster time. The durability of our solution depends because of the changing weather conditions. For example, the visibility is affected when it rains, affecting the effectiveness of lidar.

With features such as dynamic charging pods and smart infrastructure, electric roads are poised to be the future of transportation by enhancing energy efficiency, reducing carbon emissions and providing convenience to commuters. This facilitates the widespread use of EVs in daily travels.

The use of dynamic charging pods in electric roads reduces the need for fuel, reducing carbon emissions. On average, it was reported by the United States Environmental Protection Agency that the transportation sector contributes to a significant 29 per cent of the total greenhouse gas emissions in the United States (Nguyen et al, 2024). Electric roads contain charging sensors and detect the battery level in EVs (Petri & Mikko, 2021). These batteries are sourced from the most found lithium-ion chemistries in EVs, such as nickel manganese cobalt (NMC) and Lithium Iron Phosphate (LIP) (Tiwari, 2024). LIP is much more affordable, safer and has a lower energy density. NMC has a higher energy density, expensive and not environmentally friendly in comparison to LIP. Many companies desire a cheaper, safer, environmentally friendly and higher energy density material for their batteries. In addition, these batteries can be recycled and up to one-fifth of the production waste is used for the next battery production according to Tiwari (2024). This has two aims - one, the supply of metals used in batteries are scarce and two, avoiding harmful batteries materials to pollute our landfill and play the role as an alternative supply to making batteries. Hence, the use of batteries in electric roads reduces greenhouse gas emissions, providing a more environmentally friendly solution to fuel for the future.

Electric roads reduce the reliance on traditional charging infrastructure such as stationary charging stations. This ensures smooth travel over long distances, eliminating range anxiety and making electric vehicles more practical for widespread use across urban and rural places (Roberts, 2024). The wireless charging from electric roads to EVs while driving also removes the burden of carrying large and heavy batteries. Hence, the convenience of electric roads makes it a factor of use for individuals alike in the long run.

However, the installation costs and maintenance requirements of electric roads are high, which can disrupt daily life. Taking Sweden as an example, it has approximately 5 million passenger cars, 50,000 heavy trucks and 15600 km of national and European roads (Alakula, 2019). Current electric road technologies cost 10 million Swedish Krona per kilometer per driving lane to build and have an estimated 20-year lifespan according to Alakula (2019). This incurred cost is due to the overhead catenary systems in electric roads where overhead wires is used to charge tracks (Kumar & Yadav, 2023). Additionally, Sweden faced financial issues in the past two years, including high public debt though it is expected to recover from early 2025 (European Union, 2024). The construction process requires lane closures, temporarily posing inconvenience to commuters traveling between city and countryside areas. Moreover, EVs must still share roads with conventional vehicles which does not tackle the issue of traffic congestion despite reaping the benefits from electric roads. Given the high costs and managerial problems, rapid expansion of electric roads citywide may not be attainable in the short run.

Despite these challenges, Sweden successfully built a 1.65-kilometer electric road from the airport to the city center of Visby at the end of 2020 (Electreon, n.d.). This project significantly reduces travel time for commuters, further showcasing the convenience and durability electric roads bring. Furthermore, electric roads line up with Sweden’s long-term environmental goals by promoting sustainable transportation. While large-scale implementation presents financial and managerial challenges, targeted electric road projects can still provide meaningful benefits and support long-term sustainability efforts.

In essence, with EVs becoming much more affordable to own, electric roads become a complement to it (Alakula, 2019). The necessity of electric roads could depend on a country's finances and the number of vehicles on roads. The building of electric roads is a long-term plan that has benefits to the environment and individuals.

Taking Sweden as an example, it has an approximate 5 million passenger cars, 50000 heavy trucks and 15600 km of national and European roads(Mats, 2019). With the current electric road technologies, electric roads take about 10 million per kilometer per driving lane to build, in Swedish currency. It can be assumed to have a 20-year lifespan. The Swedish economy has not been doing well with a high public debt in the last 2 years(European Union, 2024). However, the Swedish economy is projected to recover from early 2025. During the building of electric roads, more lanes have to be closed which can affect individual's travel to the city or rural area. With maintenance of electric roads, electric vehicles will have to travel with other vehicles which does not solve the root cause of problem of traffic congestion on roads. These delays commuters' travel time, making it inconvenient for them. With an economy that is recovering and the costs involved in building electric roads, it is almost not possible to build electric roads all around the city.

Despite what was said on top, Sweden had built 1.65 kilometers of electric roads from the airport to the city center of Visby by the end of 2020(Electreon, n.d.). It has proven to be durable and convenient for travelers, halving their travelling time. This also helps in Sweden's environmental efforts.
