In today’s connected world, the infrastructure choices made by governments have a massive impact on both economic growth and public well-being. While high-speed rail networks offer a modern solution for long-distance travel, I argue that the governments should spend money on improving existing local transport services because they are the most effective way to reduce traffic congestion and minimise environmental damage.
Primary, high-speed rail operates on a macro scale, connecting distant cities, whereas traffic congestion is a macro problem happening inside cities. Improving local buses and trains directly helps the daily routes of most citizens, which removes cars from crowded city streets. On the other hand, high-speed rail cannot solve inner-city traffic jams. For instance, a fast train from Phnom Penh to Sihanoukville does not help an ordinary worker stuck in morning traffic from Chom Chao to Vattanac Tower. However, improving the existing Phnom Penh City Bus system with dedicated bus lanes allows commuters to bypass traffic completely. This better local service encourages daily drivers to switch to public transit, directly clearing up the city’s inner gridlock.
Furthermore, Fast-rail systems only replace occasional long-distance travel, but most air pollution from transport comes from millions of short, daily car trips. Although high-speed only replaces occasional long-distance travel, upgrading local transit cuts millions of daily car trips. Look at the Netherlands, where cities like Amsterdam improved local transport to save the environment. The government replaced old diesel buses with clean electric ones and restricted gas-powered cars in city centers. Because the local buses and trains became clean, cheap, and reliable, most people chose to walk, cycle, or use public transit instead of driving. This quickly cleared up the city’s air and cut pollution, helping nature much more than a single long-distance train line.
Ultimately, even though high-speed rail networks look great for a whole country, improving local buses and trains is what actually stops daily traffic jams and cuts pollution where it matters most.
