Are roads really designed just for cars?
The answer is no. Roads were and are built as basic infrastructure for transport no matter what the mode. However, the standards for dimensions (i.e., number of lanes, widths, etc.) are based on the motor vehicle capacity, and structural standards (i.e., thickness, strength, reinforcement, etc.) are based on the weights they are supposed to carry over their economic lives. The pavement load as it is referred to is usually based on the cumulative heavy vehicle traffic converted in terms of the equivalent standard or single axles or ESA. An ESA is 18,000 pounds or 18 kips in the English system of measurements or 8.2 metric tons in the Metric system.
A typical local road – is it really just for cars or is it also for walking and cycling? Or perhaps animal drawn transport?
A colleague says many of the posts in social media pitting bicycles with cars are already quite OA (overacting). I tend to agree as I read how people generalize roads being car-centric. Roads have been built basically to serve a avenues for transportation. They were improved over time in order to have more efficient ways to travel by land. It didn’t hurt that vehicle technology also developed over time and bicycles somehow became less popular than the cars and motorcycles. The motorcycle itself evolved from bicycles so in a way, it is the evolved and mechanized form of the two-wheeler.
In a perfect world, people would be sharing the road space and it would be equitable among different users. In a perfect world perhaps, it won’t be car-centric as there would probably be better public transport options and transit will be efficient, reliable, comfortable and convenient to use.
The reality, however, is that we do not live in a perfect world and transformations like the ones being pitched on social media are nice but are also not as inclusive and equitable as their advocates claim them to be. I’ve always said and written that you cannot simply change transportation without also implementing changes in land use and housing in particular.
Why do we need wide roads connecting suburbs and urban areas? Why is there sprawl? Why do people live in the periphery of CBDs or the metropolis? It is not just about transport though it seems easier to focus on this. Even transportation in Japan, with Metropolitan Tokyo and its equivalent of NCR plus as a subject, needs to be properly contextualized for land use and transport interaction and development. It seems that even with a comprehensive and efficient railway network, there are still shortcomings here and there. We don’t have such a railway network (yet) so we need to find ways for easing the currently long and painful commutes many people experience on a daily basis. That means continued dependence on road-based transport and trying to implement programs and schemes to improve operations.
