The hidden cost of moving

Time, money, safety and health are currencies of mobility. Mobility is never free, even when the ticket is.

The Same same but different series explores mobility and spatial justice in Tallinn and Bangkok and is part of SEIs research program on sustainable transport. This chapter examines mobility-related safety, environmental impact and health risks in both cities.

Beyond fares and fuel, the hidden cost of moving includes exposure to traffic risks, polluted air, noise, long commute times and the physical strain of navigating car-dominated environments. These costs are unevenly distributed depending on how, when and where people move.

We asked:

  • How long does a daily commute take?
  • How congested are the roads?
  • Who is prioritized and who must wait or detour?
  • How is road safety addressed across different users?

Tallinn: free transit, costly conditions

Free public transport provides mobility access for Tallinn residents, yet route planning can be inefficient and commutes long. Road space is dominated by cars and becomes heavily congested during rush hours. Pedestrians and cyclists rarely receive priority and are frequently required to wait, detour or navigate uncomfortable crossings.

Car-oriented planning reduces safety and comfort for pedestrians and cyclists. Pedestrians are often squeezed between fast traffic and greenery, sometimes left standing in narrow refuge islands.

Weather adds another layer of cost.

In rain, pedestrians stand in splash zones and puddles while cars speed past, soaking clothing and belongings. These puddles often contain petrol residues, oils and bacteria, posing health risks to people and pets.

Winter imposes a seasonal mobility “tax”. Darkness, ice and snow create hazards, especially for elderly people and those using mobility aids, who must navigate slippery sidewalks, cold winds and reduced visibility with every step.

Conflicts between cars, e-mobility users, cyclists and pedestrians remain a constant feature – reflecting a system still transitioning from vehicle dominance toward safer and more equitable movement.

Bangkok: comfort versus exposure

In Bangkok, air pollution, heat, rain and congestion shape everyday choices. During monsoon downpours, the city can grind to a halt for several hours. During the hot season, temperatures often exceed 40°C.

Cars remain the preferred option despite delays, their comfortable interiors offering shelter from heat and storms. Motorbikes provide speed and efficiency but expose riders to pollution, heat and elevated crash risk.

Outdoor workers – motorbike taxi drivers, street vendors and delivery workers – face these conditions year-round while keeping the city moving.

From icy sidewalks to toxic air and hours lost in congestion, the true cost of mobility is paid in time, health and safety – and these costs are not shared equally.
