TRES – Mobility system

All services will be stressed, including mobility.

Current problem


hours lost a year

This is equal to a one month of work LOST. Bogota, Mexico City, Sao Pablo, Rio de Janeiro are among cities with worst traffic in the world.


of the air pollution is generated by cars

CO2 emissions reached an all-time high in 2018. A typical passenger vehicle emits about 4.6 metric tons of carbon dioxide per year.


of the world’s children breathe toxic air

WHO estimates that in 2016, 600,000 children died from acute lower respiratory infections caused by polluted air.

Mobility is an essential part of the human experience.

We embrace mobility by designing and engineering a sustainable alternative.

Demographics and Transportation Infrastructure of Bogota

Bogota is one of the biggest cities in LAC with 7.2 million people. Every day, there are approximately 15 million trips. To support this, there is a big and complex operation that includes a wide range of transit services, including informal transportation. Everyday, people travel from dense areas in the outskirts of the city to the city center where most jobs and commercial activities are located. Around 40% of commutes are done with public transit in a combination of services (see Table 1). Studies also show a great correlation between income level and public transit. This reveals that lower income groups are the major user of public transit in Bogota.(Combs 12)

BRT 14%
Feeder 1%
SiTP 24%
Taxi 5%
BiciTaxi 0.2%
Share ride 0.2%
Private Vehicle 11%
Motorcycle 6%
Cable Car 0.1%
Bicycle 4%
Walk 31%




We put a significant effort on understanding of Bogota’s mobility. We looked at mobility patterns, area with higher density, areas with higher job concentration for more service demand, people commuting time, BRT routes, buses, other systems’ routes and informal sub systems. In addition, we wanted to know about motivation and incentives that drive people to choose one option over others. (See Table 1).

Table 2. Current Public Transit Options

TransMilenio Bus rapid system (BRT) that connects metropolitan neighborhoods in a trunk network in Bogotá. BRT runs in a dedicated lane separated from other source of transportation. Passengers pay the entry fee before boarding TransMilenio bus.
Feeders Buses that link peripheral neighborhood with TransMilenio stations. The coverage is very limited and are available in only some TransMilenio stations.
SITP Launched in 2015, the integrated public transport system – SITP – is an operator of public transit in Bogotá. SITP buses are owned by several private companies operated under the government. It covers an extensive area  of the city and it has the highest throughput.

  • Number of buses dispatched in a day
  • Number of buses dispatched during rush hours 
  • Capacity of each vehicle to run through these stations
  • Number of daily passengers that use these stations
  • Entries distribution over the day (rush hours vs. the rest of the day)
  • Peripheral transit options

There was a close relationship between income and transportation distribution. We learned that in low income areas, there is a higher percentage of people that walk and bike because they don’t have the money to pay for current transportation fare. After this findings we formulated the following questions:

How do we design a service that is accessible for everyone?

How do we set it up in ways that helps users save time on their daily commute?

To start, we looked up the current public transit fee, shared bikes, and informal bici-cab service. We got a better understanding of the maximum and minimum charged, therefore, a solid ground to price the service. We decided to start with a similar price as Bici-cab and older buses, because both of them provide last mile services. (see table 4) We were thinking to set the price somewhere between $0.45 and $0.6 USD. Having this numbers, we created a simulation to work with and have the possibility to make future adjustments based on testing and data collection.

Juan 44 years old

He is a doorman at a residential building in the north of Bogota. Getting to work on public transportation takes him 3hrs every day. He rides along the south-north corridor which is  extremely packed during rush hours. He walks for 15 minutes, then takes the BRT for 55  mins and walks for another 20 mins to get to work.

Maria 52 years old

She is a supermarket cashier that works part time during evening shifts 5 days a week. She commutes during off-peak hours which means less traffic but less transportation frequency. She lives next to a BRT station but needs to take informal transportation to get to the supermarket, which is located in an unsafe neighborhood of the city.

Gloria 38 years old

She is a single mom with 2 kids and a cleaner at a market. Her shifts are 7 days a week and with long hours at a market in downtown Bogotá. She leaves to work very early in the morning to avoid traffic. Her commute during weekdays is very chaotic. It involves long walks, and different transportation providers, including informal  and a very packed BRT. Weekends tend to be a better, taking her 90 minutes to commute to work.

Air quality and traffic sensors

Atmospheric levels of carbon dioxide—the most dangerous and prevalent greenhouse gas—are at the highest levels ever recorded.

Our urban ecosystems have become areas of high levels of pollution. The over population of vehicles with combustion engines both gas and diesel make dangerous contributions of carbon dioxide (CO2), a key greenhouse gas that drives global climate change. The need for accurate information about the air we consume is here. We have designed the first transportation system that uses its vehicles to operate as a swarm and collect air related data. Then we process it and deliver. 24/7 – Real time, accurate information of the air we breathe.
