This paper analyzes a data set that contains reports of road accidents reported by the Municipal government of Bogota city, which occurred between 2016 and 2017, by using descriptive analysis and rule-model algorithms. The main objective is to characterize the road accident data and to highlight the variables that show a significant impact on the type of road accident. The results obtained shows the increase of road accidents by rush hour, from 6:00 to 8:00, one minor group from 12 m to 15:00 and another main group, from 17:00 to 19:00. Also, considering the day of the week, the days with the highest traffic accident frequency were Tuesday, Friday and Saturday. The rules-model obtained allowed to find out that the variables hour, day of week, locality and road geometry show a meaningful effect on the type of traffic accident; the model also allows to infer that the weather conditions does not pose a significant impact on assessing the type of traffic accident. The proposed rule model can be useful to propose accident prevention campaigns and to be incorporated into a traffic control system.

Global use of carbon-based fuels increased by 1.6 % in 2017 and continued increasing in 2018, after managing to maintain emissions flat between 2014–2017. This trend deviates from the emissions trajectory required to fulfill the climate change goals to maintain the earth's temperature below 2-degrees. The transport sector accounts for about a quarter of these emissions but its the sector with the highest dependence on fossil-fuels. In order to reduce emissions, several approaches have been taken, from increasing fuel efficiency to the use of alternative fuels altogether. The most recent trend leans towards electrifiying the transport sector. High penetration of mature renewable energy technologies such as wind and solar photovoltaics as well as energy storage improvements are leading the way. While mass adoption of electric-propulsion systems for boats are still years away, recent pilot projects suggest that electrifying boats for passenger transportation may be not only a sustainable transport solution but its lower operation costs could facilitate its penetration on densely populated coastal and river cities where conventional public transport systems are reaching their full capacity.

Nowadays, vehicles are becoming increasingly connected, both to each other and to the outside world. V2X, i.e., ‘vehicle to everything’, is an umbrella term to refer diverse types of vehicle communications, including vehicle-to-vehicle (V2V), vehicle-to-infrastructure (V2I), vehicle-to-pedestrian (V2P), and vehicle-to-network (V2N) communications. Using all these technologies, cars may talk to other cars, to infrastructure such as parking spaces or traffic lights, to mobile applications used by pedestrians and to cloud-based services via cellular networks. Future intelligent transportation systems may take advantage of these technologies to offer completely new ITS services, not available today. This talk discusses the diverse technologies that support these types of V2X communications, the standards that are being proposed and some ITS services that have been envisioned based on these technologies.
