The Accessible Smart City

Select a sign


LETIsmart can be simply installed in the traffic light network of pedestrian sound crossings integrated inside the pushbutton panel. The user will be able to access the list of nearby crossings and have an acoustic signal he is interested in or activate the booking using the white can.


Bus Stops

Thanks to LETIsmart, at the request of users, the bus stops emit an acoustic signal so that they can be reached easily. In addition, the system lists the lines that pass through that stop.


Public Offices

Public buildings with many counters can become accessible by introducing LETIsmart tags at the entrance and near every office, as well as near the emergency exits.



The bidirectional communication allows the user to receive the audio information from the handle of the white can or minipocket regarding the number of the arriving taxi. Guided on board through the sound of the radio tag mounted inside the vehicle.


Shops, Restaurants, Bar, etc.

Individual businesses, chains or shopping centers can map their presence by installing tags that identify the name and type of business. If activated by the user, they emit an acoustic signal to guide people with visual impairments to the entrance or inside the building.



With LETIsmart it is possible to signal in advance your presence at the bus stop so that the driver stops and pays attention and in case activates the platform for wheelchairs.


Work in progress

The public administration and private individuals who undertake work that hinder normal mobility, can install construction site lamps complete with acoustic signals that indicate the danger to blind or visually impaired people.


Train Station

LETIsmart can be installed in key points of train and bus stations. You can choose the place of interest and have it emitted an acoustic signal to reach it safely and easily.



LETIsmart can make complex environments such as those of the underground network become accessible, signaling turnstiles, ticket offices, stairs and direction of stations.



The entrances of the underpasses can be mapped by LETIsmart tags, which will produce an acoustic signal once identified and activated by the handle of the white cane or by the minipoket.


Thanks to a network of radio tags that are easy to install and distributed in strategic points, the smart city communicates to the most fragile categories: blind, visually impaired and mobility impaired people.

For visually impaired people, a simple modification to the white cane they already use allows them to move independently in the streets, use means of transportation and use public offices. The same system allows the physically disabled person to move easily using the public transport network. It is a simple solution for citizens and administrators.
