SAFETY AND ACCESSIBILITY  Architectural intervention is developed in close proximity to transport infra- structure which makes safety one of the main points of attention. Higher level of safety on the ground floor and elevated levels was achieved by creating visible and open plan from the view point of the pedestrian and driver both. Required visually open distances were taken from the calculation of the braking distance of each type of vehicle based on the maximum allowed speed in the zone of development.  It is considered that the maximum speed limit on Passeig de Circumvaŀlació is 25 km/h and maximum speed of the tram and train on the site is 20 km/h.  Braking distance of the train with the speed of 20 km/h in extreme conditions with the lowest braking coefficient could reach 150 meters. This is to understand the minimum length of visibility corridors on the boundaries of which mobility partici- pants are able to see each other. Volume proposal was developed considering men- tioned requirements, which resulted in visually open ground floor planning of the site. In addition to architectural solutions, technical installations are implemented on the main crossings with the train lines to indicate approaching vehicle with the light and sound.  Tram network does not create a hazard for pedestrian mobile group due to the short braking distances on the low speed which are also compatible with braking distances of cars. However to achieve higher level of safety these networks and, par- ticularly, points of their interaction were designed with the use of same principles of high visibility and openness.  To achieve higher safety level for bicyclists and wheelchairs groove fillers could be applied in points of tram and sidewalk intersection. Filler profiles are being used to close up the groove to eliminate a safety hazard for vehicles crossing tracks.  All elevated platforms, passages, slopes, balconies, terraces, exterior staircas- es and galleries are equipped with safety railing.  Developed project is accessible for different mobility groups (pedestrians, cyclists, etc.) as well as
