How Detran PR Used a Holographic Concert to Stop Pedestrians in Their Tracks
Detran PR's 'Holographic Concert on Crosswalk' is a 2017 Brazilian government road-safety campaign that projected a holographic free concert by Curitiba rapper Karol Conká directly onto a pedestrian crossing to reinforce the importance of using marked crosswalks in public urban spaces, according to Detran Pr Gov Br.
Published in September 2017 and created by Tif Comunicação for the Departamento de Trânsito do Paraná — the state traffic authority responsible for road regulation in Paraná — the campaign is also known by its Portuguese title 'Show na Faixa', a phrase that carries the double meaning of 'concert on the crosswalk' and 'concert within the rules'. The activation belongs to the Public Interest and Transport sectors and was distributed through digital media, placing it within a growing category of experiential government communications designed to earn attention rather than simply demand compliance.
In Brazil, where pedestrian safety has historically presented a serious public challenge, Detran PR pursued a strategy of cultural attraction over conventional warnings. The campaign staged its holographic projection on a major Curitiba street, drawing crowds to the crossing itself and making the act of stopping at and using a crosswalk feel like participation in a shared civic and cultural event, according to Detran Df Gov Br. The experience did not end at street level: per Clapboard's editorial documentation, the performance extended onto mobile devices through augmented reality, inviting passers-by to continue engaging with the activation after leaving the scene. With one media asset documented in the campaign record, 'Holographic Concert on Crosswalk' represents a concentrated, single-execution idea built around the power of spectacle to shift pedestrian behaviour in the Paraná state capital.
Detran PR identified a fundamental communications problem facing government road-safety advertising across Brazil. Conventional warning-led campaigns — featuring statistics, cautionary imagery, and authoritative instruction — had become sufficiently familiar to urban audiences that their capacity to interrupt attention had diminished. Tif Comunicação's strategic response was to reframe the crosswalk not as a regulatory boundary but as a destination worth seeking out.
Brazil's road-safety communication environment in 2017 was structurally crowded. Federal Denatran, all state Detrans, municipal traffic authorities, public health agencies, and non-governmental organisations including Maio Amarelo all competed for public attention within overlapping annual communications calendars, according to documentation from Gov Br and Detraneduca Pr Gov Br. The federal 2017 communications calendar, as detailed by detraneduca.pr.gov.br, prescribed month-by-month campaigns covering pedestrians, cyclists, motorcyclists, mobile-phone use, and alcohol alongside driving across the full calendar year. Within that environment, Detran-DF in Brasília and São Paulo's Detran-SP represented adjacent state-level peers pursuing their own road-safety programmes, creating a competitive context in which Detran PR needed a distinctly Paraná-rooted idea to command disproportionate share of attention, according to Campaignsoftheworld.
The choice of Karol Conká was strategically precise. As a rapper with deep roots in Curitiba — the capital city of Paraná — her presence gave the activation authentic local identity rather than the generic authority of an external spokesperson. According to Clapboard's campaign record, the holographic concert was staged on a major Curitiba street, grounding the message in the specific geography where Detran PR holds jurisdiction. By making cultural participation contingent on physically standing at a pedestrian crossing, the campaign converted the compliance act itself into the reward, a structural inversion of traditional government road-safety advertising logic.
Creative director Thiago Biazetto led the 'Holographic Concert on Crosswalk' campaign for Tif Comunicação, with copywriters Rafael Coradine and Isadora Correia, and art directors Waldemar Segundo, Rafael Bortolli, and Johann Stancik contributing to the creative team, according to Clapboard's production documentation. Production was handled by Trunkshot, with audio delivered by Jamute Audio.
The central execution relied on holographic projection technology deployed in an open urban environment — a technically demanding choice that required the production team to engineer a convincing large-scale image in conditions where ambient light, street geometry, and live crowd behaviour could not be controlled. The decision to use holographic display rather than a live performance or a conventional screen distinguished the piece formally: the hologram created a visual phenomenon that justified the gathering itself, making the act of witnessing it feel genuinely unusual. This was not a screen placed beside a crosswalk but an apparition within it, collapsing the distance between spectacle and safety infrastructure.
The augmented reality extension, which carried the Karol Conká performance onto mobile devices after the street event, reflected a considered understanding of how Brazilian urban audiences in 2017 consumed content — moving fluidly between physical experience and smartphone engagement. Rather than treating the street activation and the digital layer as separate assets, Tif Comunicação designed them as a continuous experience, ensuring that participants who had already engaged with the crosswalk physically could re-enter the moment through their devices. Deonilson Roldo is associated with the campaign's broader production context within Clapboard's records. The dual-platform architecture also extended the campaign's earned reach beyond the specific Curitiba street where the holographic concert took place, giving the idea a second life in social sharing and digital news coverage across Brazil.
No verified performance data for 'Holographic Concert on Crosswalk' is publicly available. Detran PR has not published documented reach figures, engagement metrics, or behavioural impact data in publicly accessible records attributable to this specific campaign activation.
Structural analysis, however, supports a clear reading of the campaign's effectiveness as a communications construct. The idea operates at two levels simultaneously: as a public spectacle capable of generating earned media attention across Brazil, and as a behaviour-design mechanism that makes the desired action — stopping at and using a marked crosswalk — inseparable from accessing the reward. This dual function is relatively rare in government road-safety advertising, where the call to action and the gratification are typically sequential rather than unified.
The augmented reality extension demonstrates awareness that a single live street event, however arresting, has a bounded physical audience. By routing the experience onto mobile devices, Tif Comunicação created a mechanism for secondary participation, allowing people who were not present on the Curitiba street to encounter the campaign's creative logic in a different register. The use of Karol Conká — a culturally specific Curitiba figure — added a layer of local credibility that purely instructional campaigns cannot generate.
The Clapboard Score for 'Holographic Concert on Crosswalk' is 61 out of 100. That rating reflects an idea with genuine formal originality and a coherent strategic concept, moderated by the limitations of a single documented media asset and the absence of verifiable impact data that would confirm whether the creative ambition translated into measurable pedestrian behaviour change in Paraná.
Detran PR's 'Holographic Concert on Crosswalk' projected a holographic performance by Curitiba rapper Karol Conká onto a pedestrian crossing in Curitiba, Brazil, in September 2017. Created by Tif Comunicação, the campaign aimed to reinforce pedestrian crosswalk use through cultural spectacle rather than conventional road-safety warnings, with an augmented reality extension for mobile devices.
Tif Comunicação created the campaign for Detran PR. Creative director Thiago Biazetto led the project, with copywriters Rafael Coradine and Isadora Correia and art directors Waldemar Segundo, Rafael Bortolli, and Johann Stancik on the team. Production was handled by Trunkshot, with audio by Jamute Audio, according to Clapboard's campaign documentation.
Detran PR chose holographic spectacle to overcome audience resistance to conventional safety warnings in Brazil. By making the crosswalk the location of a desirable cultural experience — a free Karol Conká concert — the campaign converted the compliance act itself into the reward, a structural inversion of standard government road-safety advertising logic used across Brazilian state Detrans.
Karol Conká is a rapper with roots in Curitiba, the capital of Paraná state in Brazil. Her selection gave the campaign authentic local identity directly tied to Detran PR's geographic jurisdiction. A nationally recognised Curitiba figure, she provided cultural credibility that a generic spokesperson could not, making the activation feel specific to the community it addressed.
The Clapboard Score for 'Holographic Concert on Crosswalk' is 61 out of 100. The score reflects genuine formal originality and strategic coherence in the holographic crosswalk concept, moderated by the campaign's single documented media asset and the absence of publicly verified performance data confirming measurable behavioural impact among pedestrians in Paraná, Brazil.
The campaign extended onto mobile devices through augmented reality after the live Curitiba street activation. This dual-platform design allowed audiences across Brazil who were not physically present at the crosswalk event to engage with the campaign digitally, broadening its reach beyond the single street location and enabling secondary participation through smartphone content.
