    ELECTRONIC TRAFFIC SIGNS: REFLECTING UPON ITS TRANSITION
    (Editorial Universitat Politècnica de València, 2016-06-01) Arbaiza Martin, Alberto; Lucas Alba, Antonio; Hernando Mazón, Ana; Blanch Micó, María Teresa
    [EN] In our days we face a fundamental issue concerning road signs. We may display contents in vertical and horizontal format (static signs, variable message signs, road markings), either on a post, a gantry or a dashboard. And we foresee a coming age where the excellent matrix resolution of painted signs will be truly approached by the resolution of full matrix displays. But we also risk a babel context threatening the universal approach encouraged by international catalogues as the 1968 Convention (ECE/TRANS/196, 2007). And the fundamental risk comes from our decisions regarding how the transition from the contents and formats displayed on static message signs to the ones displayed on electronic signs (in gantries or dashboards) should be. Our work explores this issue specifically, considering the transition from Advance Direction Signs (static message signs, class G, 1 in the 1968 Convention) to what could be termed Advance Location Signs (signs concerning the location of variable events with regards to certain landmarks) developed as an adaptation of the G, 1 class to electronic traffic signs.DOI: http://dx.doi.org/10.4995/CIT2016.2016.3217

    ELECTRONIC TRAFFIC SIGNS: THE INTERPLAY BETWEEN HYBRID AND FULL MATRIX E-SIGNS
    (Editorial Universitat Politècnica de València, 2016-06-01) Lucas-Alba, Antonio; Hernando Mazón, Ana; Blanch Micó, María Teresa; Gutiérrez Pérez, Diego; Echeverría Villaspí, José; Landa Tejero-Garcés, Nicolás
    [EN] Road signs constitute a complex and growing communication system where different elements (pictograms, shapes, texts, etc.) are combined following different strategies. In this paper we have confronted drivers with a number of messages (congestion or road works, before, between, after location/s) developed as an adaptation of Advance Location Signs (class G, 1c in the 1968 Convention) to electronic displays. We manipulate two main factors a) the reading strategy (top-down vs. bottom-up) and the type of matrix display (hybrid, dissociating pictogram and text, vs. full matrix), in a repeated measures experimental design. The time taken to answer and the response given (correct, incorrect) was measured for each of the 24 message-blocks. Results show that the organization of the elements displayed is a key determinant for driver comprehension. Further thoughts on the need to understand the interplay between the formats adopted by static vs electronic message signs are provided.
