“…Some of the participants who preferred the route in black commented that the route in blue can be confused with hydrographic features. In the research by Ramos et al (2014a), the authors verified drivers' preference about the color of the route (blue versus black) with a group of drivers with normal color vision. These authors reported that the route in black was preferable because it helped to increase contrast on the map and allowed association with road asphalt.…”

“…Since the process of communicating navigational information can have serious impact on traffic safety, researchers have pointed out the importance of evaluating usability issues by considering individual differences (Burnett 1998;Green et al 1993;Labiale 2001;Liu 2001;Pugliesi, Decanini and Tachibana 2009;Burnett et al 2013b;Lin and Chen 2013;Ramos et al 2014a). Some research works about RGNS map design take the cartographic communication process into account (e.g.…”

In-car Route Guidance and Navigation Systems (RGNS) are used to help drivers navigate. These maps have mainly been designed to accommodate drivers with normal color vision. However, the color perception of people with normal color vision differs from that of people with color vision deficiency. When navigating, understanding certain kinds of information presented by RGNS maps can be a more complex task for colorblind drivers and traffic safety may be impacted negatively. An important aspect related to the graphic design of RGNS maps is the use of a good combination of colors to improve map legibility. Cartographic representations with good legibility aid drivers in comprehending information and making appropriate decisions during driving tasks. This paper evaluates driver preference for RGNS maps designed for drivers with color vision deficiency. A total of 14 subjects participated in an experiment performed in a parked car. Maps were designed to accommodate red-blinds and green-blinds by using a color simulator and principles of perceptual grouping and figure-ground segregation. Based on the results, we conclude that the map grouping symbols representing car and direction arrows in blue segregated from the route in black was more acceptable to drivers compared to other combinations. It is recommended that RGNS should offer a specific graphic design to support drivers with color vision deficiency in navigating.

“…The graphic design of maps of two different scales (1:3,000 and 1:6,000) was based on perceptive grouping and figure-ground segregation as noted by MacEachren (1995), Dent, Torguson and Hodler (2009) and Slocum et al (2009). Additionally, the results of Ramos et al (2014b) relating to driver preference for the color of the route and direction arrow were adopted. The graphic design of the map elements is shown in Table 3.…”

Noise from the information communication process produced by the interfaces of navigation systems has overloaded drivers' cognitive processing systems and increased the probability of traffic accidents. This work evaluates the usability of maps of different scales in a prototype route guidance and navigation system. The maps were designed on basic cartographic communication principles, such as perceptive grouping and figure-ground segregation, as well drivers’ requirements for performing a tactical task. Two different scales were adopted, 1:3,000 and 1:6,000, and the maps implemented in the prototype. A total of 52 subjects (26 males and 26 females) participated in an experiment performed in a driving simulator. The maps describe an urban route composed of 13 simple and complex maneuvers. The drivers’ mental workload was measured in terms of visual demand, navigational error and subjective preference. Results reveal that the usability of maps is influenced by map scale variation, and this is related to maneuver complexity. Also, an association between drivers’ visual demand and gender was found, and this was related to drivers’ spatial ability. More implications are presented and discussed.

Os Sistemas de Navegação e Guia de Rota em Automóvel (SINGRA) vêm sendo cada vez mais utilizados para auxiliar os motoristas na tarefa de navegação. Este trabalho propõe uma avaliação preliminar do desempenho de mapas em diferentes escalas utilizando uma das variáveis que determina a eficácia de SINGRA, o 'erro navegacional'. O intuito é identificar se a escala do mapa influencia na usabilidade destas interfaces ao que se refere à interpretação da direção da manobra. Um total de 52 motoristas (26 homens e 26 mulheres) participou de um experimento simulado que ocorreu em um automóvel estacionado em via urbana. Um conjunto de representações cartográficas, em quatro diferentes escalas (1/1.000, 1/3.000, 1/6.000 e 1/10.000), foi produzido para uma rota composta por treze manobras. As representações foram exibidas em forma de animação no Power Point usando um monitor de sete polegadas. A tarefa dos motoristas foi consultar o mapa e, após ouvir um som de beep, informar, em voz alta, qual a direção da manobra interpretada no mapa. Os resultados revelam uma associação entre o aumento do número de erros e o uso do mapa na escala 1/10.000, tanto em manobras simples quanto complexa. Verificou-se que os mapas apresentam melhor desempenho quando projetados em escalas intermediárias, tais como 1/3.00 e 1/6.000. Constatou-se, também, que os maiores índices de erros são significativamente dependentes da complexidade da manobra, particularmente no caso de rotatórias. Nenhuma associação foi estabelecida entre o número de erros e as características individuais dos motoristas. Concluí-se que a escala do mapa influencia diretamente na usabilidade das interfaces de SINGRA, e que a complexidade da manobra deveria ser considerada no processo de seleção da escala do mapa a fim de se manter a eficácia desses sistemas.
