“…The results of the experiments showed that drivers braked 140 ms sooner or 60 ms later when seeing the expanding (0.4 s ahead) or contracting (0.4 s behind) brake lights at night, respectively, in comparison with the conventional ones. A similar graded deceleration display was designed to replace the rear center high mounted stop lamp in vehicles [33]. Results entailed that the maximum depression of the brake pedal was enhanced by 8% when the graded display was used, and the minimum following distance was increased by 4.6 m (15%), compared with the binary system.…”

Three experiments were conducted to examine the effectiveness of two forward crash warning systems, a flashing brake system and a flashing hazard system, using an advanced driving simulator. In Experiment 1, 20 subjects followed a lead vehicle with a desired time gap and braked when necessary. Results showed that time gap, velocity, and deceleration of the lead vehicle all significantly affected drivers' brake response times. In Experiment 2, six brake response times to a sudden lead vehicle deceleration (0.6 g at 80 km/h) were measured for six time gaps. Results showed that flashing brake system and flashing hazard system reduced drivers' brake response times by 0.14∼0.62 s and 0.03∼0.95 s, respectively, in the various situations tested. The effects of flashing color and illuminated size on drivers' brake response times were examined in Experiment 3. Results showed that flashing amber lamps reduced drivers' brake response times significantly by 0.11 s (10%) on average compared with red lamps. These findings demonstrate the effectiveness of both flashing systems in reducing drivers' brake response times in urgent situations and may warrant further consideration by manufacturers.

Abstract. Modern vehicles are getting smarter and utilize more and more the advantages of Advanced Driver Assistance Systems (ADAS). Deployment of upcoming technologies, such as cooperative systems (V2X), will most likely be the key step towards a significant reduction of accidents across the globe. Some of these systems extend driver's field of vision, so the driver can be forewarned against a wide range of threats. Unlike technology, the human processing capacity has remained almost unchanged over centuries. Therefore, it is necessary to bear in mind that drivers have restricted capabilities to process multiple warnings. In this context, an important question arises: How can be V2X warnings integrated into the Human Machine Interface (HMI) of vehicles, and what warning policy is needed to ensure high usability, acceptance, efficiency and understanding of such a warning interface from the driver's point of view.Using a human centered design approach, two concepts of visual driver-vehicle interface for V2X warnings were developed and evaluated. One of those interfaces was based on a 1-stage warning policy and the second one utilized a dynamic 3-stage warning approach. The research revealed that drivers prefer to have dynamic warnings that correspond with the level of danger to which they are exposed, rather than only one warning displayed in a situation of imminent danger. However, with regards to overall usability score and workload measurements, results showed that the 3-stage system performed worse in comparison with the 1-stage system.

“…The drive simulator study results showed that continuous information presentation in the advisory display could be a good complement to the critical warnings. Stanton [9] conducted a study where a graded deceleration display was implemented, the results entailed that the graded system produced more accurate behavioral responses, fewer collisions and a safer following distance than warning systems. Another example of a graded auditory information system to guide drivers attention by Fagerlönn [10], the results showed that the graded sound information can be useful way to notify the drivers.…”

Abstract-This paper presents a cross-regional study that examined the difference on drivers' preference and behaviors when driving with driver advisory systems between Swedish and Chinese drivers. A drive simulator study was conducted in both countries. Two interfaces were proposed: Design 1 presents directional information; Design 2 combines directional and road user icons. The results showed Swedish drivers perceived a higher acceptance score of the systems than Chinese drivers. Swedish and Chinese drivers expressed different information needs on different regions around the car. When driving with design 2, Swedish and Chinese reduced the number of collisions by 13% and 18% respectively, compared with driving without any system. The brake-to-minimum TTC proved that Swedish and Chinese drivers utilized the systems differently. These findings indicate drivers' preferences and strategies towards advisory systems are highly culturally mediated, and adaptive design for different drivers is highly recommended.Index Terms-Cross-culture, drive advisory system, driving behavior, driver preference. I. INTRODUCTIONAutonomous Driving (AD) cars are developing very fast for its possibility of enhancing traffic efficiency, safety and CO2 emission. During the transition period from total manual driving, to assist automation till full-automated drive, many new human factor problems appear. One of the problems is that drivers may over-rely on the automation systems and it could lead to reduced Situation Awareness (SA), which induce problems in reclaiming control when necessary [1]. Thus, to support SA, we need a system that provide the driver with a foresight on up-coming situations, and helps the driver with decision making on resuming control when necessary, the system should facilitate the interaction between a driver and automated systems [2], [3].Meanwhile, with the rapid development of Advanced Driver Assistance Systems (ADAS) technology, many warning designs have been implemented in vehicles, such as Forward Collision Warning (FCW), Lane Departure Warning (LDW) and so on. Recently, researchers have pointed out that ADAS should focus more on design for SA to provide the driver with attention support, rather than on warnings [4], [5].One of the challenges of ADAS design is to understand Manuscript received September 20, 2014; revised February 23, 2015.

With the technology development, sensor technologies, algorithms for full-automated cars would be ready in the near future, but the drivers might not ready for it. One of the reason is the drivers not have enough confidence to hand over their...
