ISAL 2019 Shows Acceleration of Lighting Tech PDF Print E-mail
Monday, 30 September 2019

Recent ISALs had a strong focus on ADB, mostly looking at systems and ideas for 8, 16, and 32 segments. This year was different: still a predominant focus on ADB, but mainly on high-resolution systems, no longer with a few segments. And besides that, there was heavy concentration on road image projections, visual communication using car lamps, and other suchlike. Terms like "H7" don't occur even once in the proceedings, and "halogen" appears only a few times as a glancing comparison point. ADB technology is gaining traction worldwide; there are even rumours that some form of at least nominal ADB might be approved in the US before too much longer.

As Michael Hamm explained at the DVN US Workshop this year, more than 15 million ADB-equipped cars of about 60 models from more than 10 makers are on the world's roads without any problem. 
A big number, but nowhere near big enough! It is crucially important not only to develop and refine but to sell these technologies.
I see four steps to success:
1. Advertising, educating, and communicating on the benefits of ADB
2. Allowing ADB throughout the world;
3. Democratising ADB so it's available in all car segments;
4. Mandatory ADB in Europe then in the world.
Now the technical constraints that confined us to high/low beam systems have been removed by ADB, we must face and act on the new reality: the high/low-beam binary has never been good enough for the job we ask of it, and people die as a result. That has to stop. Innovation must carry on, of course, but none of it matters without significant sales.

This week, news are focus on ISAL with a summary of the awarded presentations (paper, lecture, poster) then a summary of the best lectures for DVN.
The next ISAL symposium will be held on 13-15 September.

Sincerely yours

DVN President

Investigation of Pedestrian Behavior to 3 Encounter Scenarios with AV
(Tino Singer, TU Darmstadt L-Lab)

The Laboratory of Lighting Technology of the TUD conducted a study consisting of an encounter situation between an AV and a pedestrian in a car park. The tested subjects assumed the role of a pedestrian and were set in a car park scene by using a virtual reality headset.

The AV was equipped with an additional signaling device consisting of three displays in the front of the car. In total nine signals and variations were tested in three different encounter scenarios. The moving behavior of the subjects was recorded, and decision times determined.

The study investigated the three different encounter scenarios in a car park use case. The moving behaviour of the subjects differed in every scenario. In the parking and passing scenarios, the subjects seemed to rely on vehicle dynamics. In the passing scenario, one group of subjects started to cross the road early and another group started the crossing in the deceleration phase of the AV. In this scenario subjects started walking to the destination 0.3 s earlier, when additional signals showed the intention of the vehicle.

When subjects could not directly rely on vehicle dynamics, as in the deparking scenario, additional signals attracted attention. Subjective evaluations show that scenes with symbols provide a better recognition of the intention of the AV and a better safety feeling. Furthermore, uniquely identifiable symbols got top ratings. In future research the investigated scenarios can be extended by adding additional road users. The Influence of other manual driven vehicles, multiple number of signaling interfaces or other pedestrians in a scenario must be investigated.
