International comparative field evaluation of a traffic-responsive signal control strategy in three cities

The recently developed network-wide real-time signal control strategy TUC has been implemented in three traffic networks with quite different traffic and control infrastructure characteristics: Chania, Greece (23 junctions); Southampton, UK (53 junctions); and Munich, Germany (25 junctions), where it has been compared to the respective resident real-time signal control strategies TASS, SCOOT and BALANCE. After a short outline of TUC, the paper describes the three application networks; the application, demonstration and evaluation conditions; as well as the comparative evaluation results. The main conclusions drawn from this high-effort inter-European undertaking is that TUC is an easy-to-implement, inter-operable, low-cost real-time signal control strategy whose performance, after very limited fine-tuning, proved to be better or, at least, similar to the ones achieved by long-standing strategies that were in most cases very well fine-tuned over the years in the specific networks.

An evaluation of a sketching interface for interaction with concatenative sound synthesis.

This paper presents the evaluation of morpheme a sketching interface for the control of sound synthesis. We explain the task that was designed in order to assess the effectiveness of the interface, detect usability issues and gather participants’ responses regarding cognitive, experiential and expressive aspects of the interaction. The evaluation comprises a design task, where partici-pants were asked to design two soundscapes using the morpheme interface for two video footages. Responses were gathered using a series of likert type and open-ended questions. The analysis of the data gathered revealed a number of usability issues, however the performance of morpheme was satisfactory and participants recognised the creative potential of the interface and the synthesis methods for sound design applications.
