Vehicle trajectory prediction is an important decision-making and planning basis for autonomous driving systems that enables them to drive safely and efficiently. To accurately predict vehicle trajectories, the complex representations and dynamic interactions among the elements in a traffic scene are abstracted and modelled. This paper presents vehicle–road relationships net, a deep learning network that extracts features from vehicle–road relationships and models the effects of traffic environments on vehicles. The introduction of geographic highway information and the calculation of spatiotemporal distances with a reference not only unify heterogeneous vehicle–road relationship representations into a time series vector but also reduce the requirement for sensing transient changes in the surrounding area. A hierarchical long short-term memory network extracts environmental features from two perspectives—social interactions and road constraints—and predicts the future trajectories of vehicles by their manoeuvre categories. Accordingly, vehicle–road relationships net fully exploits the contributions of historical trajectories and integrates the effects of road constraints to achieve performance that is comparable to or better than that of state-of-the-art methods on the next-generation simulation dataset.

The paper presents a human-machine design approach to the artistic and metaphoric representation of the traditional weaving scene of Yunjin brocade as interactive Moiré patterns accompanied by Nanjing Baiju. We extract the basic elements of Moiré patterns and systematically recompose them to mimic the weaving process. Then, we wrote an algorithm to generate eye-shaped Moiré patterns responding dynamically to the unique sounds weavers make while weaving, symbolizing the long and tiring gaze of warp and weft, and eye contacts between weavers. Finally, we develop a sonic interactive installation with the rhythmic machine sound and Nanjing Baiju Sweating Weaving Room, visualizing the hard labor and harmonious work hidden behind the glamourous brocade.
