Information and communications systems and their services generate a growing number of massive data sets, as the result of their operations. Location-Based Services LBS), Intelligent Transport Systems (ITS), and Internet of Things (IoT) systems and devices, to name just a few, utilise positioning systems, like Global Navigation Satellite Systems (GNSS), thus rendering the majority of massive data generated to be position/location-related. Those may be combined additionally with satellite and the other remote sensing data, and the open-access spatial databases such as Open Street Map and Natural Earth. The ubiquity and amount of spatial data created offer a huge opportunity for information fusion for spatial analytics, spatial statistical learning, spatial modelling, and creation of new spatial knowledge. Methods and case-studies of spatial information fusion using spatio-temporal statistics, spatial analysis, spatio-temporal statistical learning, and spatio-temporal prediction modelling have become of a wide-spread interest. Recognising the importance and prospects of this important research field, CIEES 2021 will arrange a dedicated Special Session on Spatial Information Fusion, and invites interested parties of specialists to submitted their single- and cross-disciplinary contributions to developments in this fantastic, prosperous and developing research field.

Research in the areas of road safety, sustainable transport services, and alternative fuels and fuel cell vehicles has recently seen great progress and made significant contributions to the related science, technology, and application domains.
This special session will report research results in the field of vehicle design and technology, including autonomous vehicles, modelling and simulation transport systems.
The topics of interest include but are not limited to vehicle design and technology, efficiency and ecology of transport engines, automotive electronics, service and diagnostics, motorways and transport, railway technology, alternative fuels for ICE, road safety, auto-technical expertise, autonomous and electric vehicles, fuel cell vehicles, modelling and simulation transport systems, road traffic controllers, etc.
The goal is to present new results that can be successfully applied to numerous engineering applications (e.g., automatic guided vehicles (AGVs), unicycles, cars, trains, ships, aeroplanes, and drones). This special session will provide the opportunity for researchers from academia, industry, and government to present their latest work, share ideas and establish contacts with other researchers in their field.

Digital transformation processes and growing diversity of big data generate challenges for research and development activities. Big Data Infrastructure; Design of methods, models and algorithms for processing big data; creation of methods and models for analysis of big data; design and prototyping methodologies for processing structured, semi-structured and unstructured data specific for big data; designing systems for processing open-source code content oriented to big data, could be part of current research and innovation efforts in the field. Another direction of related topics to digital transformation and big data, could be the integration of big data with input-output documents of digital processes; design of corporate computer solutions for digital transformation; effectiveness and applicability of intelligent business systems for particular areas; design of systems for processing big data working in memory and Hadoop; design of transformation solutions for semi-structured and unstructured data; methods for implementing Computational Linguistics for Digital transformation processes and many other topics related to digital transformation and big data issues.
