Automated Driving</br>in the CityAutomated Driving
in the City

Automated vehicles and intelligent traffic are key components of the urban traffic of the future. Automated vehicles aim to ensure that the driver and passengers enjoy a reliable, safe and comfortable journey in all situations. The interaction between the vehicle and driver, as well as between the vehicle and pedestrians or cyclists at intersections and roundabouts, for example, is of decisive importance to ensure a journey remains safe – and necessitates a solid situational understanding. @CITY is creating the foundations for safe, stress-free, efficient and comfortable driving in the city based on innovative, automated driving functions – which not only bring benefits for the driver, but for all road users.

Sensing and interpreting the environment presents a major challenge in the city. Due to the complexity of urban public roads, much more comprehensive detection systems are necessary than they are in clearly structured environments such as motorways – and must be able to overcome uncertainties and ambiguities. 

Because environmental sensing based exclusively on sensor systems does not currently seem to be a realistic way to achieve an acceptable traffic flow, a priori knowledge in the form of exemplary empirical knowledge and digital maps can and should be used as data sources as well.

To do this, the automated vehicle must be able to precisely pinpoint its location in relation to a highly detailed map, and check it for plausibility before using it.

The information provided by the environmental sensor systems and the data in the digital map must be combined. Only this combination, together with an extensive pool of data on road rules and behaviour, will make anticipatory situational understanding possible – and this is exactly what provides the basis for all automated driving functions for the city. One of the project’s aims is to examine whether components of this data pool can, among other things, be learned by means of machine learning processes based on observations, as well. Using highly effective and dependable algorithms for situational understanding and precise localisation of the vehicle and an optimised configuration of automation functions as a basis, new automated 

driving functions for the city will be developed, implemented as prototypes and evaluated for the very first time.The main focus is being directed at automated driving through complex urban junctions, passing bottlenecks with or without encountering oncoming traffic on urban thoroughfares, and the interaction with vulnerable road users such as pedestrians and cyclists. Different styles of driving behaviour, interfaces, and interactions within the triad formed by the driver, automated vehicle, and outside road users will also be analysed within the project. Another distinguishing feature that makes @CITY unique is that it factors in public transport. Automated city buses will be an inherent feature of inner-city scenarios in future.


Motivation, objectives, project structure

One overall objective of the research project is to establish a shared understanding of automated driving in the city based on a consensus between everyone involved – automobile manufacturers and automotive suppliers. @CITY is pioneering shared, de facto industrial standards. These, in turn, will promote prompt implementation of the results achieved within the project, both in the subsequent product development processes to follow @CITY and among automotive suppliers and automobile manufacturers. Being able to launch sophisticated products at an early stage is a decisive competitive factor for the German automobile industry.

@CITY is being implemented by the partners involved as a pre-competitive collaborative effort. Companies from the automobile and automotive supplier industries, the information technology sector and universities are working together on the project as partners. Within the framework of its ‘New Vehicle and System Technologies’ work programme, the Federal Ministry for Economic Affairs and Energy is lending its support to the initiative, which is divided into two project areas: The foundations for new, automated systems have been being created in @CITY (New technologies, concepts and pilot applications) since September 2017 in the fields of ‘Sensing the

environment and situational understanding’ (subproject SP 1), ‘Digital map and localisation’ (SP 2) and ‘Concepts and pilot applications’ (SP 3). These will allow cross-sectoral insights to be gained that are necessary to put the automated driving functions into practice in the second part of the project, @CITY-AF, which kicked off in July 2018. Building on the main focal points, four additional subprojects have been added with the launch of @CITY-AF: A cross-sectoral subproject (SP4): ‘Human-vehicle interaction’ and three functional subprojects: SP5 ‘Automated driving through urban junctions’, SP6 ‘Automated driving on urban streets’ and SP7, ‘Interaction with vulnerable road users’.
