Transport automation will significantly affect people’s lives, merchandise transport and other transport-related sectors   . It is precise in this context of progressive automation that the development of new technologies applied to transport becomes an aspect vital to the competitiveness of companies engaged in mobility, affecting their future positions in the economic, environmental and social areas. For all these reasons, road transport automation currently represents a global priority concern, reflected in the work programs of the European Commission   concerned with research into land transport. In more concise terms, the benefits expected from transport automation are described below:
・ Safety: The reduction of accidents associated to human error.
・ Increased transport efficiency (energy consumption, etc.).
・ Comfort for users and professionals, increasing resource availability for other tasks.
・ Social inclusion, making mobility for everybody possible for longer periods.
・ Accessibility in reaching city centres and other areas of difficult access.
With regard to increased efficiency, vehicle automation offers great opportunities for those companies, to whom mobility is critical to operating costs, affecting the entire value chain  . In this sense, not only private cars will benefit from the advantages of automation; passenger transport companies, logistics, and other sectors of the urban setting will also benefit from the boon that automated driving offers.
Specifically, AutoMOST, which main information is shown in Figure 1 (see more detailed Figure 2 & Figure 3 too), will enable the implementation of shared (dual mode) control systems for future automated vehicles that will allow for the more efficient and flexible operation of services in a context of interconnected smart infrastructures.

AutoMOST approaches the research and development of enabling elements holistically, simultaneously affecting the value chain to ensure high industrial impact and global leadership positioning for the companies comprising the consortium. In doing this, it departs from the application of existing functions, such as the following driving assistance systems  : Adaptive Cruise Control (ACC), Lane Keeping System (LKS), pedestrian detection, smart infrastructures... to facilitate highly efficient operating systems for companies and infrastructures providing mobility, while demonstrating operational cost reductions in specific applications.
Figure 4 shows the advantage of project opportunity, according to a recent study by Morgan Stanley (Company Data, Morgan Stanley Research), which is consistent with ERTRAC vision, especially in applications focused on the urban environment  .

The general purpose of AutoMOST is to develop technologies enabling vehicle automation for application to urban and industrial transport with a view to significantly increasing efficiency, safety and sustainability  .
2.1. Scientific and Technological Objectives
Following are the scientific and technological project objectives arising from the aforesaid general purpose.
・ To design and implement a control architecture for automated vehicles of different types (passenger car/large bus), defining each of the blocks in this architecture in a modular way so as to be easily interchangeable, and implementing the different advances in keeping with the new electric/electronic vehicle architectures (in line with standards).
・ To implement on-board perception systems for automated vehicles in urban and inter-urban settings, as well as to design controllers for steering (lateral driving) and for pedals (longitudinal driving) that can be used individually and jointly.
・ To implement a global and local route generator for real-time vehicle path definition and optimum velocity profile definition based on the data supplied by 3D maps, communication systems, vehicle models and propulsion system status.
・ To implement a communications system between vehicles and infrastructures (V2I) that will enable optimizing previously defined profiles and routes, along with the development of infrastructure systems (control centre) for operating the system safely, in tandem with traffic management.
2.2. Technical Approach and Structure of Activities
Over the last few years, automated vehicles have been accepted by a great proportion of car manufacturers  . The benefits this can bring to transport, along with infrastructure, social, safety  , emission and other advantages, place us squarely on the path to one of the ground-breaking technologies of the 21st century.
2.2.1. Technical Approach
AutoMOST focuses on the use of many of the functions already existing for automated vehicles up to the present, avoiding additional efforts with regard to systems already tested and validated. AutoMOST seeks to go beyond by developing technologies that enable automated “dual mode” driving under real traffic conditions, interacting safely with the dynamic urban environment and with expert drivers to validate interaction between different automation levels  and thus allow for safe, efficient deployment.
The control architecture to be developed in AutoMOST enables implementation of a modular solution for automated vehicles considering safe behavior in different scenarios, particularly in settings structured at urban speeds (ports, urban and inter-urban areas). Hence, the AutoMOST work methodology is based on the architecture shown in Figure 5 which is depicted below.
Figure 5. General abstract of automated vehicle control architecture.
This architecture is based on the different advances developed by different international research groups and centres: California PATH, Karlsruhe Institute of Technology (KIT), the University of Parma (and Vislab), Carnegie Mellon University (CMU), Darpa Grand Challenge, Hanyang University, INRIA, etc.
Architectural modularity is a key aspect of the AutoMOST project, since it ensures the adaptability of the system to different computational environments. On another side, the greatest contribution of this architecture is reflected in the dynamic route generator, which takes the conditions of vehicle, infrastructure and obstacles into consideration in defining the route to follow and alternative routes in real time: This block represents the intelligence of the vehicle, which will allow it to negotiate different environments.
To date, most of the contributions to autonomous driving have focused on the modules for perception, communication and activity. AutoMOST focuses on the development of the modules shown in the following figure, with particular emphasis on the decision-making module, in which on-board intelligence will enable more solid control of the different situations in urban environments. The figure below shows the distribution of contributions from each partner, as per the principal on-board vehicle modules. Figure 2 and Figure 3 shows the distribution of contributions from each partner, as per the principal on-board vehicle modules.
2.2.2. Structure of Activities
Figure 6 describes the principal technical activities to be conducted in the AutoMOST project in accordance with the following activity diagram.

Figure 6. AutoMOST activity diagram.
・ Activity 3: Conduct of the tasks related to on-board intelligence: design of direction controllers (lateral driving) and pedal controllers (longitudinal driving), and the implementation of a global route and local path generator for the real-time definition of routes to follow, using the data from the positioning and obstacle detection system and the definition of optimum velocity profiles based on data from 3D maps, communication systems, vehicle models and propulsion system status as reference.
・ Activity 4: Implementation of a communications system between the vehicles and the infrastructure (V2I) making it possible to optimize previously defined profiles and routes and warn about some emergency situations.
・ Activity 5: Development of infrastructure systems with a central control center for safely operating the automated vehicle system while managing overall city traffic.
・ Activity 6: Implementation and testing of the subsystems developed in activities A2-A5 in all use cases: Automated electric bus for passenger transport at the Málaga port and smart vehicles for infrastructure maintenance.
The diagram in Figure 7 shows the timeline for the technical activities projected, including the most relevant milestones.
The AutoMOST project is resolved to develop technologies enabling vehicle automation for application to urban transport and thoroughfare status monitoring, with a view to significantly increasing efficiency, safety and sustainability. It is for this reason that a high degree of innovation may be expected as a result of
Figure 7. AutoMOST project gantt diagram.
the project. The following are therefore outstanding among other innovations:
・ Integration of the results from different disciplines to automate an electric bus for transport in the urban setting, as well as a vehicle for thoroughfare infrastructure monitoring.
・ Development to implement the blocks of a modular control architecture for autonomous vehicles.
・ Development to implement a multi-sensor perception solution for autonomous vehicle positioning in urban settings.
・ Development of an on-board system operating in real time to generate curve parameters based on data from on-board perception systems.
・ Development of a global route generator based on the data from on-board communication systems and sensors.
・ Development of a dual system that will enable drivers to choose the type of activators to use in driving, as it is carried out for platoons   .
The challenges identified in research on both navigation and driverless vehicle control systems in dynamic urban environments are at a relatively low stage of maturity. Hence, up to now, many of the capabilities for avoiding accidents with potential obstacles and facilitating cooperative manoeuvring between automated vehicles have been limited by the scope of development projects, which usually resolve very specific scenarios under highly controlled circumstances  , making deployment hard in complex environments, where multiple circumstances exist. This makes a decided effort for implementation in real urban settings necessary  -  .
It may thus be concluded that AutoMOST focuses on the use of many of the functions already existing for automated vehicles up to the present, avoiding additional efforts with regard to systems already tested and validated. AutoMOST, however, seeks to go beyond by developing technologies that enable automated and “dual mode” driving under real traffic conditions, interacting safely with the dynamic urban environment and with expert drivers to validate interaction between different automation levels and thus allow for safe and efficient deployment.
