ASAPP ONE - Intelligent Shuttle Fleet Connecting A Split Container Storage Area For Intermodal Operation Improve
Overview
Background & policy context:
The ASAPP ONE project is funded by the European Commission under the 5th Framework Programme GROWTH, DG TREN and attached to the Key Action 'Land Transport and Marine Technologies'.
The high level of activity in ports, including complex organisational and logistical processes and movements, combined with lack of space, can often lead to chaotic and even dangerous scenes. The ASAPP project and the new complementary initiative ASAPP ONE, running until August 2003, aim to drastically reduce loading and unloading times of ships in ports as well as the evacuation of containers from ports to inland transportation networks.
Partners have established the definition of a dedicated link wherein hinterland depots would receive freight from road or rail vehicles and then transfer it via an automated shuttle to seaport depots and then to ship loading berths, and vice versa.
Objectives:
The ASAPP ONE project is aimed specifically at tackling the challenging new configuration of the proposed shuttles and at creating an efficient system for getting the right containers to the right location at the right time.
This project proposes the solution to the growth impossibility of the second rank container terminal due to space and traffic constraints. The system is a dedicated rail track (new or existing) connecting the port yard to a peripheral inland depot, operated by automated shuttles and managed optimising the line exploitation driving the shuttles from the front end to the loading bays also.
The vehicle ASAPP One will run as autonomous shuttle or in a 'convoy mode' without any mechanical link between the shuttle train. The system will eliminate the road traffic problems in the urban areas surrounding the ports (> 2000 trucks/ day for a second rank port) in favour of the middle range railway transport.
The consortium is formed by container handling machinery industrial companies, engineering houses, research institutes and intermodal business users. A validation field test will be done.
Methodology:
The work program for ASAPP ONE consists of developing a transfer system with a new design of motorised wagon based on some ASAPP (automated shuttle for augmented port performances) solutions, but having innovative and enhanced performances, especially in on-board and general control systems, devoted to operation conditions and able to maximise the path use (the distance being 5 to 50 km) utilising existing or new rail tracks. The performance of the shuttle must be the following:
- able to run as a single shuttle to the 'max allowable speed' (the maximum speed vs. the dynamic distance toward the preceding shuttle);
- able to run in 'virtual convoy mode' with a new concept proximity control able to provide a 1.5 m gap without mechanical links;
- able to join a convoy or move from it;
- able to run on train rail tracks in addition to the ASAPP features (solid rubber wheels);
- able to transport up to 6 TEUs (3x2 high).
The structure of the project and the project work follow the traditional procedure and starts with functional specification (logistic requirements and general architecture) followed by the development of each subsystem:
- line management system (tested in performances with a virtual split terminal simulator);
- shuttle 'improved version one' design, construction and set-up with twin wheels for flat surfaces and rail tracks;
- shuttle onboard control system with shuttle-to-shuttle proximity adaptative control system;
- local traffic control and field sensor system for front end and swap point control. It comes up after integration and final validation tests with concrete recommendations for the exploitation of the results.
