1 Language (TL) The language for programming intelligent traffic solutions Intelligent Traffic Systems s Industrial Solutions and Services Your Success is Our Goal

2 Language (TL) The simple answer to complex traffic problems Tailbacks and slow-moving traffic are an everyday sight on our crowded roads. They are a constant challenge to traffic experts all over the world. Action needs to be taken on a variety of fronts: re-routing unavoidable traffic, making traffic fundamentally less harmful to the environment and, above all, making better use of the existing transport network. One main focus of traffic optimization is public urban transport. Much financial and technical effort is expended on reducing the time spent by road and rail vehicles at traffic lights and signals. The quality of traffic flow at signals that are not used by public transport, however, is also being continuously improved with the help of adaptive systems. Writing traffic-actuated programs used to be an extremely timeconsuming and expensive undertaking - a matter for specialists in this field. Language is a language which traffic planners can use to translate complex traffic tasks into a programming code without having to master a difficult programming language. Powerful logic editors assist users in formulating the logical conditions. There are various module libraries included in the program providing solutions that have already been worked out for a whole range of specific traffic problems. All that is necessary is to parameterize the functions, and the results are available to the user for further processing. Thanks to the many standard solutions that have already been formulated and tested, the number of logical conditions that need to be individually specified with Language is cut to a minimum. As a result, the expense of writing specific programs and the time needed for testing them are reduced substantially.

3 PDM Modules for complete solutions Language User library Individual code section PDM library Traffic planners are faced with the task of solving today s traffic problems. Often the pressure of time and complicated programming languages make this more difficult. VISSIM simulation Other library PARA- METERS The library of the PDM phase-oriented method provides ready-made functions with predefined solutions. With the help of Language they can be individually combined and supplemented with additional modules from the user library. The functions of the user library can be customized by each individual user and are then also available in subsequent projects a solution characterized by time savings and ease of use. All the predefined functions are incorporated in each user s individual code section. This includes both the PDM libraries and the user-defined user libraries, which can be linked to each other and added to with the help of Language. S-X variant Standardized PDM sequence S-X is an additive traffic component supplementing the PDM method. As with S-L, the modules are already brought together in S-X. All routine tasks such as checking the outline permission and the minimum green times, the pattern of various flags for the prioritization of public transport, are performed by S-X automatically. Traffic tasks can be put into practice quickly thanks to the combination of parameterization and individually defined interstage conditions. Individual code S-X PDM library PDM Funktionen

4 S-L Simplification through standardization Language Individual code section Flexible yet standardized, universally applicable yet easy to use, limited modification possibilities yet expandable. Self-contradictory? Not at all. VISSIM simulation S-L functions PARA- METERS S-L has already brought the individual modules together in one place. All the user has to do is adapt them to the specific requirements of the respective intersection a simple and trouble-free task thanks to parameterization. Additional features with Language also allow variations from the standard modules for special cases. Simple testing and short processing times with an integrated simulation program Once users have developed the logic, they can test it under real traffic conditions with the VISSIM 3D simulation program. This means that users do not need any direct knowledge of input to the equipment. Not only that, test and processing times can also be significantly reduced. VISSIM* simulates traffic situations under realistic conditions, taking account of all road users * VISSIM is a registered product of PTV AG, Karlsruhe

5 M-X MOTION component for the ler The MOTION system for optimizing traffic signal consists of a optimization method MOTION zentral in the traffic signal computer and an (optional) local traffic-actuated method in the ler. Language Individual code section The two methods can be harmonized with each other with the aid of the M-X component. The use of M-X is therefore always linked with the MOTION zentral method in the traffic signal computer. VISSIM simulation M-X S-L functions PARA- METERS In traffic-actuated in the C800V with PDM, S-X or S-L, the new M-X component is needed in order to calculate a phase-oriented outline plan for local traffic-actuated from the signal timing plan transferred from MOTION zentral. The M-X component for the C800V consists of a library that is integrated with Language into the PDM method with S-X or S-L. It receives its inputs from Control. M-X is not a new local method, but rather an extension to the local methods PDM with S-X and S-L for linking to MOTION zentral.
