Why vs | plus?
Traffic-dependent, standardized and parameterized control programs pursue two goals:
- On the one hand, the aim is to achieve optimal and plausible traffic handling from a traffic engineering point of view. Optimal in this context means low loss times in order to minimize waiting times for all road users. At the same time, a minimum of environmental pollution is achieved. Plausible means creating a flow that is comprehensible to all road users. In essence, a road user should be accounted for within a reasonable time and should not have to wait unnecessarily and without any visible reason.
- On the other hand, one wants to manage the operation of a traffic signal system with as little effort as possible. In cities with a large number of traffic signals, it is not justifiable, especially in the case of traffic-dependent control systems, for reasons of cost and time, that the systems be designed with individual planning and programming. With standardized control systems, the operator knows the sequence of a system based on a few parameter tables. The structure of the parameter tables is the same for all plants. Changes can be done without programming knowledge by changing parameters.
The standard control program described below contains the principles described above. vs | plus is designed in such a way that the operator can execute all currently common control types. It can be used for fully traffic-dependent systems as well as for partially traffic-dependent ones. The entire traffic dependency is defined with parameters. Thus, the whole control sequence can be influenced at any time. With the appropriate software, these changes can be made very easily on site, at the node, or via a central system.
