The
VS-PLUS Control Philosophy |
- Optimized control transparent to road user
- Short loss times resulting in
low environmental impact
- Green in an reasonable amount
of time
- Road user should not be kept
waiting for no apparent reason
- Operation of signal control
with:
- minimum of cost and manpower
- highest possible quality of
control
- Control types
- fully traffic actuated control
- semi-coordinated control
- fixed time control

VS-PLUS
Version 5.0 |
- Fully traffic actuated control
- Traffic control designed for
transit signal priority (TSP)
- Free phase combination and
sequence (important for priority driven control)
- Unlimited number of phases
- Highly flexible transit
priority based on
- route and trip identification
- lateness or user defined
priority code
- Proven control package, more
than 1,000 installations
- Full integration with design
and test tools

VS-PLUS
5.0 Transit Signal Priority Treatment |
- Multiple levels of priority
treatment
- Transit vehicle’s
lateness (in minutes) or user defined priority code
- Competing transit priority
calls
- Special treatment of trailing
trains/buses (bunching)
- VDV communication protocol
- Multiple calling points
- 2 advance calls
- Confirmation
- Checkout
