Counting and storing pulses from detector #202

Open FredrikOtterdahl opened 2 weeks ago

FredrikOtterdahl commented 2 weeks ago

City of Gothenburg has a suggested improvment for the RSMP due to be able to count vehicles that pass inductive loops in existing infrastructure.

Proposal for requirements specification.

Detector pulse = Pulse from inductive loops when vehicle passes.

  1. Control devices in road traffic signal systems must have a configurable function for detector pulse for all detectors.
  2. Detector pulse in control devices in road traffic signal systems must be able to be connected to any detector connected.
  3. Detector pulse in control device for road traffic signal system must be with storage of number of pulses with a resolution of 5 minutes.
  4. Detector pulse in control device for road traffic signal system must be with storage of number of pulses with at least one week storage.
  5. Detector pulse in control device for road traffic signal system must be with reading of values via:
  1. Control devices in road traffic signal systems must be able to read out the detector pulse via display, web interface and communication interface.
  2. Control devices in road traffic signal systems must be able to change or reprogram detector pulse via control panel, RS232C and web interface.

Thank you for the input.

However, I wonder if these requirements fits in the RSMP specification. I think these requirements handles traffic counting in general and does not necessarily only applies to RSMP.

At the Swedish Transport Administration, these types of requirements are defined in the requirement document for traffic signals known as Vägtrafiksignalsystem 3.0 (TRVINFRA-00217). You can read it here.

But perhaps requirement 1 and 2 could possibly be incorporated in the RSMP specification. I'll think about that...

Detector pulse = Pulse from inductive loops when vehicle passes.

1. Control devices in road traffic signal systems must have a configurable function for detector pulse for all detectors.

Very similar to requirement K27608 in TRVINFRA-00217

2. Detector pulse in control devices in road traffic signal systems must be able to be connected to any detector connected.

Very similar to requirement K27609 in TRVINFRA-00217

3. Detector pulse in control device for road traffic signal system must be with storage of number of pulses with a resolution of 5 minutes.
4. Detector pulse in control device for road traffic signal system must be with storage of number of pulses with at least one week storage.

Very similar to requirement K27610 in TRVINFRA-00217. But in RSMP, any resolution can be chosen. Storage of traffic data is not applicable to RSMP since all traffic data is transmitted continuously.

5. Detector pulse in control device for road traffic signal system must be with reading of values via:

* a.  RS232 interface (terminal program/modem)
* b.  web interface
* c.  API

Very similar to requirement K27611 in TRVINFRA-00217
