No

4.1 If yes, I request to see the complete strategy, its ambitions and its objectives in PPTX, Word, PDF or picture format.
4.2 I also request a supplementary document that includes all levels of detail on:
(a) Companies and entities involved and the names of the company/entity officers?

(e) I request proof e.g. a certificate from [Council] that confirms that UK, EU and International safety standards for workers and the public have been met.

Following our response above, questions 4.1 and 4.2 are no longer applicable

4.3 If no, I request all documentation, memos, emails and communication on companies and entities you’re in talks with regarding smart roads and smart signage.

There are no specific talks currently underway in this area so we hold no information.

5. Are you planning to rollout or have rolled out LED street lighting?

Yes

5.1 If yes, please answer these questions:

(a) What is the CMS and specification of the software and hardware of the LED street light system?

CMS is only applicable in Exeter where Harvard Technology has been installed.

(b) What type of waveform is the LED? e.g. Square wave?

DCC use LED drivers with constant current, the DC output is flat with no wave. The drivers do not have or need Pulse Width Modulation control as an output to the LEDs, we use LED drivers that are flicker free.

(c) Can you control the Pulse Width Modulation (PWM) of the streetlight system using the CMS?

Following our response to question 5.1 (b) above, this question is no longer applicable

(d) Can you control the PWM of each streetlight that’s connected to the system?

Following our response to question 5.1 (b) above, this question is no longer applicable

(e) What restrictions do you have in place for the control of the PWM?

Following our response to question 5.1 (b) above, this question is no longer applicable

(f) What is the UK, EU and International safety limit (low and high) for the amount of ‘flicker’ (Hz) the Human Body and eyes can be exposed to and for how long?

Devon County Council do not hold this information

(g) I request to see the training manual and safety operation manual for the CMS and the LED streetlight system.

Devon County Council do not hold this information; it is held by Harvard in relation to the CMS.

(h) Who is the company who is or has installed the CMS LED streetlight system?

SSE – Scottish & Southern Energy

(i) What company maintains and repairs the CMS and LED streetlight system?

SSE – Scottish & Southern Energy

(j) What entity and Officer is responsible for the safety standards for the CMS and LED streetlight system?

Harvard and the Maintenance & Installation Teams

(k) I request proof e.g. a certificate from [Council] that confirms that UK, EU and International safety standards for workers and the public have been meet.

All luminaires & CMS systems are CE marked and therefore conform to applicable British Standards and EU Regulations at the time of manufacture.

(l) What is the amount of Blue Light leakage that’s safe for the public and workers during the LED streetlights operation?

Devon County Council do not hold this information

(m) What level of LED streetlight exposure is safe for the public at daytime and night time?

Devon County Council do not hold this information

(n) Is there a legal requirement for diffusers to be fitted to LED streetlights?

No

(o) How have you have addressed the amount of Oxidative Stress on Human and Animal cells that’s produced from LED?

All our LED products are CE marked and therefore conform to applicable British Standards and EU Regulations at the time of manufacture.

5.2 If no, then I request a declaration from [Council] that you will not be installing LED streetlights in the future. If you cannot provide a declaration, I would like the following answered in the future tense:
(a) What is the CMS and specification of the software and hardware of the LED street light system?
(b) What type of waveform is the LED? e.g. Square wave?
(c) Can you control the Pulse Width Modulation (PWM) of the streetlight system using the CMS?
(d) Can you control the PWM of each streetlight that’s connected to the system?

6. Where do you have 3G and 4G systems in public spaces and public roads and what are the makes and models?

The Harvard CMS system uses WIMAC and GSM frequency bands. There are SIM cards operating at 3G within the remote monitoring for traffic systems, on Dambach/Swarco VMS signs and Parking Guidance Systems, and a few Road Weather Stations (Vaisala and Findlay Irvine), situated across the county and other traffic equipment such as traffic counters (C&A, TDC).
