"Fewer accidents due to 30 km/h in Amsterdam"
Since the introduction of a maximum speed of 30 km/h on a large number of roads within the Amsterdam ring road, the number of traffic accidents on the new 30-km/h roads in the city has decreased.
The number of accidents involving a motor vehicle has decreased by eleven percent, according to a municipal evaluation reported by city broadcaster AT5. The number of accidents between motor vehicles, (electric) cyclists and pedestrians decreased by 15 percent last year.
"We drive thirty to increase road safety and we can now see that it works," responds traffic alderman Melanie van der Horst (D66). "It often takes a while for all road users to get used to it: in Brussels, for example, you saw the speed continue to decrease in the first three years. So I find it encouraging that after one year we already have eleven percent fewer accidents involving motor vehicles on the roads where 30 km/h has been introduced. While we only started enforcing it after six months."
Large-scale
The municipality of Amsterdam reduced the maximum speed on approximately 500 roads and streets from 50 to 30 km/h on 8 December 2023. Many municipalities in the Netherlands have (and are) experimenting with 30 km/h zones, but nowhere on such a large scale as in the capital.
In total, around 4,400 new traffic signs were installed in Amsterdam and 140 traffic lights were reset. In the course of 2024, more than 200 kilometers of markings were adjusted and a number of mobile speed cameras were installed to catch offenders.
The fact that the policy had had results was already apparent in the first interim report in July 2024. The average speed had dropped. Most people found it safer on the streets and called the streetscape quieter and more organised. There was also criticism, especially because scooters and fat bikes often drove faster than cars.
Established
The evaluation that the traffic alderman is now publishing shows that 63 percent of motorists adhered to it or at least did not go faster than 35 km/h. Two in ten went faster than 40.
The evaluation also shows that traffic noise on the 'new' 30 km roads has decreased by an average of 1.5 decibels. Sixty percent of Amsterdam residents are positive or very positive about the lower maximum speed.
Ambulance rides
When it was introduced in December 2023, there were concerns about the response times of the emergency services. However, an analysis of 8,000 fire brigade rides and 50,000 ambulance rides shows that the introduction of 30 km/h had no effect on this.
The average travel time for public transport has increased slightly. A bus ride now takes 40 seconds longer, a tram ride 10 seconds. The number of traffic accidents involving a bus or tram decreased by a quarter.
Trend
"I hope this trend continues: it would be fantastic if we see a further decrease in speed and accidents in the coming years," says alderman Van der Horst. She emphasizes that the municipality will continue to enforce and, together with the judiciary, will examine where new (mobile) speed cameras should be placed.

ADC 1700DD Turntable Restoration - The Speed Controls

It's all about the speed – Quartz Lock Button and Speed Adjustment

On the left side, we've got this cluster of controls and indicators.

So, you select the record speed when you power on the unit (previous post), but here we can lock it in or tweak it. Interesting feature, but not sure what need it’s fulfilling. Based on a quick test, it looks like you can tweak the speed +/- 10%.

This image shows a close-up of the control panel on the ADC turntable. The features visible include:

- A "PRESS" button with "LOCK IN" and "LOCK OUT" options
- A dial/knob with + and - indicators and an orange accent ring
- Speed selection indicators showing "33" and "45" (referring to RPM settings)
- A "QUARTZ LOCK" indicator lit in red
- The word "AUTOMATIC" on the right side
- Part of the vinyl record is visible at the top of the frame

The controls appear to be on a black plastic panel, and the text and indicators are illuminated in red LED lighting. This shows the detailed speed and quartz-lock controls typical of higher-end turntables from this era.

Designed a PWM fan controllers for noisy computers etc. Uses the excellent Microchip TC648 fan speed controller chip at its heart. Just select four resistors and you're good to go. PCB to come...
