NOTES:

  • At all times obey the posted speed limit. This web app is a driver's aid and may/will be incorrect at times.
  • The speedometer reading is updated as the GPS location is updated, which can vary from
  • GPS locations are not available in tunnels and may not be reliable under bridges, in car parks and where there's other obstructions.
  • Speed limit data can be incorrect, out of date, or missing, but you can easily correct this through OpenStreetMap.
  • A verbal alert to slow down occurs when the alert speed selected is exceeded by 2 km/h for four GPS readings.
  • The speed background changes to red with white writing when the alert speed selected is exceeded by 2 km/h.
  • The speed background changes to green when the speed is between 5 km/h under and up to 2km/h over the alert speed. This provides a good visual clue you are travelling near the alert speed.
  • The speed background changes to yellow when on a variable speed limit road.
  • Average speed cameras/Point-To-Point cameras feature. Two empty grey/silver boxes are shown. When travelling through an average speed camera/point-to-point speed camera area a left grey area will show your average speed and the speed limit. The right grey area will show the distance travelled within the zone and the length of the zone. At this stage only single average speed zones are handled.
  • Spurious/inaccurate GPS readings are common on mobile phones and can cause over speed limit warnings
  • When the speed limit is not known, ambiguous or suspect, dashes will be shown.
  • In OpenStreetMaps many suburban streets and regional road do not have a speed entered. The speed limit will show two dashes. It is felt best to provide no speed limit if the speed is not known, rather than provide potentially incorrect information. The driver then makes a decision as to what speed limit applies.
  • With minimal skills anyone can update OpenStreetMaps and those updates are immediately available to provide the speed limit and speed limit alerts.
  • Most existing apps only use the default speed for roads and schools. Speed Limit Alerts includes standard speed limits that don't change, school zones that change twice each day during school terms, speed zones near shops which are restricted during part of the day, for a number of days of the week. If these are missing on roads you drive, you can easily update the information in OpenStreetMaps.
  • School terms and public holidays are included for Australian and New Zealand. For NSW only the Eastern district school terms are used. If you would like to provide school terms and public holidays for your region please contact me.
  • A Night/Day mode button is provided
  • Share your score with family and friends. At the end of each drive you can share a summary of your score, start time, end time, elapsed time, distance travelled and a list of alert locations. Your score starts at 100 and is reduced by one for each alert you hear for exceeding the speed limit. The Share Score feature uses the built-in share feature of the mobile phone. A title line, body for the message and URL for this web page is shared. What works and doesn't work may differ between iPhones and Android based phones.
  • If you see an incorrect speed limit sign, or the speed limit isn't display, click on Speed Sign Issue. The Share Score report also contains the list of reported issues so you can make changes on OpenStreetMaps.
  • The loog provides a full log of your drive. Using the log and the issues you report using the Speed Sign Issue button, you can use the data to make changes to OpenStreetMaps. This means next time you drive on the same road, you'll have fixed the speed limit issue for yourself.
  • On Android set the mobile to answer calls by showing a pop-rather than the full screen to prevent Speed Limit Alerts going into the background and pausing.
  • When using nagivation aids like Google Maps and Apple Maps, start your navigation and then open Speed and Camera Alerts. Google Maps and Apple Maps will continue providing navigations instructions and Speed and Camera Alerts, will provide alerts, speed and speed limit information.
  • Should you switch to another application, Speed and Camera Alerts will stop running until you return Speed and Cameras Alerts to the foreground. Speed and Cameras Alerts, like any web app, when run in the background is suspended and won't record any information.
  • Speed and Camera Alerts was initially designed for Australia and New Zealand. For other countries and regions only Speed and speed limit information and alerts is available by default. If camera data, school terms and public holidays are provided for a country/region, these will also be available. I am only one person so it's not possible to collate all the data required for all countries/regions.


Limitations

  • If you change countries/regions whilst driving, you must fully close and restart the web app. The country/region is detected on start up and does not currently get updated during a drive or overnight. The country determines whether km/h or mph is used.. The OSM data by default Left or right hand driving is handled by the OpenStreetMaps data.
  • OpenStreetMaps is a global community effort. Sometimes data is missing, inaccurate, out-of-date, are just simply wrong. The beauty of OpenStreetMaps is anyone can sign up and edit the data. Any edit you make is available effective immediately on Speed and Camera Alerts.
  • Speed and Camera Alerts uses the publicly available infrastructure of OpenStreetMaps and at times it can become unreliable. However, I've designed Speed and Camera Alerts to use the latest data when available and also store a local copy with the latest data. As you drive you build a store of the roads you've driven on which will be updated each time you drive on them. This is called the cache. You can export/import and clear the cache. People can also share their cache with others so you can immediately have coverage even without internet coverage. If all else fails, you can select a speed setting.
  • When sharing the score via an email, on Android the subject shows the score, whereas on the iPhone the subject is blank. This a limitation of the iPhone software.
  • GPS drift on mobile phones can result in the wrong road being selected. GPS drift is where the location provided by the GPS isn't price enough. For example the GPS is closer to a service road than the main road. In this case false alerts can be issued as the speed is picked up from the service road. A great deal of work has been done to minimise the effects of drift, but I'm not a miracle worker. At times you will get a false alert. So always obey the speed limit signs.


Reporting cameras
Personally I don't feel there's much need to report police and mobile speed cameras and speed camera trailers, because if you're obeying the speed limit, which is easy now with Speed and Camera Alerts, they shouldn't be much of a risk. However since people like to report the cameras, the feature has been provided. Also it's a extra safeguard in case the OpenStreetMaps data is lacking in a specific location. The buttons provided enable people to report police or police cars using radar/lidar, mobile speed cameras, speed camera trailers, and mobile phone seatbelt cameras (those on the tall booms). The buttons should not be used to report the location of police performing other tasks or moving police vehicles. This web app is useful for speed related issues, mobile phone seatbelt cameras and where's there's an increased risk, such as red light cameras, where a simple mistake can be costly.

Each day reported cameras start fresh for the day.

If you drive towards a mobile camera, police camera, mobile phone and seatbelt camera, or a fixed phone and seatbelt camera an alert will be spoken as to the type of camera.

Known fixed phone and seatbelt cameras are automatically included in the list of cameras. An update recently includes all known portable mobile phone and seatbelt cameras, speed camera trailers, as a zone alert. This enables people to become aware of the risks of the portable cameras, which in some cases can result in huge fines.

Show Score
A fun way to help people improve their driving skill. At the end of each drive you can show and share your score. You start with 100 points and lose a point every time you're told to slow down. Share with family and friends on social media and see how your compare with others. Aim to get the perfect score more often which shows you're complying with the road rules. Also included in the score details are GPS and speed details for the alerts. You can copy the GPS location into Google Maps and see where you've exceeded the speed limit. None of the score or alert information leaves your phone unless you choose to share the information with others.

Speed Sign Issue
The Speed Sign Issue button enables you to report an speed limit sign issue at the current location. This could be missing speed limit data, incorrect speed limit data, missing time-of-day speed limit data around schools and shops. By clicking the Speed Sign Issue button the location is recorded in the Share Score report and can be used to update OpenStreetMaps. Combined with the log you have everything you need to improve Speed and Camera Alerts for your needs.

Email issue
The Email Issue button is to email an issue such as a new fixed speed camera, that you would like to share with me. I believe almost anyone can update OpenStreetMaps, but features outside of OpenStreetMap such as new fixed speed cameras, need to be updated by me. If you think something is worthwhile to report, please report the issue.

Privacy and your information
Any location technology you use on your mobile phone, including the cell phone towers, Bluetooth, Wi-Fi and GPS can be used by the hardware and software providers to provide that data to other companies and government agencies. I can't do anything about that data.

However, my Speed and Camera Alerts web app does not collect any data you do not personally share. For example when you submit a mobile phone camera only the date/time, location, type of camera and IP address (used to match data for quality assurance) is collected and used by the system. If you send me an issue report I'll act upon the issue, contact you and then delete your information. I have no desire to collect anyone's information. Having said that, the shared hosting service I use, does record all interactions on my websites and that information if used, may potentially identify an individual device, but not the individual.

Essentially it is not my aim or desire to collect, store, share or transmit people's data. My only desire is to provide a tool that is useful to myself, friends and others who wish to use it. Advertising on the web pages is used to help compensate me for my efforts.


Credits

Speed and Camera Alerts web app uses OpenStreetMaps (https://www.openstreetmap.org/copyright), Overpass and Nominatim.
I encourage anyone using this web app, if they notice a speed limit missing or in error, to edit the data in OpenStreetMaps. Around 90% of roads have a single speed limit and the data for these roads is very easy add or change. It is very easy to learn the skills required on OpenStreetMap to make nearly all the changes required to provide you with the current speed limit for the roads you drive on.

Speed camera locations is based on data from state and country government services and augmented by considerable research.
