Comparable to other major cities worldwide, Berlin aims to reduce traffic emissions. Foremost mechanism for this is to increase the share of bicycle traffic. However, polls show that a lack of safety and fear of accidents keeps people from using their bikes more frequently. Furthermore, it also quite hard from a city planning perspective to get a good overview of location, time, frequency, and kind of hazards in bicycle traffic since official accident statistics only cover crashes but do not provide information on near crashes.In this project, we collect – with a strong focus on data protection and privacy – data on such near crashes to identify when and where bicyclists are especially at risk. We also aim to identify the main routes of bicycle traffic in Berlin. To obtain such data, we have developed the SimRa app that uses GPS information to track routes of bicyclists and the built-in acceleration sensors to pre-categorize near crashes. After their trip, users are asked to annotate and upload the collected data in a fully anonymous way.The collected data offers detailed insights into bicycle traffic in Berlin (and other cities) and hazardous situations to public administrators and other interested entities so that the number of near crashes (and hence also crashes) can be reduced. The data can also be used to optimize traffic flows to make bicycle traffic more attractive. For the evaluation of data, we plan to cooperate with interdisciplinary partners such as city planning, interested citizens, but also the Berlin Senate Department for the Environment, Transport and Climate Protection.

SimbaDroid is an SMB server for Android, allowing you to access the contents of your storage (both internal storage or an external SD card) from your computer via wi-fi. Due to Android limitations, this app requires root (as on all Unixoid operating systems, it is not possible to open a port < 1024 otherwise, and the default SMB port is 445 and Windows doesn't work with anything else). Without root, you either need some sort of SMB client which allows configuring the port used (SimbaDroid uses port 4450 behind the scenes), or some kind of port mapping software to allow Windows to transparently connect to port 4450. Due to JFileServer limitations, only SMBv1 is supported, which isn't ideal for modern Windows, either, but c'est la vie… Since the app is mostly for my private use, at the moment there are no configuration options – shares for the internal storage as well as an external SD card (if one is detected) are set up automatically and are accessible without authentication, so be careful about using this app in public networks. I might add some options for configuring your own custom shares and user authentication eventually, but no guarantees as to if and when. READ/WRITE/MANAGE_EXTERNAL_STORAGE is required for filesystem access.

Protect your privacy and make free mobile phone calls over the internet with Simlar. Your calls are fully encrypted and tap-proof. Simlar is very easy to use. Just select your contact and call them! After installation, all of your contacts who also use Simlar will be listed in the app automatically. Maybe some of your friends already have Simlar. If not, you can invite them easily. Simlar is also available for iPhones. Simlar is based on the established end-to-end encryption protocol ZRTP. No one can listen to your conversation, not even us. During your first call, you need to match a short code with the person you are speaking to. This protects against man-in-the-middle attacks and only needs to be done once per contact. The app development is driven by the open source community. You can find the source code at simlar.org. Simlar is free of charge. All you need is an internet connection. The more stable it is, the better your sound quality. The average “traffic” corresponds to 1 megabyte for a 2-minute call. For more details see simlar.org.
