To ensure smooth communication and collaboration, here are some troubleshooting tips to address common issues:
Check Internet Connection: Verify that you have a stable and reliable internet connection. Use a wired connection when possible, as it tends to be more stable than Wi-Fi. If using Wi-Fi, make sure you have a strong signal.
Update the Browser or App: Ensure that you are using the latest version of the web browser. Developers frequently release updates to address bugs and improve performance.
Clear Browser Cache: Sometimes, cached data can cause conflicts or issues. Clear the browser cache and cookies before joining the meeting.
Test Audio and Video: Before the meeting, check your microphone and camera to ensure they are working correctly. If you are a speaker, you can click on "Start Practice Session" button test to ensure audio and video devices are functioning.
Close Other Applications: Running multiple applications in the background can consume system resources and lead to performance issues. Close unnecessary apps to free up resources for the Dryfta meeting platform.
Restart Your Device: If you encounter persistent issues, try restarting your computer or mobile device. This can help resolve various software-related problems.
Use Supported Browsers: Ensure you are using a browser supported by the meeting platform. Recommended browsers: Chrome, Firefox, Edge, and Brave.
Allow Necessary Permissions: Make sure the Dryfta meeting platform has the required permissions to access your microphone, camera, and other necessary features.
Disable VPN or Firewall: Sometimes, VPNs or firewalls can interfere with the connection to the meeting platform. Temporarily disable them and see if the issue persists.
Switch Devices: If possible, try joining the meeting from a different device to see if the problem is specific to one device.
Reduce Bandwidth Usage: In cases of slow or unstable internet connections, ask participants to disable video or share video selectively to reduce bandwidth consumption.
Update Drivers and Software: Ensure your operating system, audio drivers, and video drivers are up to date. Outdated drivers can cause compatibility issues with the Dryfta meeting platform.
Contact Support: If none of the above steps resolve the issue, reach out to the platform's support team. They can provide personalized assistance and troubleshoot specific problems.
By following these troubleshooting tips, you can tackle many common problems encountered on Dryfta meeting platform and have a more productive and seamless meeting experience.
New method of monitoring CO2-emissions of traffic in AmsterdamView Abstract 01:30 PM - 03:00 PM (Europe/Amsterdam) 2022/02/18 12:30:00 UTC - 2022/02/18 14:00:00 UTC
The city of Amsterdam has big ambitions on the reduction of CO2-emissions. Plans to reduce the emissions of traffic are important to reach these ambitions. So far, Amsterdam made use of data of the national Emissieregistratie database to monitor the local CO2-emissions of traffic. These data are based on a nationale traffic models and can't be used to see the effects of local policies to reduce the emissions of traffic. Therefore, Amsterdam implemented a new method that gives actual data based on local sources. The calculations have been performed by TNO. The method is based on the local traffic model, indices for the traffic volume based on the traffic lights database, data from a huge number of ANPR cameras and national emission factors by TNO. By using this method, it is possible to yearly monitor the realised reduction of CO2-emissions of traffic in Amsterdam. The method can be improved by using information on stagnation factors of traffic. We're looking forward to ideas of the public on this question.
Automated Last-Mile On-Demand Logistics from Multiple DepotsView Abstract Oral presentationSmart Urban Mobility01:30 PM - 03:00 PM (Europe/Amsterdam) 2022/02/18 12:30:00 UTC - 2022/02/18 14:00:00 UTC
Delivery drivers on bikes and vans are a considerable amount of traffic in city centers. Reducing their amount while satisfying residents' needs is a challenge many modern cities face. The new trend of flash-deliveries, where customers order and get their goods within minutes started to contribute to this. In this paper, we investigate same-day delivery operations, specifically with small time windows between ordering and delivery. The problem features the opportunity to pick up goods at multiple local depots, for example, supermarkets within a city, and allows vehicles to perform depot returns prior to being empty, if beneficial. This allows for more agile planning and on average shorter distance to the next depot, resulting in fewer vehicles and traffic. We propose a novel dynamic method for online task assignment and routing, where we aim to deliver orders as fast as possible, minimally within the same day. In each time step (every few seconds or minutes) the following is executed. First, for each order potential pick-up locations are identified and feasible trips, i.e., sequences to pick up goods and deliver orders, are calculated. Then, trips are assigned to vehicles by solving an integer linear program. We simulate one day of service in Amsterdam, compare results to different strategies, and test different scenarios with up to 35 autonomous vehicles, 25 depots, and 10,500 orders. Results underpin the advantages of the proposed method and show its versatility with respect to different situations.
