Saturation flow is a key measurement of on-street performance. It is an expression of the maximum capacity of a link as predominantly determined by junction characteristics like geometry, layout, turning radii, visibility, as well as vehicle composition. Saturation flows are usually required on each individual lane when modelling signalised intersections or roundabouts. Sat flows were always calculated manually. But today. for the first time, you can get rid of lengthy manual review and calculate it automatically in the matter of seconds with GoodVision.

How does GoodVision calculate saturation flows?

GoodVision Video Insights provides saturation flows calculation as a spreadsheet report for each traffic movement or lane…

Travel efficiency and traffic safety of non-signalized intersections are the main objectives considered in traffic management and control. Most intersections in cities are controlled by signal lights, no matter what level of traffic volume there is. Even if it may increase safety, it obviously decreases the efficiency of the throughput. On the other hand, there are intersections that have no control which leave the decision of safety and efficiency to drivers themselves. This may cause severe safety and congestion issues.

Introduction

Non-signalised intersections have more traffic conflict points than signalised ones. To improve traffic safety and decrease traffic delay, it is…

Almost every company from transportation industry tackles the challenge of efficient traffic data collection. And practically all traffic data suppliers have previous experience with manual traffic counting or tubes on their surveys. Many manual counters claim they can be cost-efficient and can provide traffic volume reports in Excel spreadsheets. But is this enough to satisfy the needs of traffic model calibration in the modern age?

How to do traffic surveys simple and effective

Today it is evident that automated methods of collecting traffic data using artificial intelligence are in the spotlights of transport planners and municipalities. What does this mean for your current operations, how does it look…

At GoodVision Ltd, we are excited to formally announce our partnership with SMDI Consultants, Inc., a transport planning and traffic engineering consultancy firm from Metro Manila, Philippines. Both companies will work together to increase the deployment of smart city technology across the Asia-Pacific.

The city’s ability to quickly respond to emerging needs was extremely limited by existing data collection and evaluation techniques. Majority of the traffic analytics work was performed manually. with limited outputs … until now.

The ultimate intent for urban and transport planning projects is to leverage traffic survey video data into actionable information to make more informed…

A revolutionary functionality available exclusively in GoodVision Video Insights platform. Imagine you could generate a calibrated traffic model within seconds! How much time of manual labour can your team save? Vissim model generation functionality is saving you 95% of your time on traffic skeleton model creation and calibration! In this article, we will train you how to do it step by step on your projects.

Traffic model calibration is a time-consuming task

At GoodVision we are extremely focused on exploring traffic data for the good of the whole transportation industry. …

Deployment of tethered UAV allows us to measure vehicle counts and other important parameters over a continuous and uninterrupted period of time. With the traffic data obtained, we can get a comprehensive overview of the conditions of traffic roadways and junctions. Read the original article HERE.

Volarious specialises in actively tethered system for compact-sized drones and is the trusted choice for public safety and first responders. Volarious tethered system offers an unlimited flight time of 12 hours and beyond, which is highly essential in recording uninterrupted drone footage for the traffic study. …

Year 2020 showed that data security is a crucial topic also in the transport planning industry. Numerous data misuse incidents for third parties own commercial purposes have shown that organisations which collect traffic data for their projects must begin to protect it, for the sake of their own business reputation and continuity.

At GoodVision, we never thought that data privacy measures, which we take as granted and guaranteed in our products from the very beginning, will be such a big point of difference to other methods of working with traffic data in our industry. …

Driving behaviour factors that refer to speed, critical gap or follow-up headway, are the most complex data to obtain in an empirical way. In this article, principal engineer of Vectio Traffic & Transport Planning, describes how to obtain these parameters with GoodVision Video Insights platform.

“Driving behaviour factors that refer to speed, critical gap or follow-up headway, are the most complex data to obtain in an empirical way. GoodVision provides traffic modellers with an interactive platform to obtain the above-mentioned behavioural parameters through a video processing approach. In this way, parameters obtained can be used to calibrate and validate the…
