Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

node-red-contrib-road-traffic

A Node-RED node that estimates the maximum traffic capacity of a road for various types of vehicles, considering their average speeds and sizes. This node is essential for urban planners, traffic engineers, and smart city developers as it provides critical information for designing efficient transportation systems and mitigating traffic congestion.

Importance

Understanding the maximum traffic capacity of a road is crucial for several reasons:

  1. Infrastructure planning: Urban planners and traffic engineers need accurate estimations of road capacity to design, develop, and maintain an efficient transportation system. This node provides essential insights for making informed decisions about road expansions, new infrastructure projects, and public transportation development.

  2. Traffic congestion mitigation: Traffic congestion leads to increased travel time, air pollution, and fuel consumption. By estimating the maximum capacity of a road, this node can help in identifying areas prone to congestion and implementing strategies to reduce it, such as optimizing traffic light timings, introducing carpool lanes, or promoting alternative transportation modes.

  3. Smart city development: As cities continue to grow and evolve, integrating intelligent transportation systems becomes vital for ensuring efficient and sustainable urban mobility. This node can be an essential component in developing smart city solutions, such as adaptive traffic management systems, real-time traffic monitoring, and dynamic routing algorithms.

  4. Emergency management: In emergency situations, it is crucial to have a clear understanding of a road's capacity to ensure the efficient movement of emergency vehicles and the evacuation of affected populations. This node can help emergency planners to identify bottlenecks and prioritize routes for evacuation or emergency response.

Installation

To install the node, run the following command in your Node-RED user directory (usually ~/.node-red):

npm install node-red-contrib-road-traffic

Usage

This node takes an input message and calculates the maximum traffic capacity for different types of vehicles on a road. The output message's payload contains the maximum traffic capacity for bikes, trucks, cars, cycles, and pedestrians, based on the road's configuration.

The node's configuration properties include:

  • Length: The length of the road in kilometers.
  • Width: The width of the road in meters.
  • One way: A boolean value indicating whether the road is one-way (true) or two-way (false).
  • Bikes: The number of bikes on the road.
  • Trucks: The number of trucks on the road.
  • Cars: The number of cars on the road.
  • Cycles: The number of cycles on the road.
  • Pedestrians: The number of pedestrians on the road.

After configuring the node properties in the Node-RED editor, connect an input node (e.g., an inject node) to the road-traffic node. When an input message is received, the node calculates the maximum traffic capacity for each type of vehicle and sends an output message with a payload containing the results.

Example output message payload:

{
  "maxTrafficCapacity": {
    "bikes": 150,
    "trucks": 45,
    "cars": 200,
    "cycles": 120,
    "pedestrians": 300
  }
}
