viasegura 0.0.1.34

A python package to interact with Inter-American Development Bank machine learning models to automatic label elements for iRAP certification

VIAsegura

Project Description

VIAsegura is an API that helps to use artificial intelligence models developed by the Inter-American Development Bank to automatically tag items on the streets. The tags it places are some of those needed to implement the iRAP road safety methodology.

To use it you must contact the Inter-American Development Bank to obtain the credentials that give access to the models with which the API works.

These models require images with the specifications of the iRAP projects. This means that they have been taken every 20 meters along the entire path to be analyzed. In addition, some of the models require images to be taken from the front and others from the side of the car. The models yield 1 result for each model for groups of 5 images or less.

So far, 15 models compatible with the iRAP labeling specifications have been developed and are specified in the table below.

Model Name	Description	Type of Image	Classes
delineation	Adequacy of road lines	Frontal	2
street lighting	Presence of street lighting	Frontal	2
carriageway	Carriageway label for section	Frontal	2
service road	Presence of a service road	Frontal	2
road condition	Condition of the road surface	Frontal	3
skid resistance	Skidding resistance	Frontal	3
upgrade cost	Influence surroundings on cost of major works	Frontal	3
speed management	Presence of features to reduce operating speed	Frontal	3
bicycle facility	Presence of facilities for bicyclists	Frontal	2
quality of curve	Influence surroundings on cost of major works	Frontal	2
vehicle parking	Influence surroundings on cost of major works	Frontal	2
property access points	Influence surroundings on cost of major works	Frontal	2
area_type	Influence surroundings on cost of major works	Lateral	2
land use	Influence surroundings on cost of major works	Lateral	4
number of lanes	Influence surroundings on cost of major works	Frontal	5

Some of the models can identify all the classes or categories, others can help you sort through the available options.

Main Features

Some of the features now available are as follows:

• Scoring using the models already developed
• Grouping by groups of 5 images from an image list
• Download models directly into the root of the package

Instalation

To install you can use the following commands

pip install viasegura

Then to download the models use the following commands

from viasegura import download_models

download_models(aws_access_key = <aws_access_key>, aws_secret_key = <aws_secret_key> )

To obtain the corresponding credentials for downloading the models, please contact the Inter-American Development Bank.

You can also clone the repository but remember that the package is configured to download the models and place them in the root of the environment. You can change the locations manually as follows

from viasegura import download_models

download_models(aws_access_key = <aws_access_key>, aws_secret_key = <aws_secret_key>, system_path = <new_working_path>)

Remember to put that path every time you instantiate a model so that you can find the artifacts you need to run them.
