HSL combined all web services under one roof – CGI involved in renewing the user interface

HSL has implemented an extensive reform of its online services, including the incorporation of the popular Reittiopas journey planner in The project was carried out in a multi-vendor environment, with CGI Finland responsible for the renewal of the Reittiopas user interface.

In the spring of 2020, Helsinki Region Transport (HSL) launched a major online service reform with the goal of improving the usability of the new website. The aim was also to ensure that all the necessary information related to public transport could be found on the website faster. For this reason, the previously separate Reittiopas service was combined under the same roof with other HSL online services.

“We’ve made the look and feel of our website and the journey planner even clearer. Special attention has also been paid to accessibility. The starting point for the reform was the needs and wishes of our customers,” says Milla Laita, product owner of Digitransit at HSL.

In the multi-vendor environment, HSL’s long-term partner CGI was also responsible for the technical implementation.

“CGI has been involved in the development of the HSL Reittiopas since 2001. This has provided us with a solid understanding of the industry and customer needs. We have strong expertise in geographic information and public transport information systems,” says Elina Ruokari, Customer Relationship Manager at CGI.

Smooth cooperation across boundaries

The new user interface was built in a multi-vendor environment, where different aspects of the project, such as coding and visual design, were the responsibility of different parties.

“One success factor in the project was seamless collaboration across organisational boundaries. Since most of the results needed to be sharable from the start, particular attention has been paid to quality. In this project, all parties have certainly been motivated by the relevance of the work: the results affect the mobility of more than a million people,” says Vesa Meskanen, Systems Specialist at CGI.

The user interface renewal was implemented based on the DevOps model using agile development methods and the JavaScript React platform. The solutions will be implemented for HSL as docker micro services in the Microsoft Azure cloud.

“The Reittiopas journey planner is a popular service, which promotes the transition to lower-carbon modes of transport and provides significant time savings for end users looking for information,” explains Milla Laita from HSL.

The HSL journey planner is based on the open source Digitransit service platform, which is partially developed and maintained by CGI. The Digitransit service platform has been built with funding from the twenty owner municipalities of HSL, Traficom and the TVV ticket and payment systems for the routing of public transport in Finnish urban areas.

The HSL Reittiopas service is the most popular online transport service Finland. HSL and CGI have been developing public transport services together for 30 years.
