ADD2249 TravelTime platform API - renewal

Type of decision: 
Assistant Director's decision
Code: 
ADD2249
Date signed: 
19 July 2018
Decision by: 
Jeremy Skinner, Interim Assistant Director, City Intelligence Unit

Executive summary

The GLA produces a number of interactive web maps for use by the public and professionals. The ability to show travel times from a chosen location and to filter search results by travel time and mode adds value to high profile maps including the London Schools Atlas.
The TravelTime platform from iGeolise is based on a regularly updated database of timetables including national rail services, as well as TfL run services. As well as public transport, it provides estimates of walking, cycling and driving times.

The licence will allow the GLA to access the TravelTime platform via its API, sending a series of queries and receiving answers in return.

Decision

That the Assistant Director of Intelligence Unit approves expenditure of £24,000 for 24 months access to the Travel Time API 1st April 2017 – 31st March 2019

Part 1: Non-confidential facts and advice

Introduction and background

The GLA produces a number of interactive web maps for use by the public and professionals. The ability to show travel times from a chosen location and to filter search results by travel time and mode adds value to high profile maps including the London Schools Atlas and Workspaces map.

The 2050 Infrastructure Mapping Application contains information about over 12,000 development projects across London and over the next 20 years. At present, users can filter the projects by area (such as Ward, or Opportunity Area). However, the next stage of development requires the ability to show the benefits of new infrastructure and model the impacts of construction. Both of these are best understood by time contours as well as distance contours.

The TravelTime platform from iGeolise is based on a regularly updated database of timetables including national rail services, as well as TfL run services. As well as public transport, it provides estimates of walking, cycling and driving times. The API has been in use by the GLA since 2014 covered by DAR ‘Travel Time Search API’ (4/11/2014) and ADD 2005.

There are three particular requirements for the solution:

a) the ability to generate a ‘travel catchment’ or contours based on a chosen location, travel mode and maximum time
b) work via an API behind the scenes, meaning that users don’t have to navigate away from the GLA map to visit another page (or that large numbers of options have to be predefined and stored)
c) charging plan that allows for a large number of different queries to be submitted and contours to be created (this is needed to support public facing GLA web maps where a user could click anywhere in London to generate a catchment)

Three competitive quotations were sought by the GLA in preparation for this ADD. TfL provide journey planning APIs (as do several other organisations). However these are on a point to point basis giving you a suggested route, rather than automatically generating travel time areas. Other services were able to offer contours for some travel modes, but not all four required. Finally another service didn’t access the full range of timetables for different public transport modes. The outcome of quotation process was that iGeolise provided the closest product to the requirements.

Objectives and expected outcomes

The licence will allow the GLA to access the TravelTime platform via its API, sending a series of queries and receiving answers in return.

The API will be accessed initially by the following GLA maps:

- Schools Atlas
- Cultural Infrastructure map
- 2050 Infrastructure Mapping Application

Equality comments

The GLA has considered the potential impacts on those with protected characteristics, as identified by the Public Sector Equality Duty (PSED), that might arise from this proposal. There are no particular impacts arising. The GLA seeks to maintain high-levels of accessibility to its web information, including maps, and this will be kept under review to ensure compliance with best practice standards.

Other considerations

a) key risks and issues

Possible risk – Non delivery
Mitigation – Delivery is via web-based key, available immediately

Possible risk – transport data is out of date
Mitigation – data is updated weekly

Possible risk – Not compatible with GLA systems
Mitigation – Uses well established web standards and is already in use on GLA web applications

b) links to Mayoral strategies and priorities

Schools Atlas - The Atlas is part of the Mayor's programme of initiatives aimed at driving up standards in education and ensuring there are enough places for all children in the city.

2050 Infrastructure Map – Ensuring that there is sufficient infrastructure to support London’s projected population growth.

Financial comments

The estimated cost of up to £24,000 will be funded from the 2018-19 Ordnance Survey budget within the Intelligence Unit.
