choose which elements of the network (i.e., vehicles, bus stops,
etc.) she wants to improve and with which optimization criteria.
Information regarding the public urban transportation network of
the city under investigation Information regarding the travelers
demand, i.e. which are the most frequent trips Information
regarding the features of the trips composing the travel demand.
Analyzes the performances of the urban public transport network and
suggests which are the best transportation infrastructure
investments to improve the travelling experience of people with
disabilities System to measure the quality of a public
transportation network for people with disabilities, and recommend
improvements 3. IBM Research - Ireland 2012 IBM Corporation London
case study: the problem The London Journey Planner
(http://journeyplanner.tfl.gov.uk) suggests the above path from
Victoria and Albert Museum to Tate Modern Gallery on the 09 Aug
2012 at 11:35: note how the shortest path that uses all vehicles
accessible by people with reduced mobility is 2 times longer and
requires more interchanges. (a) With the reduced mobility
constraint (b) Without any reduced mobility constraint 4. IBM
Research - Ireland 2012 IBM Corporation How accessible is the
public transportation system of London for people with
disabilities? Using the Origins-Destinations obtained from Oyster
Card data to simulate travel demand, we evaluated the routes
provided by a journey planner if we require trips to be
wheelchair-accessible, and compare them with the shortest routes.
Findings: 1.50% of the trips are at least 50% longer if we require
the trip to be wheelchair- accessible; 2.Wheelchair-accessible
routes require travelers to exchange among more modes (on average
1.11 times more) 5. IBM Research - Ireland 2012 IBM Corporation

provide the highest positive impact for the mobility of people with
