Advances in data and technology have created new opportunities to work on the evaluation of large infrastructure investments. The ieConnect for Impact program is generating a significant body of evidence through the development of data systems and experimental and quasi-experimental evaluations that can transform the way we think of mobility as an economic force and at a scale that will substantially improve the evidence-base for policy making. The ieConnect for Impact program is a collaboration between DIME and the World Bank Transport Global Practice.
Program Snapshot
- 37 impact evaluations (IEs) across 23 countries
- Focusing on urban mobility, transport corridors, road safety, and rural roads sectors
- Thematic emphasis on gender, female economic empowerment, fragile situations, environment, and climate
Leveraging Innovative Data
Transport IEs are typically on a larger scale, have more intensive data requirements, and present unique methodological challenges compared with IEs in other sectors. The ieConnect program has prioritized the development and expansion of data systems using new technologies to harvest large amounts of data at higher frequency or with greater geographic coverage and spatial resolution than traditional survey methods allow. This includes geospatial, crowdsourced, or sensor data, coupled with new and existing datasets. The data systems being developed allow research teams to mitigate methodological challenges—such as the fact that selection of project sites is not random and is often integral to project design—using rigorous IE methods. This, in turn, can build local capacity and strengthen government agencies’ basis for evidence-based decision making for transport investments in the long-term.
From the ieConnect program we will learn about how to improve the availability and quality of data that can be used for measuring the impact of transport projects, and generate evidence that can be used to improve decision making for transport investments in the long-term.
This program has been funded with UK aid from the UK government.
| Example Virtual Knowledge Sharing during COVID-19 | Presentation | |

On March 31, 2020, ieConnect presented on New Applications of Big Data for an Evidence-Based Analysis of Development Corridors in the virtual Transport Springboard Series organized by the Transport Global Practice. ieConnect has prioritized the development and expansion of large-scale data sets to support the projects Monitoring and Evaluation (M&E) framework and examine the impact of corridor investments on trade-related outcomes, local economic development, land use, and access to essential services in less developed and remote regions. The presentation reviewed sources for geospatial, crowdsourced, or sensor data and showcased how ieConnect has used them to complement existing survey or administrative data and to strengthen the measurement of project indicators. The presentation also showcased preliminary results and research designs, as well as data and tools generated and used in ongoing impact evaluations looking at the impact of transport corridors. In particular, the session focused on cases (Tunisia, Iraq, Pakistan, Ethiopia, Malawi, Guinea-Bissau and Southern Africa), where wider economic benefits of transport corridors are investigated through innovative data and models. |
Example Projects

The Rwanda Rural Feeder Roads IE analyses the impact of the large rural road upgrading program on markets and households, and its research questions are:
The data system developed on the rural roads IE has also been adopted by the government. It will be used to additionally measure the impacts on corridor projects, thus forming the basis for monitoring and evaluation for the entire transport sector. |
Smart and Safe Nairobi Transport (smarTTrans) Impact Evaluation | Presentation |
|
|
The smarTTrans project is developing a detailed real-time geo-referenced crash map of Nairobi. In the first stage the team is generating high-frequency data on crashes and crash density around urban hotspots and using a real-time verification process to record characteristics related to the crash. Once this process has been successfully tested for Nairobi, the code will be open and available so that this type of data collection can be expanded to other countries. The second stage will use the information on the characteristics of the different crash sites to conduct a series of experiments testing different types of interventions. A better understanding of which road safety interventions are most effective can be used to mitigate the health impacts of increasing motorization in Nairobi. |
Rio de Janeiro Gender Segregated Public Transport Impact Evaluation | Presentation |
|
|
Sexual harassment on a woman’s commute is pervasive and widens the gender wage gap. To capture the economic costs of this violence, we randomized the price of a women-reserved “safe space'” in Rio de Janeiro, Brazil. We recruited 363 women riders to crowdsource information on their behavior and experience across 22,000 rides. Women riding in the public space experience harassment once a week. A fifth of riders are willing to forgo the equivalent of a 20% fare subsidy to ride in the "safe space". Randomly assigning riders to the “safe space" reduces the incidence of physical harassment by 50%, implying a cost of avoiding physical harassment of $1.45 per incident. While the reserved space is safer in relative terms, Implicit Association Tests reveal that commuters associate women riding in the public space with more openness to sexual advances. The welfare implications of creating women-reserved spaces are ambiguous. |
Example Workshop
 |
From December 3–6, 2019 the DIME team and the Transport Global Practice (GP) held the fourth impact evaluation workshop of ieConnect in Marrakech, Morocco. The workshop brought together 69 participants from 28 organizations. The participants included project team leaders from the GP, government officials from 8 different countries, academics, and IE specialists from institutions such as the Inter-American Development Bank. The workshop consisted of training sessions on IE measurements, targeted project group work “clinics”, and panel discussions. Each project was assigned a research team to develop the IE designs. This process served to enhance the capacity of the GP staff and client counterparts to design rigorous IEs and of clients to generate data on the impact of transport interventions. The teams incorporated road safety, green transport, climate and gender considerations in the designs, which are key priorities for the GP. This workshop serves as an example of how ieConnect is influencing transport projects during design or implementation. |
