Purpose — This study assesses the effectiveness of initiatives by expatriate employees of the American Telephone and Telegraph Company (AT&T, popularly referred to as the ‘Bell System’11The use of the term ‘Bell System’ as a synonym for AT&T reflected the firm's initial dependency on the exploitation of the telephone patents of Alexander Graham Bell. The Bell System consisted of AT&T, a holding company, and its affiliates including The Bell Telephone Laboratories (research), Western Electric (manufacturing) and 13 regional telephone operating subsidiaries.) in the revival of the Japan's telecommunications system and allied industries after World War II.

Methodology — Our primary methodology involves historical analysis of archival resources for AT&T and the Civil Communications Section (CCS) of the Supreme Command Allied Powers (SCAP), the American occupation government agency responsible for advising Japanese government and industry during the period 1945–1950.

Findings — Before the war, the Bell System maintained strong direct connections in Japan. AT&T's influence during the occupation, however, was indirect: knowledge dissemination through the activities of the CCS, which had several employees on loan from the Bell System.

Research limitations/implications — While our sample of organisations seems narrow and the duration of time relatively brief, the Bell System's people made a tremendous impact: transforming the Japanese telecommunications system. This suggests that guidance and tutelage by expatriate experts may enable host countries to master best practices rapidly without incurring high costs of evolutionary development.

Social implications — Local social mores and differences in workforce educational attainment may temporarily impede the acceptance of new foreign approaches to management and administration.

Value of the chapter — This chapter demonstrates how firm-specific and proprietary knowledge built up over decades at one firm could, through the agency of expatriates, revolutionise in just a few years the basic approaches followed in another country's telecommunications industry.

This research paper aims to investigate the effects of gradual deployment of market penetration rates (MPR) of connected vehicles (MPR of CVs) on delay time and fuel consumption.

A real-world origin-destination demand matrix survey was conducted in Boston, MA to identify the number of peak hour passing vehicles in the case study.

The results showed that as the number of CVs (MPR) in the network increases, the total delay time decreases by an average of 14% and the fuel consumption decreases by an average of 56%, respectively, from scenarios 3 to 15 compared to scenario 2.

The first limitation of this study was considering a small network. The considered network shows a small part of the case study.

This study can be a milestone for future research regarding gradual deployment of CVs’ effects on transport networks. Efficient policy(s) may define based on the results of this network for Brockton transport network.

This study aims to make full use of the advantages of connected and autonomous vehicles (CAVs) and dedicated CAV lanes to ensure all CAVs can pass intersections without stopping.

The authors developed a signal coordination model for arteries with dedicated CAV lanes by using mixed integer linear programming. CAV non-stop constraints are proposed to adapt to the characteristics of CAVs. As it is a continuous problem, various situations that CAVs arrive at intersections are analyzed. The rules are discovered to simplify the problem by discretization method.

A case study is conducted via SUMO traffic simulation program. The results show that the efficiency of CAVs can be improved significantly both in high-volume scenario and medium-volume scenario with the plan optimized by the model proposed in this paper. At the same time, the progression efficiency of regular vehicles is not affected significantly. It is indicated that full-scale benefits of dedicated CAV lanes can only be achieved with signal coordination plans considering CAV characteristics.

To the best of the authors’ knowledge, this is the first research that develops a signal coordination model for arteries with dedicated CAV lanes.
