This paper studies the effectiveness of the bus priority lane (BPL) for public transport buses in the city of Bengaluru in India. We use the travel times on the BPL corridor as a measure of the effectiveness of the BPL. We find that there is a significant improvement in the travel times after the introduction of the BPL; for the worst 10% of the travel times, we find an improvement between 4% and 28%. Our methodology involves extracting trips on the BPL and computing the travel times for these trips from a time series of GPS information. Our methodology is scalable and can be used to compute the travel times between any two given points in other similar studies. We supplement our results with a novel test (called the D-test) for comparing the levels of stressful driving in the following scenarios: (a) morning peak hours (IST 07:00 h to 11:00 h) versus evening peak hours (IST 17:00 h to 21:00 h), and (b) northward trips versus southward trips on the BPL. We are able to infer that the drivers are generally more stressed during the morning peak hours and during the southward trips on the BPL. Partitioning the BPL into segments, we show that a majority of the segments exhibit similar effectiveness and driver stress trends as the full BPL stretch. We anticipate that corrective measures for the betterment of travel times and driver stress levels (e.g., introducing additional buses subject to vehicle re-balancing constraints, carefully planning the bus schedules to regulate bus traffic throughout the day, etc.) in some segments can lead to further improvements in travel times and reduction in driver stress levels. • Implementation of the Bus Priority Lane can reduce travel times. • Segmented analysis helps identify traffic bottlenecks for targeted intervention. • Driver-stress hot-spots can be identified for targeted intervention. • A novel statistical test compares driving stress levels across a pair of routes.

Abstract: Rapid growth of the Information Technology (IT) sector in Bangalore, India, has transformed the city’s urban-industrial landscape since the liberalization of India''s economy in 1991. The city''s IT sector is closely integrated with a global system of production and caters largely to a global clientele. Apart from the impact of these developments on urban form, there are indications that they are causing uneven growth patterns and socio-economic polarization, which has resulted in different travel patterns in the work force. This paper compares the commuting patterns of employees in two types of firms, an IT multinational corporation and a traditional public-sector-unit (PSU), using data from a survey. Regression models show that there is a significant increase in travel cost as income rises for a sample of employees of the IT sector, even though travel distance is not influenced by income. The reverse holds true for a sample of employees of the PSU—rising income significantly increases distance though income does not affect travel cost. Behavioral choice models also show that with increasing income IT employees are more likely to choose two-wheelers and cars for commuting while PSU employees are more likely to choose public buses or walk to work. The paper suggests that Bangalore''s services-oriented IT economy is magnifying differences in work commuting patterns relative to those in the traditional manufacturing economy. The IT economy is also transforming travel behavior in terms of work travel mode choices among socio-economic groups. [Copyright &y& Elsevier]
