TRAVEL MODE CHOICE INTENTION IN REDUCING TRAFFIC CONGESTION IN KAJANG, SELANGOR

The intentions behind a person’s choice of transportation mode is vital information to have in strategic planning for a sustainable transportation system, and is very useful in predicting the behaviours of people. This paper was conducted to identify people's preferences of public transport. Using the Theory of Planned Behaviour (TPB) as the psychological determinant, three main indicators, attitude, subjective norm and perceived behavioural control (PBC), were explored to identify the mode choice of public transportation among the residents of Kajang. The data was obtained through questionnaires by employing a multistage sampling technique, where 348 respondents were approached. Partial Least Square (PLS) analysis showed that attitude was the dominant indicator among residents of Kajang for modes of public transport. This paper will contribute to the advancement of knowledge in the theory of mobility and travel behaviour, as well as act as baseline data for predicting people’s travel behaviour in future mode shift strategies dealing with everyday issues of traffic, such as congestion.

Rebuilding Sustainable Commuting in Christchurch? A mixed-methods study of the effects of workplace relocation on transport choice and emissions

<p>Tackling the challenge of climate change will require rapid emissions reductions across all sectors, including transport. This study adds to the literature by investigating factors that may encourage sustainable transport choices at a time of change and therefore reduce emissions. A mix of quantitative and qualitative methods was used to explore the impact of a relocation of employees from several dispersed work locations back to one office building in the central business district on transport choices and carbon emissions in Christchurch, New Zealand. This case study found that such a recentralisation of employment can result in employees making more sustainable transport choices and can contribute to decreases in transport emissions from commuting, even in a highly car-dependent city. The relocation led to a 12 percent rise in the proportion of employees commuting actively or by public transport and resulted in a significant drop in commuting emissions (16 percent). The primary contributing factor was the change in location of the office itself, reducing the average commuting distance and increasing accessibility to public transport and active travel. A further contributing factor was the perceived reduction in parking availability at the new location. Further results support the existing literature on barriers to sustainable transport, identifying any factor that impacts on the feasibility of the journey by alternative modes, such as commute time or safety, as a significant barrier to uptake. Overall findings suggest that relocating offices provides a good opportunity to encourage employees to consider changing to a more sustainable commute mode, and that significant numbers may make such a shift if commute time or distance are reduced. Realising substantial mode shift however will depend on cities providing feasible and efficient sustainable alternatives to driving a car to work.</p>

A data-driven analysis of the potential of public transport for German commuters using accessibility indicators

Background A significant mode shift will be required in order to meet the ambitious greenhouse gas emissions reduction targets in Germany and elsewhere. Such a mode shift can only be achieved by a combination of drastic push and pull measures. Getting commuters to switch modes might be particularly difficult and have a negative impact on their access to employment and welfare. Methodology We investigate the potential for a mode shift from car to public transport for German commuters using a data-driven approach based mainly on open data sources that avoids complex transport model runs. Different datasets on the home and workplace location of all employees in Germany are consolidated to create an origin-destination commuter matrix at traffic analysis zone level. The commuter matrix is merged with travel time data for car and public transport to calculate a spatially disaggregated and mode-specific measure of accessibility. The comparison of accessibility by car and public transport is used to derive the potential for a mode shift and identify potential challenges and barriers. Results Public transport accessibility to workplaces is poorer across the country compared to access by car. On average, public transport travel times are almost three times higher than the corresponding car travel times. The differences in accessibility are largely independent of the region type. Results are validated by an independent dataset from a household travel survey. Based on these results, the potential for a mode shift appears to be very low.

Case Article—Coastal Shipping for Automobile Distribution

With growing concerns related to the environment, sustainable transportation has gained importance. For geographies with an ample coastline, coastal shipping offers a sustainable transportation option to move massive freight quantities. This paper presents a case that allows students to appreciate the role of coastal shipping in multimodal logistics planning. Furthermore, it gives students an opportunity to mathematically model transportation planning at a strategic and tactical level for automotive distribution. The students learn how to assess the financial viability of a mode shift from roadways to coastal shipping. The instructors can use this case for theoretical discussion on multimodal logistics and the application of mixed-integer linear programming (MILP) and heuristics as solution methods. Furthermore, the case presents an opportunity to demonstrate the improvement in solution quality with an MILP solver compared with heuristics.

0.75 Gbit/s high-speed classical key distribution with mode-shift keying chaos synchronization of Fabry–Perot lasers

High-speed physical key distribution is diligently pursued for secure communication. In this paper, we propose and experimentally demonstrate a scheme of high-speed key distribution using mode-shift keying chaos synchronization between two multi-longitudinal-mode Fabry–Perot lasers commonly driven by a super-luminescent diode. Legitimate users dynamically select one of the longitudinal modes according to private control codes to achieve mode-shift keying chaos synchronization. The two remote chaotic light waveforms are quantized to generate two raw random bit streams, and then those bits corresponding to chaos synchronization are sifted as shared keys by comparing the control codes. In this method, the transition time, i.e., the chaos synchronization recovery time is determined by the rising time of the control codes rather than the laser transition response time, so the key distribution rate is improved greatly. Our experiment achieved a 0.75-Gbit/s key distribution rate with a bit error rate of 3.8 × 10−3 over 160-km fiber transmission with dispersion compensation. The entropy rate of the laser chaos is evaluated as 16 Gbit/s, which determines the ultimate final key rate together with the key generation ratio. It is therefore believed that the method pays a way for Gbit/s physical key distribution.

Steps to Supplement Park-and-Ride Public Transit Access with Ride-and-Ride Shuttles

Public transit ridership in California declined in the five years before the pandemic of 2020–21 and dropped significantly further after the pandemic began. A sharp downward step in the level of transit boarding occurred after February 2020, and continues to the date of this report as a result of the public-health guidance on social distancing, expanded work-at-home, and a travel mode shift from public transit to private cars. A critical issue has come to the foreground of public transportation policy, namely, how to increase the quality and geographic reach of transit service to better serve the essential trips of mobility disadvantaged citizens who do not have access to private vehicle travel. The research focus of this report is an examination of the circumstances where fixed route bus route service could cost-effectively be replaced by on-demand microtransit, with equivalent overall zone-level efficiency and a higher quality of complete trip service. Research methods were reviews of documented agency experience, execution of simple simulations, and sketch-level analysis of 2019 performance reported in the National Transit Database. Available evidence is encouraging and suggestive, but not conclusive. The research found that substitutions of flexible microtransit for fixed route buses are already being piloted across the U.S., with promising performance results. The findings imply that action steps could be taken in California to expand and refine an emphasis on general purpose microtransit in corridors and zones with a relatively high fraction of potential travelers who are mobility disadvantaged, and where traditional bus routes are capturing fewer than 15 boardings per vehicle hour. To be sufficiently productive as fixed route replacements, microtransit service technologies in the same or larger zones need to be capable of achieving vehicle boardings of five per hour, a challenge worth addressing with technology applications. Delivery of microtransit service can be undertaken through contracts with a growing set of private sector firms, which are developing processes to merge general purpose customers with those now assigned to ADA-required paratransit and Medi-Cal-supported non-emergency medical transport.

The Evaluation of Mode Shift Preference within Bus Rapid Transit-oriented Development Context

Bus rapid transit (BRT) has been acknowledged as a mode of transit that is appropriate to be constructed in conjunction with transit-oriented development (TOD). In order to evaluate the occurrence of a TOD with BRT systems as its component, evaluating the passengers’ mode shift triggered by the provision of the BRT systems is one approach that can be taken. Within the mentioned type of TOD, the built environment should support, or even more trigger, the passengers’ mode shift into taking the BRT systems. This article evaluates the mode shift preference of Transjakarta BRT passengers. This article also evaluates the heterogeneity of mode shift preference among various groups of Transjakarta passengers. This article qualitatively describes the mode shift preference, while the data was collected, processed, and presented in quantitative manners. Information regarding the mode shift preference is collected through an indirect interview. The statistics of the mode shift preference is processed using simple statistical analysis and Bartlett’s test for variance heterogeneity. It is found that the role of the built environment in supporting Transjakarta passengers’ mode shift into taking Transjakarta is relatively low. It is also found that the variance of the mode shift preference is homogeneous across various groups of Transjakarta passengers. This article concludes that the envisioned bus rapid transit-oriented development (BRTOD) hasn't been fully occurring in areas around Transjakarta corridors.
