The directions of activities to be undertaken are:– Activities to reduce the risk of accidents, in particular caused by collisions with trees.– Activities to improve pedestrian safety and speed reduction.– Standards for the location of public transportation bus stops.– Elimination of dangerous places.– Ensuring internal current and reliable information about the state of road safety.– Information on the status of road safety for external customers.– Improvement of the procedures related to traffic management.– Modern and safe solutions—standard and unconventional.
Urban transportation planning
Published in Dinesh Mohan, Geetam Tiwari, Sustainable Approaches to Urban Transport, 2019
Several Indian cities have constructed or made plans for new flyovers. The justification for flyover construction is to reduce long delays at intersections and provide uninterrupted movement for long-distance traffic. However, flyover construction cannot provide long-term solutions because it improves journey times for only a small section of the road for cars that form only 20–25 per cent of the total commuter trips in a city like Delhi. In other cities, car trips are less than 20 per cent. It does not have any benefits for bus commuters because bus stop locations are shifted away from the intersection, increasing the walking distance for changing buses which go in different directions. With an increase in the speed of road vehicles, bus commuters as well as other pedestrians find it difficult to cross the road. Thus, flyovers result in short-term benefits for car users at the cost of increasing traffic hazards and inconveniencing other road users. They also encourage people to use cars and two-wheelers and to move away from public transport, walking and bicycling. This results in more vehicles, congestion and pollution on the roads. A careful look at the road widening and junction improvement schemes shows that widening has been done by reducing the space for pedestrians. Not a single city in India has implemented facilities for bicycles, public transport buses or IPT vehicles like three-wheelers and rickshaws. Junction improvement schemes have included creating free left-turns, shifting bus stops away from the junction and creating grade-separated junctions. In other words, investment in road infrastructure improvement has meant facilities for vehicles that carry a much smaller share of total trips compared to the trips by pedestrians and non-motorised vehicles.
A multi-stage stochastic optimization approach to the stop-skipping and bus lane reservation schemes

With the help of innovative the Advanced Driver Assistance System (ADAS) (including road perception, vehicle-vehicle, and vehicle-infrastructure communications and cooresponding technologies) and the driver-assistance system, the lane reservation strategy is developed to set temporarily dedicated lane for special transportation tasks, e.g. truck freight (Fang et al. 2011; Fang et al. 2013) and hazardous materials shipment (Zhou et al. 2012). Based on this concept, this paper proposes a hybrid bus operating strategy which combines the stop-skipping and lane reservation. In the general stop-skipping scheme, a bus is allowed to skip one or more stops to reduce its travel time if it is late and behind the schedule (Liu et al. 2013). In the proposed operating strategy, bus lane is reserved based on the bus stop-skipping plan: once a bus stop is skipped, a dedicated bus lane is reserved on its incoming or outgoing link (see Figure 1(a)), and it returns to normal lane till the bus arrives at the next stop (see Figure 1(b)). Private vehicles would be notified with the information of temporary bus lane before riding into it. As aforementioned, the proposed hybrid strategy is a combined optimization problem where the decision of the reserved bus lane is correlated with the stop-skipping scheme.
Quality of public transport service: an integrative review and research agenda
Published in Transportation Letters, 2019
There are several heated debates about how to conceptualize and measure service quality (Brady et al. 2002). This arises from a lack of clear and measurable parameters for determining service quality (Grzinic 2007). Bhat and Guo (2005) said the ability to improve public transport performance is closely tied to measuring it as a subject of the greatest interest to both planners and transport operators (Eboli and Mazzulla 2008). Three parts of public transport are measurable: ticketing, on board services and platform/bus stop or terminal facilities (Geetika 2010). For a transit trip, attributes of service are walking into the station or bus stop, waiting time for bus services, traveling time in the transit vehicle and walking time to the destination (Rabi and McCord 2006).
Built-environment risk assessment for pedestrians near bus-stops: a case study in Delhi
Published in International Journal of Injury Control and Safety Promotion, 2023

The model estimations indicate that height of sidewalk, way of crossing, bus stop shelter quality and lighting condition around the shelter as significant factors causing chances of pedestrian fatalities near bus stops. ANOVA test results, presented in Table 8, shows way of crossing bus stop lighting to be significant as well.
