Article
Literature has suggested that angle/rear-end collisions would arise from the reality that motorists and motorcyclists tended to accelerate aggressively in response to the remaining seconds of green signal countdown device (GSCD). One safety concern, while GSCD has gradually been removed for safety in Taiwan, is pedestrian green signal countdown dev...
Article
To combat gas emissions produced by idling motorcycles at red lights, Taiwan government passed an “idle-stop (IS)” bill that requires manufacturers from year 2015 to equip 10% of newly-manufactured motorcycles with a microchip enabling the idling engines to be automatically off. Along with the safety concerns over the new but controversial technolo...
Article
In order to reduce CO2 emissions from motorised transport, the Taiwanese government implemented an idling policy for vehicles in 2012. This paper applies a contingent valuation framework based on stated preference questions to calculate a reasonable fine for idling vehicles based on drivers’ preferences in Taiwan. Drivers were surveyed at urban roa...
Article
Literature has suggested that bicyclists' red-light violations (RLVs) tend not to cause accidents although RLV is a frequent and typical bicyclist's behaviour. High association between bicyclist RLVs and accidents were, however, revealed in Taiwan. The current research explores bicyclists' RLVs by classifying crossing behaviours into three distinct...
Article
A triple-bounded dichotomous choice (TBDC) structure and Spike models are applied to investigate the amount of money Taiwan automobile drivers are willing to pay for five types of moving violations, including local street speeding, expressway and freeway speeding, red light running, right turn on red, and drink-driving. Face-to-face survey was cond...
Article
Research has suggested that the most typical and catastrophic automobile-motorcycle crash takes place when an automobile manoeuvres into the path of an oncoming motorcycle at intersection, which involves a motorist infringing upon the motorcycle's right of way (ROW). In Taiwan, motorcycles, on the other hand, are the one that has been observed to v...

Recent emphasis on bicycling as an alternative to automobile transportation has underscored the need for research efforts directed at bicycle safety when sharing roadways with motorised vehicles. Much of the research attention is focused on junction accidents where motorists tend to infringe upon bicycles' right of way. Non-junction accidents where...
Article
Evidence in literature suggested that motorists’ failure to give way to motorcycles at junctions is the main contributory factor to motorcycle–car accidents that involve gap acceptance (i.e., approach-turn and angle crashes). This paper attempts to examine how motorist’s failure to give way affects motorcyclist injury severity in angle crashes at T...
Article
Research suggested that motorists' right-of-way (ROW) violation in automobile-motorcycle gap-acceptance accidents at priority (i.e., stop-/yield-controlled) T-intersections has been a safety concern to motorcyclists. This study examines the characteristics of automobile-motorcycle gap-acceptance accidents that occurred at such locations. British St...
Article
Motorcyclists tend to be more vulnerable to injuries than those using other motorised vehicles and this may act synergistically with the complexity of conflicting movements between vehicles and motorcycles to increase injury severity in a junction-type accident. A junction-type crash can be more severe to motorcyclists than a non-junction case due...
Article
Research has suggested that motorcyclists involved in approach-turn crashes were much more injurious than any other crash-type. This paper investigates the determinants of motorcyclist injury severity resulting from such crash types that occurred at T-junctions, with emphasis on the effects of driver's failure to give way and various junction contr...
Article
Sideswipe collisions between motorcycles and other motorised vehicles are one of the frequently occurring types of crashes at junctions in the United Kingdom and such collisions can be injurious to motorcyclists due to their vulnerability to injuries in nature. Research focusing on vehicle–bicycle sideswipe crashes has suggested that vehicles shunt...
Article
The effects various junction control measures have on accident frequencies among vehicles have been investigated by previous studies through the use of statistical modelling techniques but such effects on motorcyclist injury severity, given that a junction-type accident has occurred, have received little attention in literature. This paper attempts...
